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.
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.
