Brain and Emily are testing different paper airplane designs to see which will allow a plane to go the farthest. Emily folds her plane and attaches a paperclip to the front of it. After she throws the plane, it travels about fifty feet and then starts to fall to the ground. Why does the plane eventually fall to the ground?

• The force of air resistance stops acting on the plane

• The plane was not designed to carry a load like the paper clip

• The force of gravity is greater than the forces keeping the plane in the air

• The paperclip creates a magnetic force that attracts the plane to the ground

Aaron is playing with a soccer ball at the top of a hill. Aaron kicks the ball and it rolls down the hill. Which of the following best describes what happens as the ball rolls?

• The force of gravity pulls the ball downhill

• The force of friction causes the ball to roll faster down the hill

• The force of gravity is balanced by air resistance acting on the ball

• The force of friction is greater than the force of gravity acting on the ball

While Carmen is at the park with her family, she walks up to a wishing well. She throws a penny down the well, and she hears a splash at the bottom. Which of the following best describes what happens as the penny falls?

• The force of gravity is equal to the air resistance acting on the penny

• The magnetic force of the well attracts the penny and causes it to fall even faster

• The force of friction acts against air resistance, causing the penny to fall even faster

• The force of air resistance acts against gravity, but it is not enough to overcome gravity

Which of the following explains why a parachute makes a person falling from a great height fall more slowly?

• The parachute reduces the friction in the air

• The parachute pulls upward, so the fall is slower

• The parachute causes air resistance, which slows the fall

• The parachute increases the pull of gravity on the person wearing it

David and Peter are moving a bookshelf across the thick carpet in their classroom. Even though they push as hard as they can, the bookshelf only moves a few inches at a time. Which of the following best explains what happens as they push the bookshelf?

• The force of gravity helps the motion of the bookshelf

• The force of friction opposes the motion of the bookshelf

• When they try to push the bookshelf, air resistance acts against them

• When they push the bookshelf, the bookshelf pushes back with an equal and opposite force

While on a camping trip, Shane and Katie are traveling in a boat on a river. On their trip, the river's current carries them down the river at a speed of 5 meters per second (m/s). They do not need to row because the current is carrying them in the direction they need to go. If Shane and Katie decided to add force by rowing the boat with the current, which of these statements would best describe the motion of the boat?

• It would speed up

• It would slow down

• It would stay the same

• It would move in the opposite direction

Will and Tammy are moving a dresser. They are arguing about which direction to move it. While Will is pushing the dresser with a force of 5 Newtons (N) towards Tammy, Tammy is pushing the dresser towards Will with a force of 10 Newtons (N). What happens to the dresser?

• The dresser does not move

• The dresser moves towards Will

• The dresser moves towards Tammy

• The dresser moves towards Tammy, then back towards Will.

Candice is rearranging the furniture in her room. She has two different dressers that are the same size. When she pushes on each dresser, she finds that it is harder to move Dresser A than it is to move Dresser B. Which of the following best explains why Candice will have to push Dresser A with more force than Dresser B?

• Dresser A has more volume than Dresser B

• Dresser A has less volume than Dresser B

• Dresser A has more mass than Dresser B

• Dresser A has less mass than Dresser B

Caleb pushes a box on the floor and makes the box move. Which of the following is the best way to make the box move farther?

• Increase the mass of a box

• Push on the box with more force

• Push the box in a different direction

• Add texture to the bottom of the box to increase the amount of friction
