energy equations

Question 1

What does an object’s kinetic energy store depend on?

Answer 1

An object’s kinetic energy store depends on only its mass and speed.

Question 2

What is the equation for gravitation potential?

Answer 2

Gravitational potential (J) = mass(kg) x gravitational field strength (N/kg) x height (m)

Question 3

What’s the equation for Kinetic energy?

Answer 3

Kinetic energy (J) = 0.5 x mass(kg) x (speed)squared (m/s)

Question 4

What’s the equation for Power?

Answer 4

Power (w) = work done (J) ÷ time (s)

Question 5

What’s the equation for Elastic potential?

Answer 5

Elastic potential (J) = 0.5 x spring constant (N/m) x (extension) squared (m)
