1.5 kinetic energy and elastic energy stores

Question 1

How does an object affect the kinetic energy store?

Answer 1

the kinetic energy store of a moving object depends on its mass and its speed

Question 2

What is the calculation for the kinetic energy store of an object?

Answer 2

Ek = 1/2 mv2

Question 3

What is elastic potential energy?

Answer 3

Elastic potential energy is the energy stored in an elastic object during work is done on the object

Question 4

What is the calculation for the elastic potential energy stored in a stretched spring?

Answer 4

Ee = 1/2 ke2

Question 5

What does Ek stand for?

Answer 5

Kinetic energy ( j )

Question 6

What does M stand for?

Answer 6

Mass (kilograms, kg)

Question 7

What does v2 stand for?

Answer 7

Speed2 (meters per second, m/s)2

Question 8

What does Ee stand for?

Answer 8

Elastic potential energy (joules, j)

Question 9

What does K stand for?

Answer 9

Spring constant (newtons per metre, N/m)

Question 10

What does e2 stand for?

Answer 10

Extension2 (metres, M)2

Question 11

What is the equation for hook law?

Answer 11

F= k x e (K is the spring constant)

Question 12

What is the spring constant?

Answer 12

A measure of how stiff the spring or material is
