potential and kinetic energy

Question 1

WHAT IS GRAVITATIONAL POTENTIAL ENERGY?

Answer 1

Energy stored in objects above the Earth’s surface.

Question 2

EXAMPLE OF GPE?

Answer 2

A diver on a diving board, a bird on the branch of a tree and a flying plane all possess gravitational potential energy.

Question 3

WHAT IS THE RELATIONSHIP BETWEEN HEIGHT AND THE GPE OF AN OBJECT?

Answer 3

An object gains more potential energy as it is raised higher above the Earth’s surface.

Question 4

WHAT IS THE RELATIONSHIP BETWEEN GPE AND THE MASS OF AN OBJECT?

Answer 4

Objects with more mass have more GPE.

Question 5

WHAT IS KINETIC ENERGY?

Answer 5

Objects with more mass have more GPE.

Question 6

EXAMPLE OF KE

Answer 6

A person running, a flying plane and vibrating guitar strings all possess kinetic energy.

Question 7

WHAT IS THE RELATIONSHIP BETWEEN KINETIC ENERGY AND VELOCITY?

Answer 7

Objects with a larger mass have more kinetic energy.
