Force and Motion

Below is a distance time graph that shows the motion of a student on a walk. Which statement best describes the students' motion?

• The student walks slowly at first, then increases their speed, stops and very quickly returns to the starting point.

• The student walks up a hill at the beginning, and then has a flat surface, and then walks down a hill at the end

• The student is going faster and faster in the last two minutes

• The student starts out moving very fast, slows down in the middle of the walk, and then speeds up again at the end

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 witht he 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.
