Force and Motion Review

A student wanted to see how his toy car would roll on different types of flooring. He decided to roll the car on a tile floor, a wood floor, and a carpeted floor.

His experiment was designed to test the effects of which of the following forces?

• Gravity and Magnetism

• Gravity

• Magnetism and Friction

• Friction

A teacher attaches pictures to the dry-erase board using tape during a sorting activity. The next day, one of the pictures was found on the ground.

Which force acted upon the picture causing it to fall?

• Magnetism

• Friction

• Evaporation

• Gravity

 Four boxes are lifted straight up from the ground to a shelf. Each box has a different mass, as shown in the table. 

Which box requires the most force to lift it off the ground?

• L

• M

• N

• O

 A student measures the distances traveled by several toy cars in different time periods.

Which car is the fastest? (hint - you will need to find the speed of each car.)

• E

• F

• G

• H

The student wants the red cart to have a smaller increase in its speed than the blue cart when an equal force is applied to both carts. 

What could the student do to one of the carts to achieve this result? 

• Put a bag filled with sand in the red cart only

• Put a bag filled with sand in the blue cart only

• Push the red cart towards the right instead of straight

• Push the red cart towards the left instead of straight

Which force most likely causes the skateboarder to skate down the halfpipe ramp over and over again?

• Gravity

• Magnetism

• Friction

• Pushing

When riding a bicycle, which force mostly likely causes the bicycle to move forward?

• Pulling the pedals

• Gravity pulling the bike down to the ground

• Pushing the pedals

• Magnetism between the wheels and the pedals

Which force most likely explains why skates roll differently on surfaces such as wood, cement, ice, or carpet?

• Gravity

• Pulling

• Friction

• Pushing

The picture shows a row of dominoes.

Which force would most likely cause the row of dominoes to fall?

• Friction

• Push

• Pull

• Manetism

Which investigation will best test the effects of gravity on moving objects?

• Pencils falling from the same height

• Balloons floating upward from the same height

• A ball slowing down on a flat surface

• A bicycle speeding up on a flat surface
