True 

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

KE = \(\frac{1}{2}\)mv

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.
