You are told 3 things…1. That there are two objects with equal masses. 2. Both objects are in motion. 3. One object has a greater kinetic energy than the other. How is this possible?

Question

A. One object has a greater volume than the other object

B. One object is blue and one object is red

C. One object has a greater density then the other object

D. One object has a greater speed than the other object

Answer 1

D. One object has a greater speed than the other object.

Kinetic energy depends on both mass and speed. If two objects have equal masses, but one has a greater speed, it will have a greater kinetic energy.
