objects will stay in motion unless force changes there motion
what is mass
space taken by an object
what is a newton
a measure of force
what is acceleration
a rate at which an objects velocity changes over time
unbalanced force=
change in speed=acceleration
what is pound
how we measure weight
what is kinetic energy
moving energy
what is velocity
speed in a given direction
what is weight
amount of force put on by gravity
stored energy
