Awagon is accelerating down a hill. which of the following statements are true? a. as the wagon approaches the bottom of the hill, the potential energy decreases and the kinetic energy increases. b. the kinetic energy decreases as the wagon comes towards the bottom of the hill. c. as the wagon approaches the bottom of the hill, the potential energy and the kinetic energy both increase. d. the thermal energy decreases as the wagon comes towards the bottom of the hill.,

As the wagon approaches the bottom of the hill, the potential energy decreases and the kinetic energy increases.

Explanation:

There are two types of energy possessed in the wagon i.e. potential energy and the kinetic energy. As a wagon is accelerating down a hill, its potential energy decreases and the kinetic energy increases.

We know that the energy possessed due to its height above ground level is called its potential energy while the energy possessed due to its motion is called its kinetic energy.

So, the correct option is (A) " As the wagon approaches the bottom of the hill, the potential energy decreases and the kinetic energy increases".
