What is the formula for speed?
Speed = Distance / Time
100
What is the formula for velocity?
Velocity = Distance / Time with a direction
100
What is the formula for acceleration?
Acceleration = Final Velocity - Initial Velocity / change in time with a direction
100

What is the term for speed at any instant in time?

instantaneous speed

100

What is a change in position called?

motion

200
How is speed different from velocity?
velocity needs a direction
200

What are three ways we can tell if something is accelerating?
speeding up slowing down changing direction
200

What do you call the total distance traveled by an object divided by the total amount of time needed to travel?

average speed

200

What is the difference between the initial position and the final position of an object called?

displacement
