Question 1

1.

A magician pulls a tablecloth out from under dishes and glasses on a table without disturbing them.

Question 2

2.

A person’s body is thrown outward as a car rounds a curve on a highway.

Question 3

3.

Rockets are launched into space using jet propulsion where exhaust accelerates out from the rocket and the rocket accelerates in an opposite direction.

Question 4

4.

A picture is hanging on a wall and does not move.

Question 5

5.

A person not wearing a seatbelt flies through a car window when someone slams on the breaks because the person’s body wants to remain in continuous motion even when the car stops.

Question 6

6.

Pushing a child on a swing is easier than pushing an adult on the same swing, because the adult has more inertia.

Question 7

7.

Acceleration is produced when a force acts on a mass. The greater the mass (of the object being accelerated) the greater the amount of force needed (to accelerate the object).

Question 8

8.

An object at rest will remain at rest unless acted on by an unbalanced force. An object in motion continues in motion with the same speed and in the same direction unless acted upon by an unbalanced force

Question 9

9.

This law is often called "the law of inertia."

Question 10

10.

A soccer ball accelerates more than a bowling ball when thrown with the same force.

Question 11

11.

A student leaves a pencil on a desk and the pencil stays in the same spot until another student picks it up.

Question 12

12.

Two students are in a baseball game. The first student hits a ball very hard and it has a greater acceleration than the second student who bunts the ball lightly.

Question 13

13.

For every action there is an equal and opposite reaction.

Question 14

14.

The swimmer moves her hand down and to the left and her body goes forward to the right.

Question 15

15.

A rocket is sent into space. When the power dies out, the rocket will just keep floating and moving in space forever (unless an unbalanced force, such as a meteor, runs into it).
