Force and Motion Review

Carey left a bowling ball and kickball outside on a windy day. Which best explains why the kickball moved but the bowling ball did not?

• The kickball has less mass so it was easier to move. 
• The force of gravity acting on the bowling ball is greater 
• The mass of the kickball is greater so it is easier to move

Don throws a ball in the air. The ball comes back to the ground because

• the wind pushes on the ball with friction 
• the mass of Earth creates a pull of gravity on the ball 
• the core of Earth pulls on the ball with a magnetic attraction 
• the weight of the atmosphere pushes down on the ball
