Car A is parked on a hill and Car B is driving down a level highway. Which statement best describes the two cars? A) Car A has kinetic energy and Car B has kinetic energy. B) Car A has potential energy and Car B has kinetic energy. C) Car A has kinetic energy and Car B has potential energy. D) Car A has potential energy and Car B has potential energy.

Respuesta :

Kinetic energy is energy in motion,while potential energy is energy at rest. 

Car A is parked, so it consists of potential energy. 
Car B is driving, so its in motion, (kinetic energy). 

Answer: B) Car A has potential energy and Car B has kinetic energy.


To solve the problem we must know about Potential and kinetic energy.

What is Potential Energy?

Potential energy is defined as the energy stored on the object which is relative to its position.

For example, the potential energy of a steel ball at a particular height is more than the steel ball at the ground.

What is Kinetic Energy?

It is the type of energy an object has due to its motion. it is directly proportional to the product of mass and the square of the velocity of the object.

Car A has potential energy and Car B has kinetic energy.

Comparing Car A and Car B?

Now, as Car A is parked on a hill, therefore, it is in a stationary condition. thus, Car A will have potential energy. while as the Car B is moving downward, therefore, will have motion, thus, Car B will have kinetic energy.

Hence, Car A has potential energy and Car B has kinetic energy.
