Which best describes the speed of a ball as it is thrown straight up into

the air and comes back down?

• The ball goes up at a constant speed, stops, then comes down at a

  constant speed.

• The ball goes up at a constant speed, stops, and increases speed as

  it comes down.

• The ball goes slower and slower as it goes up, stops, and then goes faster and faster as it comes down.

• The ball goes slower and slower as it goes up, stops, and then

  comes down at a constant speed.

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.
