B 500

What two components does velocity have?

C 100

• Speed

• Direction

Place A Wager

C 400

You are on an airplane traveling 300 miles/hour

west. The wind that you are flying through has a velocity of 100 miles/hour east. What

is your velocity?

200 miles/hour WEST

C 400

current of the river is moving at 20 m/s downstream. What

is your overall velocity?

C 500

5 m/s downstream

C 500

This is defined as a change in velocity.

D 100

Acceleration

D 100

A merry-go-round is traveling at a constant speed of 2 m/s. Is the

merry-go-round accelerating?

D 200

YES

D 200

D 300

Acceleration refers to what three things?

1) Increasing speed

2) Decreasing speed

3) Change of direction

D 300

Is the moon accelerating?

Explain

D 400

YES. Even though it is moving at a constant speed, it is moving in a circular path so it is always

changing direction.

D 400

Assuming that each cyclist did not change direction during the race, which

cyclist had no acceleration?
