Question
What can you say about the kinetic energy of the two bodies shown below when both have the same speed?
- KEA > KEB
- KEA < KEB
- KEA = KEB
- KEA ≥ KEB
Hint:
KEA<KEB
The correct answer is: KEA < KEB
Kinetic energy is directly proportional to the mass of an object and the square of its velocity.
If velocity remains constant, kinetic energy will be greater for the object which has more mass, then the object which has less mass.
