As a roller coaster goes downhill a) kinetic energy is converted into potential energy. b) potential energy is converted into kinetic energy. c) electrical energy is converted into potential energy. d) potential energy is converted into electrical energy.

Answer is B

Explanation:

Potential is when the energy is stopped kinetic is when it’s in motionAt the top of the hip it’s stopped. POTENTIAL ENERGYWhile going down the hill is KINETIC

The correct answer is "potential energy is converted into kinetic energy".

Explanation:

Kinetic energy: Kinetic energy is the energy due to the motion of the object.

The expression for the kinetic energy is as follows;

Here, M is the mass of the object and v is the speed of the object.

Potential energy: Potential energy is the energy possessed due to the position.

The expression for the potential energy is as follows;

PE= mgh

Here, m is the mass of the object, g is the acceleration due to gravity and h is height.

In the given problem, a roller coaster goes down. At maximum height, the roller coaster have maximum potential energy due to height. When it comes down then the potential energy gets converted into kinetic energy.

The speed of the roller increases when it comes down. The kinetic energy of roller coaster also increases.

Therefore, the correct option is (B).
