Question

9As a student walks downhill at constant speed, his gravitational potential energy

(1) increases and his kinetic energy increases

(2) increases and his kinetic energy remains the

same

(3) decreases and his kinetic energy increases

(4) decreases and his kinetic energy remains the

same

Answer 1

As a student walks downhill at constant speed, his gravitational potential energy: 4. decreases and his kinetic energy remains the same.

What is gravitational potential energy?

Gravitational potential energy (GPE) can be defined as a type of energy possessed by an object due to its height above the Earth surface.

In Science, the gravitational potential energy of an individual such as a student is highly dependent on his or her height and the acceleration due to gravity.

What is kinetic energy?

Kinetic energy can be defined as a type of energy possessed by an object or body due to its motion or speed.

This ultimately implies that, a student in motion or moving with speed would possess kinetic energy.

In conclusion, the gravitational potential energy of a student decreases as he walks downhill at constant speed while his kinetic energy remains the same.
