Term

Definition
how fast you change position  m/s
 requires a relative position
 speed = rate times time



Term

Definition
total distance (m)/ total time = m/s + direction  different from speed due to direction
 north, south, east, west
 m/s



Term

Definition
total distance (m) / total time (s) = m/s  the average rate at which an object covers a distance
 most objects don't move in a constant speed.
 m/s



Term

Definition
velocity (m/s + direction)/ total time + m/s(squared) =meters per second/per second  change in velocity over time
 negative = decrease
 positive = increase



Term

Definition
when you slow down  5 m/s/s
 speed
 helped by friction



Term

Definition
amount of matter in an object  kg
 never changes
 confused with weight



Term

Definition
a measure of how much an object resists a change in its motion  Newton's Third Law
 change in velocity
 objects at rest will stay in rest unless acted on by another force



Term

Definition


Term

Definition
how far and in what direction an object an object has moved from its starting point 


Term
law of conservation of momentum 

Definition
when two objects collide, the total momentum before the collision is the same as the total momentum after the collison is the smae as the total momentum after the collision.  transfer
 nothing lost
 total amount
