Can kinetic energy be measured

Answer 1

Kinetic energy can be measured, but the act of measuring it changes the kinetic energy of the object you are measuring. For example, you can measure the kinetic energy of a bullet fired from a gun by allowing the bullet to strike an known object and then measure the deflection/deformation of the target object. While it is possible to measure the kinetic energy of the bullet this way, the bullet itself is no longer moving after this measurement, and therefore your measurement caused a change in the bullet's kinetic energy.

.

Kinetic energy (E) can be calculated without changing the kinetic energy of the object under observation if you know the mass (m) of the object and if you can observe or calculate its velocity (v) using the equation E=(1/2)m/v2.

Answer 2

Yes, kinetic energy can be measured. It is calculated using the formula KE = 0.5 * mass * velocity^2, where mass is the object's mass and velocity is its speed in meters per second. The unit of measurement for kinetic energy is joules.

Answer 3

Kinetic energy is measured in (J) Joules. J=Kgm2/S2

Answer 4

I don't know how it is measured but i do know that it is basically movement energy. So if you waved your arm in the air right now, you have 'created' kinetic energy.

hope this helps!
