Vertical Motion & Projectile Motion — 40-Item Reviewer Worksheet

Emma and Elijah are on the roof of a building. Emma drops Ball A from rest, while Elijah throws Ball B downward at the same time. Which ball hits the ground first?

• Ball A

• Ball B

• Same time

• Depends on mass

David drops a heavy object and a light object from the same height at the same time (no air resistance). What will happen?

• Heavy lands first

• Light lands first

• Land together

• Depends on shape

Jackson throws a ball straight up into the air. At the maximum height of the ball's vertical throw:

• v=0, a=0

• v=0, a=g downward

• v up = a down

• v=0, a upward

Grace kicks a soccer ball at an angle, and it travels through the air as a projectile. For the ball, the horizontal component of velocity:

• Decreases

• Increases

• Constant

• Zero at top

Scarlett is launching water balloons at a target using a slingshot. She wants to know which pair of launch angles will allow her to hit the target at the same distance away, assuming she uses the same speed each time. Which pair of launch angles give the same range?

• 30° and 45°

• 20° and 70°

• 30° and 60°

• 45° and 80°

Emma kicks a soccer ball on level ground. What is the time of flight for the ball?

• v sinθ / g

• 2v sinθ / g

• v cosθ / g

• 2v cosθ / g

Olivia throws a ball straight up into the air. What is the vertical acceleration of the ball while it is in flight?

Maya throws a ball straight up into the air. At the same height while the ball is going up and then coming down, the vertical speeds of the ball are:

• Equal in magnitude, opposite in direction

• Equal and same direction

• Different

• Zero both times

Priya is playing cricket and wants to hit the ball as far as possible. At which angle should she hit the ball to achieve the maximum range?
