Force and Motion

Match the word with the correct definition.

• The force that causes objects with mass to attract to one another

• Gravity

• A change in position of an object

• Motion

• A force that, when applied, moves an object away from you

• Friction

• A force that when applied, moves an object towards you

• Pull

• A force that resists (slows down or stops) the motion of two surfaces sliding across one another

• Push

Which of the following is an example of friction?

• An apple falling from the tree.

   

• A ball slowing down on carpet.

• A person seeing themselves in the mirror.

• person pushing a door.

Students are conducting an investigation where they test how the force of magnetism can cause objects to move.

Select all of the objects below that the students would be able to move using the force of magnetism.

A student plays several sports including soccer, baseball, and bowling. Her teacher says throwing the bowling ball requires the most force. Why is this true?

• The bowling ball has the most mass.

• The bowling ball has holes in it.

• The bowling ball has to be held in her hand.

• The balls all require the same amount of force.

Antoina wanted to see how far she could slide a hockey puck 

across different surfaces. She chose to slide the puck across a sidewalk, 

an asphalt road, and the tiled kitchen floor in her house.

Antonia designed this experiment to observe which of the following forces?

• gravity

• friction

• magnetism

• electricity

Students conducted an investigation in which they rolled marbles 

across different surfaces to measure the effect of the force of 

friction on each surface. Friction slows down and stops objects.

Which of the surfaces tested showed the greatest amount of friction?

• Surface A

• Surface B

• Surface C

• Surface D
