PS.5.2.1 (5.P.1.4) #1: Schoolnet

Macie’s job at the bookstore requires her to move several heavy boxes of books. How can Macie use the least amount of force to move the boxes?

• by packing the books in larger boxes

• by packing the books in smaller boxes

• by stacking the boxes and pulling them out of the storage room

• by stacking the boxes and pushing them out of the storage room

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.

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

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.

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.

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.

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.

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.
