Calculating Changes in Energy

Question 1

Kinetic Energy Stored

Answer 1

Ek = 1/2 mv 2 (squared)

Question 2

Gravitational Potential Energy Stored

Answer 2

change in gravitational potential energy=mass×gravitational field strength×change in height

Question 3

Elastic Potential Energy Stored

Answer 3

elastic potential energy= 1/2 ×spring constant×extension (squared)

Ee = 1/2ke(squared)
