Analyze the data in Table 1 below. What question was the scientist that collected this data trying to answer?

• Does the shape of the magnet affect the strength of the force the magnet has on the object?

• Does the distance a magnet is away from an object affect the force the magnet has on the object?

• Does the size of the magnet affect the strength of the force the magnet has on the object?

What cause and effect relationship can you infer by looking at Table 1 below?

• The distance from the magnet makes no difference in the amount of force the magnet has.

• The farther the object is from the magnet, the stronger the force is.

• The closer the object is from the magnet, the stronger the force is.

To move the heavy box shown, Kylie and her friends lifted it onto a cart with wheels. Why was it easier to move the box by placing it on wheels than by sliding it?

• There was less mass.

• There was less friction.

• There was less density.

• There was less gravity.

A ball is sitting loose on a flat wagon that is going in the direction of the arrow. If the wagon suddenly stops, the ball will

• also suddenly stop

• roll forward in the wagon towards the handle

• roll backward in the wagon away from the handle

• bounce up and down

You are pushing a box. The force is shown with an arrow. The box does not move. What keeps the box from moving even though you are pushing on it?

• You are pushing the box in the wrong direction.

• There is too much air resistance to move the box.

• The force of friction is opposing the force you exert.

• The force of gravity is opposing the force you exert.

Felipe and Marsha were studying friction and decided to do an experiment. They place four equally sized blocks made of different materials on an elevated plastic tray. They watched the blocks move down the tray. Which block would experience the least amount of friction as it moved down the tray?

• ice block

• sponge block

• sandpaper block

• plastic block

Ben put different masses on each of the carts. He then launched each cart from the same starting point using the same amount of force. Ben measured how far each cart rolled from the starting point.How will the force of the launch affect the carts?

• Cart 3 will travel the longest distance.

• Cart 1 will travel the shortest distance.

• Cart 3 will have the least change in its motion.

• Cart 1 will have the greatest change in its motion.
