Force Week 3 - Acceleration Explore

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.

• The force of gravity acting on the kickball is greater.

Why would you need more force when riding a bike up a hill than down a hill?

• The mass of a bicycle is less when riding up a hill.

• The mass of a bicycle is greater when riding up a hill.

• More force is needed to keep a bike going up a hill while gravity is pulling it down the hill.

Two cars, a heavier car and lighter car, are pushed with equal force, and are affected by the same amount of friction.

Which best describes the effect on the distance the cars will

move?

• The lighter car will travel a longer distance because it has more mass.

• The heavier car will travel a shorter distance because it has more mass.

• The lighter car will travel a shorter distance because its wheels will roll more quickly.

• The heavier car will travel a longer distance because its wheels will roll more slowly.
