Rotational, Translational, Oscillatory (Vibratory) and Deformation

The last one is not traditionally thought of but while a spring moves on a linear path it is caused by deformation of the metal. Your teacher is probalby looking for the first three. In Kinematics only the first three are considered the science of Dynamics is devoted to the fourth.

Rotational = planets orbits
Translational = projectile path or linear
Oscillatory (Vibratory) = periodic like a pendilum, vibrations as in the vibrations of a string or the oscillating movement of a photon which moves in a linear fashion while vibrating (that sets the frequency)
Deformation = motion inside of an object like tension, buckling, twisting, compression, or expansion.

According to Wikipedia: http://en.wikipedia.org/wiki/Kinematics
“Kinematics (Greek κινειν,kinein, to move) is a branch of mechanics which describes the motion of objects without the consideration of the masses or forces that bring about the motion. In contrast, dynamics is concerned with the forces and interactions that produce or affect the motion.
Kinematics studies how the position of an object changes with time. Position is measured with respect to a set of coordinates. Velocity is the rate of change of position. Acceleration is the rate of change of velocity. Velocity and Acceleration are the two principal quantities which describe how position changes.”

Types of Motion: According to: http://carini.physics.indiana.edu/E105/types-of-motion.html

- Translation: Motion along a path
examples: Position, Velocity, Net force
- Rotational: Rigid of a body about an axis
- Rotational: Orientation of the axis, Angular position,
- Deformation: Bending, stretching, twisting,
examples: Internal elastic forces, springs, tension and compression

According to: http://hypertextbook.com/physics/mechanics/introduction/
"1. Translational motion results in a change of location. This category may seem ridiculous at first as motion implies a change in location, but an object can be moving and yet not go anywhere. I get up in the morning and go to work (an obvious change in location), but by evening I'm back at home (back in the very same bed where I started the day). Is this translational motion? Well, it depends. If the problem at hand is to determine how far I travel in a day, then there are two possible answers: either I've gone to work and back (thirteen miles each way for a total of 26 miles) or I've gone nowhere (thirteen miles each way for a total of zero miles). The first answer invokes translational motion while the second invokes oscillatory motion.

2. Oscillatory motion is repetitive and fluctuates between two locations. In the previous example of going from home to work to home to work I am moving, but in the end I haven't gone anywhere. This second type of motion is seen in pendulums (like those found in grandfather clocks), vibrating strings (a guitar string moves but goes nowhere), and drawers (open, close, open, close -- all that motion and nothing to show for it). Oscillatory motion is interesting in that it often takes a fixed amount of time for an oscillation to occur. This kind of motion is said to be periodic and the time for one complete oscillation (or one cycle) is called a period. Periodic motion is important in the study of sound, light, and other waves. Large chunks of physics are devoted to this kind repetitive motion. Doing the same thing over and over and going nowhere is pretty important; which brings us to our next type of motion.

3. Rotational motion occurs when an object spins. The earth is in a constant state of motion, but where does that motion take it? Every twenty-four hours it makes one complete rotation about its axis. (Actually, it's a bit less than that, but let's not get bogged down in details.) The sun does the same thing, but in about twenty-four days. So do all the planets, asteroids, and comets; each with its own period. (Note that rotational motion too is often periodic.) On a more mundane level, bocce balls, CDs, and wheels also rotate. That should be enough examples to keep us busy for awhile."

According to: http://www.mcasco.com/p1mot1d.html
"There are three types of motion that we will study in mechanics. These are TRANSLATION, ROTATION and VIBRATION. Translation is motion along some path from one place to another, like a car moving down a highway. Rotation is motion around some axis, like the Earth's daily motion. Vibration is a back and forth motion like the pendulum of a clock. For the purposes of this lesson we will not consider rotation, limiting ourselves to motion in a straight line. This simplification eliminates the need to use vectors to measure the quantities describing the motion. The straight-line motion is the reason we use 1 Dimension in the title of this lesson. Also by placing this restriction on the motion we will study, we only need to consider objects that are particles , meaning that their size does not enter into our consideration."

Simple Types:

Translation (Motion along a path)
Rotation
Deformation

Examples of complex motion broken down:
A thrown ball
typically the ball is moving through the air along some path, but at the same time it is rotating. We can describe its motion through the air by the position and velocity of the center of the ball, its rotation by the axis of rotation and the rotational rate of the ball. An important force in determining the path, gravity, does not change the rotational motion.
A diver or gymnast in the air with a straight body
As long as the athlete's body is held fairly straight, the situation is the same as for a thrown ball (we just need to follow the position of the athlete's center of mass and give the axis of rotation, orientation, and speed). In this situation, the laws of physics apply in exactly the same way for the gymnast as for the ball, both can be viewed as "projectiles" moving only under the influence of gravity and air resistance.
A diver or gymnast in the air that bends
Of course, the athlete's body may bend while in the air, which necessitates some new physics compared to the "projectile" model. Interestingly, the motion of the athlete's center of mass is not directly affected by bending in the air (the rotational motion is affected,however).
A swung golf club (or baseball bat or hockey stick)
Again, there is a translation (motion of the center of mass) and rotation at the same time. The only difference compared to a projectile is the force exerted by the hands at the handle. We can use this to our advantage: it would be difficult to measure the force of the hands on the club directly, but once we understand projectile motion the fact that the only other force acting on the club is the hands at the handle will enable us to deduce the strength and direction of that force from the motion of the club.
The golfer's forearm during a swing
Similar to the club, the golfer's forearm translates and rotates. additionally, there will be force exerted on the forearm at just two points: at the wrist from the hands and at the elbow from the upper arm.
Collisions
Not all motion in sports is smooth. Frequently there are very fast changes in one or more of the simple components of motion when two objects collide. For example, the translational (and rotational) motion of a ball changes very rapidly (in 1/2000 second) when struck by a golf club (the translational motion of the head of the golf club changes rapidly also). The gymast's translational and rotational motion changes abruptly in a brief time before the twisting forward vault (a collision between the gymnast's feet and the floor).
Although all these abrupt changes occur because of forces, torques, and elastic forces, they happen so fast that we cannot usually observe the motion well enough to follow the objects during the collision itself (standard video is 30 or 60 frames per second). Therefore we cannot learn about the forces directly by observing the moving objects. Later we will learn how to understand collisions and the forces that act during them. For now, it is important to identify when a collision occurs: in between collisions, forces change slowly enough that by measuring the motion of objects we can figure out the forces acting.

This is not the sort of question that has a definite answer, and answering it will not impart much real knowledge of physics. It suffers from what might be called classification ambiguity. A question of a similar sort is, what are all the types of trees? Evergreen and deciduous? Nut trees, fruit trees, berry trees, conifers, ...? Tropical and temperate? Terrestrial and aquatic? Blossoming and non-blossoming? Short, medium, tall? They can be divvied up in lots of different ways, and so can people, and so can rocks, and so can motion. And for any one of these things, the different ways of classifying it, overlap with each other. Motion can be: • rectilinear (constant speed in a straight line) or accelerated • uniform or nonuniform • linear, circular, or otherwise curved • relativistic or non-relativistic • periodic, secular, or irregular • In air or other fluid, it can be subsonic, transonic, or supersonic • orbital motion can be closed or open; it can also be circular, elliptical, parabolic, or hyperbolic There is no exhaustive list. I recommend narrowing your focus.

1. A pendulum exhibits Simple harmonic motion, or, motion that is constantly being accelerated towards a midpoint.

2. Other types of motion include Linear motion and Reciprocation. Examples of naturally occurring motion are Brownian Motion (the movement of particles), and the orbits of planets

I hope it helps!

The easiest way to learn golf like a pro is by following "The Simple Golf Swing" program. It's primarily a 31 page eBook that teaches golfers how to make solid contact with the ball, how to avoid hitting fat, how to avoid slicing, how get more power, accuracy, and consistency in your swing. Consistency being the number 1 golf skill.

You not only get the eBook though, you also receive a ton of extra material including video, lessons on putting, driving, chipping, sand play etc. Here is their official site: http://www.golfswingguru.net
