Big Idea 13, 1, & 2 Assessment

Brian and Emily are testing different paper airplane designs to see which will allow a plane to travel the farthest distance. 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 falls 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 paperclip.

• 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.

Julio and Tammy are moving a dresser. They are arguing about which direction to move it. Julio is pushing the dresser with a force of 5 Newtons towards Tammy. Tammy is pushing the dresser towards Julio with a force of 10 Newtons. What happens to the dresser due to the forces applied?

• The dresser does not move.

• The dresser moves towards Julio.

• The dresser moves towards Tammy.

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

Some mornings Marcie rides in her mother’s car to school, and other mornings she rides in her father’s car. Marcie noticed that when she rides in her mother’s car, it takes less time to travel the same distance as when she is in her father’s car. Based on the information above, which of the following statements is true?

• Her mother's car is traveling at a greater speed than her father's car.

• Her father's car is traveling at a greater speed than her mother's car.

• Both cars are traveling at the same speed since they travel the same distance.

• Both cars accelerate at the same rate, but her mother's car has a greater mass.

Magnets have a north and south pole. What happens if you try to touch the north and south ends of two magnets together?

• The north and south poles will repel each other.

• The north and south poles will be attracted to each other.

• The north and south poles will neither attract nor repel each other.

• The north and south poles will create gravity and attract other objects.

The force of gravity appears to attract all objects equally, regardless of mass. Which of the following demonstrates this idea?

• Two cars traveling along the road at the same speed in opposite directions.

• A rubber ball will bounce much higher than a wooden ball, even if they weigh the same.

• Magnets can both repel and attract each other, depending on how they come into contact.

• A bowling ball and a marble will fall to the ground at the same rate when someone drops them.

Peter is playing tug of war with Michael. They both understand that to win the game of tug of war, one player must pull the flag over their opponent's line, but during this game, the flag tied to the center of the rope is not moving. What is happening to the rope in this example?

• Peter is applying more force in one direction.

• Michael is applying more force in one direction.

• Peter and Michael are applying equal forces in the same direction.

• Peter and Michael are applying equal forces in opposite directions.

Ruth tried to pound a large nail into a board using a small hammer. Partway into the board, the nail stopped. Ruth switched to using a heavier hammer, and the nail went into the board easily. Why did the larger hammer work?

• The nail could not push the larger hammer out of the way.

• B. The larger hammer had less mass, so it exerted more force.

• C. There is more friction between a large hammer and the nail.

• D. The larger hammer had more mass, so it exerted more force.

Tameika’s mom parked their car on the road. Tameika ran from the car to the house. Which statement is true about Tameika’s movement?

• Tameika changed direction but did not change position.

• Tameika’s speed was the same throughout the movement.

• Tameika changed position and may have changed direction.

• Tameika’s position was the same throughout the movement.

Noah is playing with a soccer ball at the top of a hill. Noah 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.

A teacher writes the following note on a student’s experimental design: “You did not identify a control group.” Why is it important to identify a control group?

• A scientist must form a prediction to see if their results are valid.

• A scientist must know which variable to use for making a model.

• A scientist must observe data to make a conclusion based on evidence.

• A scientist must know what normally occurs so they can compare this to what they are testing.
