5.P.1.4 Practice

John pushed two identical toy cars across the same flat smooth floor. Why did both cars travel the same distance?

• because he pushed the cars at the same time

• because he pushed the cars at different times

• because he applied different forces to the two cars

• because he applied the same force to each of the two cars

Four solid balls, each with a different mass, are moving at the same speed. Which ball would require the most force to stop its motion?

• ball with a mass of 5 kg

• ball with a mass of 10 kg

• ball with a mass of 15 kg

• ball with a mass of 20 kg

How will the force needed to move an object be affected if the mass of the object changes from 100 kilograms to 200 kilograms?

• The force needed to move the object would be tripled.

• The force needed to move the object would be doubled.

• The force needed to move the object would remain the same.

• The force needed to move the object would be reduced by half.

A librarian stacked two identical carts of books. One cart was completely filled, while the second was half-filled. What will happen when the carts are moved?

• Both carts will require the same amount of force to push.

• The cart with the most books will require a greater force to push.

• The cart with the fewest books will require a greater force to push.

• The cart with the most books will require a greater force of gravity to push.

Henry was helping his dad with a project outside. Henry pulled a wagon full of bricks across the yard. He took the bricks out of the wagon to use for their project. Henry then pulled the wagon back across the yard to refill it. Which did Henry most likely observe about the wagon?

• The wagon full of bricks needed more force to be moved because it had less mass.

• The wagon full of bricks needed less force to be moved because it had more mass.

• The empty wagon needed more force to be moved because it had more mass.

• The empty wagon needed less force to be moved because it had less mass.

Mason pushed a cart containing a stack of textbooks and stopped suddenly. Which would most likely happen to the books on the cart?

• The books would slide sideways off of the cart.

• The books would slide off the front of the cart.

• The books would slide off of the back of the cart.

• The books would stay stacked until the cart moves again.

Two objects of different mass are being pushed with an equal amount of force at the same time. Which will most likely occur?

• The object with a greater mass will move farther than the object with less mass.

• The object with less mass will move farther than the object with a greater mass.

• Both objects will move the same distance since the applied force is the same.

• Both objects will move the same distance since their masses are different.

Lacy is pulling a wagon full of rocks. As she sees more rocks, she picks them up and places them in the wagon. Which will most likely happen to the force required to move the wagon?

• The force needed to move the wagon will remain the same.

• The force needed to move the wagon will decrease.

• The force needed to move the wagon will increase.

• The wagon will no longer move.
