what is kinetic energy
energy stored in moving objects
what do we measure energy in?
Joules (J)
what do we measure mass in
kilograms
what do we measure speed in (v squared)
m/s
what happens when we stetch a spring
we're applying a force to change the length of the spring
define elastic potential energy
energy stored in any compressed or stretched object such as a spring, rubber band, etc.
what do you call the stretch in a spring
extension
what is the spring constant (k) measured in
Newtons per metre (N/m)
what is the extension measured in
Metres (m)
What is gravitational potential energy?
potential energy related to an object's height
what is the gravitational field strength (g) measured in
N/kg
