Question Question 12
Two toy cars A and B of masses 500 g and 200 g respectively are moving with the same speed. Which of the two has greater kinetic energy?
The toy car A has greater kinetic energy than toy car B.
Reason — The two toy cars A and B are moving with the same speed. As the toy car A has greater mass (500 g) than toy car B (200 g) hence its kinetic energy is also greater.
