Energy stores

Question 1

What are the energy stores

Answer 1

Thermal, Kinetic, GPE, Elastic potential, Chemical, Magnetic, electrostatic, nuclear

Question 2

How can energy be transferred?

Answer 2

Mechanically, electrically, by heating or by radiation.

Question 3

What is a mnemonic to remember the energy stores?

Answer 3

Get My Kids Everything They Could Ever Need.

Question 4

Energy lost from GPE store =

Answer 4

= Energy gained in kinetic energy store

Question 5

What is the formula for kinetic energy?

Answer 5

Ek = 1/2mv^2
Ek (J)
mass (kg)
velcoity^2(m/s)^2

Question 6

What is the formula for GPE?

Answer 6

Ep = mgh
Ep (J)
mass(kg)
gravitational field strength (N/Kg)
height (m)

Question 7

How can energy be transferred to the elastic potential energy store?

Answer 7

By stretching or squashing it so long as the limit of proportionality hasn’t been exceeded.

Question 8

What is the formula for elastic potential energy?

Answer 8

Ee = 1/2Ke^2
Ee (J)
K [spring constant (N/m)]
extension^2 (m)
