Is acceleration and motion the same thing?

Answer 1

No,

Acceleration is a measure of force which doesn't necessarily mean the object is in motion. for instance every object on the earth is accelerating towards the center of the earth at 9.8 m/s but the object while being accelerated is not necessarily moving, such a book just sitting on a desk it has acceleration but no movement.

Motion is a measure of displacment and it can be affected by acceleration as acceleration changes the rate of motion over time.

Answer 2

Acceleration is the rate of change of velocity with direction. While motion is change in position with time.

There might be situation, when there is motion but no acceleration e.g. object moving in straight line with constant velocity.

And whenever there is acceleration - there shall be a change in state of motion.

So, acceleration and motion are not same but may be dependent.
I hope that helps.

Answer 3

No. They aren't.
When a body is moving, if the magnitude and direction of its speed is the same ( in other words if the velocity is the same ), then the body is in motion, but has no acceleration.

When there is a rate of change of velocity of the body at any instant, the body has acceleration at that instant.

A body having acceleration at any instant may have zero or non-zero velocity ( motion ) at that instant meaning it may or may not have motion at that instant.

Answer 4

No, motion is pure movement not a specific type.

According to Wikipedia: http://en.wikipedia.org/wiki/Motion_%28physics%29
"In physics, motion means a continuous change in the position of a body relative to a reference point, as measured by a particular observer in a particular frame of reference."

Velocity is the speed that your are moving at and that can be motion.
Acceleration is the amount of speed increase that you are moving at and that too can be motion.

According to Wikipedia: http://en.wikipedia.org/wiki/Velocity
"In physics, velocity is defined as the rate of change of position. It is a vector physical quantity, both speed and direction are required to define it. In the SI (metric) system, it is measured in meters per second (m/s). The scalar absolute value (magnitude) of velocity is speed. For example, "5 metres per second" is a speed and not a vector, whereas "5 metres per second east" is a vector. The average velocity (v) of an object moving through a displacement (Δx) in a straight line during a time interval (Δt) is described by the formula:

v = Δx / Δt

Simply put, velocity is displacement per unit of time."

According to Wikipedia: http://en.wikipedia.org/wiki/Acceleration
"In physics, acceleration is defined as the rate of change of velocity, or, equivalently, as the second derivative of position. It is thus a vector quantity with dimension length/time². In SI units, acceleration is measured in metres/second² (m·s-²). The term "acceleration" generally refers to the change in instantaneous velocity."

Answer 5

Acceleration is the time rate of change of velocity with respect to magnitude or direction.

Motion is the action or process of moving or of changing place or position.

Recommend you use the web to look for definitions that are authoritative and written by lexicographers who presumably know what they are doing.

Answer 7

not the same, but correlated.
motion is the movement of a mass or body
acceleration is the rate of increase of movement of the mass or body.
