Speed, velocity, acceleration

Motion is

• the distance traveled divided by the time it takes to travel that distance

• when an object changes position over time relative to a reference point

• a change in velocity over time

• the object that appears to stay in place

A reference point is

• a point that moves through space

• when a person sees another object moving past it

• the object that appears to stay in place

• the change in velocity

Speed

• the distance traveled divided by the time that it takes to travel that distance

• the time that it takes to travel a distance

• the time that it takes an object to travel divided by the distance travelled

• the distance traveled times the time it takes to travel that distance

Velocity is

• the same as speed

• the rate in which speed changes over time

• the object that appears to stay still

• the speed of an object in a particular direction

Acceleration is

• the speed of an object in a particular direction

• the distance traveled divided by the time that it takes to travel that distance

• the change in speed over time

• the rate at which velocity changes over time
