Force and Motion Quiz

Makayla is conducting an experiment. She places a large block on the ramp and prepares to time the block as it moves down the ramp. When the block is released, it does not move. Makayla places a piece of wax paper between the block and the ramp. This time the block slides easily down the ramp. Which of the following best explains the job of the wax paper?

• It reduces the force of gravity acting on the block

• It increases the force of gravity acting on the block

• It decreases the friction between the block and the ramp

• It increases the friction between the block and the ramp

Gravity is a force that pulls objects on Earth to the ground. Which picture best shows the force of gravity being overcome?

• Picture A

• Picture B

• Picture C

• Picture D

Kenny is throwing a paper airplane in the air. The wind carries it but eventually it falls to the ground. What force will pull the paper airplane to the ground?

• gravity

• mass

• matter

• friction

Rondell is conducting an experiment on the speed of toy cars. He measures the distance that four toy cars travel and records his data in the table shown.

Which car moves the fastest?

• Blue

• Green

• Red

• Yellow

Tyler hangs a magnet from a string as shown in the picture. He then holds another magnet and moves it toward the magnet on the string.

What will most likely happen to the magnet on the string?

• It will stay in the same position.

• It will break the string

• It will be attracted to the other magnet

• It will repel the other magnet

What is true of the effects of adding mass to the blue wheel's distance traveled?

• Modified Blue Wheel traveled the furthest distance

• Modified Blue Wheel had the least amount of change to its motion

• Original Blue Wheel went a shorter distance

• Original Blue Wheel had no change to its motion

Which type of object would not be attracted to a magnet?

• A Paperclip

• An Opposite Pole on another magnet

• A Pencil

• A Binderclip

What are the two types of forces?

• Push/Pull

• Gravity/Magnetism

• Balanced/Unbalanced

• Conductor/Insulator

Mr. Johnson applied a pulling force on his rolly cart that was loaded with books and it did not move. Why did the cart not move, despite Mr. Johnson's pulling force?

• Mr. Johnson's pulling force was being unbalanced by the other forces affecting the cart

• Mr. Johnson's pulling force was being balanced by the other forces affecting the cart

• Mr. Johnson should've applied a pushing force

• There wasn't enough friction between the cart and the floor.

If Mr. Johnson wanted to make his Rolly Cart easier to move, what could he change?

• Increase the amount of friction between the cart and the floor

• Decrease the mass of the cart by taking some of the books out

• Increase the mass of the cart by adding some books to it

• Increase the size of the cart so it can hold more books
