how fast you change position

• m/s
• requires a relative position
• speed = rate times time

total distance (m)/ total time = m/s + direction

• different from speed due to direction
• north, south, east, west
• m/s

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

velocity (m/s + direction)/ total time + m/s(squared) =meters per second/per second

• change in velocity over time
• negative = decrease
• positive = increase

when you slow down

• 5 m/s/s
• speed
• helped by friction

amount of matter in an object

• kg
• never changes
• confused with weight

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

mass x velocity

• kgm/s
• velocity
• change

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

• speed
• acceleration
• change

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
