Kinetic energy and GPE

what is kinetic energy

energy that an object transfers due to its motion

what two factors determine how much kinetic energy an object has

its speed and mass

the faster/slower an object is moving the more kinetic energy it has

faster

the more/less mass an object has the more kinetic energy it has

more

equation for kinetic energy

½ mv² ( ½ mass x velocity)

what is gravity

a force of attraction between two objects

what two factors affect gravity

mass of the two objects

distance between the objects

what happens when an object comes into a gravitational field

it experiences a force of attraction called weight

what is the equation to work out weight

mass x gravitational field strength

what is the equation for gravitational potential energy

GPE = mgh ( mass x gravitational field strength x height)

as an object rises —— is converted to ——

Kinetic energy is converted to GPE

as an object falls —— is converted to ——

GPE is converted to KE
