Which measurement is used for kinetic energy?

Question

Is it meters or centimeters?

Answer 1

Kinetic energy is measured in Joules (J)

1J = 1 kg(m^2/s^2)
1J = 1N*m

Both have meters, so you would want meters preferably.

MEASURING KINETIC ENERGY CONCEPTS: Kinetic energy, mass, velocity, friction BACKGROUND: The KE of a moving object can be measured by observing how far it can drag an object it collides with. A small mass object moving fast can have as much kinetic energy as a larger object moving slowly. EQUIPMENT NEEDED: Marbles or other small balls of various mass, ruler or other guide track, lined paper and tape, stopwatch ACTIVITIES: 1. Make a V-shaped catcher from cardboard, a 5x8 index card, etc. Tape the lined paper and the ruler down to a flat surface. Mark the starting point for the catcher, making sure it is exactly in line with the ball the marbles take. Flick the marble along the track and time how long it takes from when it leaves the track until it hits the catcher. Precise timing is tricky. It will take practice. The longer the distance from the ruler to the catcher the longer the time is and the easier to time accurately, but the more the marble will slow down due to friction. If no stopwatch is available, rough qualitative comparisons can still be made. Measure the distance from the end of the track to the catcher v=d/t. Note how far the catcher is dragged by the marble. Note the effect of varying speeds and masses. 2. Do the same experiment on a larger scale with larger balls rolled across the floor into a larger catcher made from a cardboard box. Try different designs for the catcher. Use baseballs, tennis balls, softballs etc. The balls can be rolled without a track to guide them is care is taken to hit the catcher in the center. Again note the effects of mass and velocity. CONNECTIONS: The faster a car is going, the longer the distance required to stop.

Answer 3

Joule is the measurement for kinetic engery.
Kinetic energy is a scalar quantity; it does not have a direction. Unlike velocity, acceleration, force, and momentum, the kinetic energy of an object is completely described by magnitude alone. Like work and potential energy, the standard metric units of measurement for kinetic energy is the Joule. As might be implied by the above equation, 1 Joule is equivalent to 1 kg*(m/s)^2.

Answer 4

Depends on your preference. The mks (meter, kilogram, second) is one set, and cgs (centimeter, gram, second) is another. Either measurement is fine, just so long as energy is measured in proper units of Joules (kg m^2 / s^2) if using mks and Ergs (g cm^2 / s^2) if using cgs.

Answer 5

Its a joule. Meter and centimeters are for measuring length,height and width.

Answer 6

Kinetic energy is same as unit of work..meaning it involves force and how much distance the object moved..

KE (kinetic energy) = force * distance

unit of force = newton, lbs
unit of distnce = meters, ft, inch

for SI units (system international)

KE = newton-meter or joules ( 1nm = 1 joule)

Answer 7

Usually, for any kind of energy, you use joules, (or in chemical, calories), and the more standard unit of measure is with meters

Answer 8

Err, no. Force is measured in Newtons. The SI unit of energy is the Joule.

Answer 9

Your answer is simple .
You have 1 input 1 output and the way to take your measurement is to give a name , you can tell it ship or pencil .
But you must prefer to tell it watt , cal or Joule.

Answer 10

Isnt energy measured in Newtons?
