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 rests stays at rest UNLESS ACTED UPON BY A NET FORCE.

Answer 2

Newton’s 1st Law

Question 3

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

Answer 3

Inertia

Question 4

The combination of all forces that act on an object.

Answer 4

Net Force

Question 5

Every object exerts a force on every other object. Felt as a pull.

Answer 5

Gravity

Question 6

Amount of matter or “stuff” an object has measured in kilograms. Inertia is related to this.

Answer 6

Mass

Question 7

The force of gravity on your mass; how hard an object is pulled to Earth.

Answer 7

Weight

Question 8

To every action there is an equal and opposite reaction force.

Answer 8

Newton’s 3rd Law

Question 9

Mass on the move! Force required to stop a moving object.

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

Centripital 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 is moving)

Answer 14

Kinetic Friction

Question 15

Force= Mass x Acceleration or F= ma

Answer 15

Newton’s 2nd Law
