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.

For every action there is an equal and opposite reaction.

Question 12

12.

As an elevator accelerates upwards, which force acting on a person inside will be greater?

Tension

Normal

Gravitational

Question 13

13.

As an elevator accelerates upwards, how does your apparent weight change?

Increases

Decreases

Stays the same

Question 14

14.

As an elevator accelerates downwards, which force acting on a person inside will be greater?

Tension

Normal

Gravitational

Question 15

15.

As an elevator accelerates downwards, how does your apparent weight change?

Increases

Decreases

Stays the same
