Q. 135.0( 1 Vote )

Write true or false for the following statements :

If we know the speed and mass of an object we can find out its kinetic energy.

Answer :

True

Explanation: Kinetic energy KE of a body of mass m moving with velocity or speed v is given by the formula:


KE = m v2


The formula suggests that kinetic energy depends on mass and speed of the object.


So if we know the speed v and mass m of an object we can find out its kinetic energy.
