Speed Acceleration High School

total distance traveled divided by total time taken to travel that distance

• velocity

• motion

• acceleration

• average speed

the rate at which speed or velocity changes

• acceleration

• average speed

• motion

• reference point

What is happening at segment B?

• no motion/object at rest

• constant speed

• acceleration

What is happening at segment A?

• no motion/object at rest

• constant speed

• deceleration

A runner crossed the 1 mile marker of a race running at a speed of 9 miles per hour. She crossed the finish line running at a speed of 9.8 miles per hour. Did the runner change her velocity?

• Yes

• No

• time x distance

• distance x speed

• distance / time

• time / distance
