Forces

Question 1

A push or a pull one body exerts on another.

Answer 1

Force

Question 2

An object moving at a constant velocity keeps moving at that velocity an object at rest stays at rest (unless acted upon a net force).

Answer 2

Newton’s First Law

Question 3

The tendency of an object to resist any change in motion.

Answer 3

Inertia

Question 4

Combination of all forces that act on an object.

Answer 4

Net Force

Question 5

Every object exerts a force on every other object - pull.

Answer 5

Gravity

Question 6

Amount of “stuff” that makes up you (kilograms).

Answer 6

Mass

Question 7

Force of gravity on your mass.

Answer 7

Weight

Question 8

To every reaction there is an equal and opposite reaction.

Answer 8

Newton’s Third Law of Motion

Question 9

Mass on the move.

Answer 9

Momentum

Question 10

Anything that’s thrown or shot through air.

Answer 10

Projectile

Question 11

Force acting toward the center of a curved or circular path.

Answer 11

Centripetal Force

Question 12

Opposes motion between two surfaces that are touching each other.

Answer 12

Friction

Question 13

Resists getting an object moving (this is when objects are not moving).

Answer 13

Static Friction

Question 14

Resists keeping an object moving (happens while it’s moving).

Answer 14

Kinetic Friction

Question 15
