Question

Starts from rest on a plane road. What are the possible energy changes taking place while the truck is in motion?

Answer 1

Answer:

The kinetic Energy is possible to change. but the potential energy will remain constant.

Explanation:

Due to the friction between road and wheels of the truck. The velocity of the truck will change. Hence the Kinetic energy will also change. (because Kinetic energy is proportional to the square of velocity)

As long as the truck is going in the same level without any elevation or going down a slope. The potential energy will remain same. (because Potential energy due to gravitational force is proportional to height)
