New cards

what is kinetic energy

energy stored in moving objects

2
New cards

what do we measure energy in?

Joules (J)

3
New cards

what do we measure mass in

kilograms

4
New cards

what do we measure speed in (v squared)

m/s

5
New cards

what happens when we stetch a spring

we're applying a force to change the length of the spring

6
New cards

define elastic potential energy

energy stored in any compressed or stretched object such as a spring, rubber band, etc.

7
New cards

what do you call the stretch in a spring

extension

8
New cards

what is the spring constant (k) measured in

Newtons per metre (N/m)

9
New cards

what is the extension measured in

Metres (m)

10
New cards

What is gravitational potential energy?

potential energy related to an object's height

11
New cards

what is the gravitational field strength (g) measured in

N/kg
