Newton's laws of motion

Question 1

Force

Answer 1

A push or a pull exerted on an object in order to change the motion of the object.

Question 2

Motion

Answer 2

A change in position over time.

Question 3

Net Force

Answer 3

The combination of all forces acting on an object.

Question 4

Speed

Answer 4

Distance traveled per rate of time.

Question 5

Velocity

Answer 5

The speed and direction of an object.

Question 6

Acceleration

Answer 6

The rate at which velocity changes over time.

Question 7

Newton’s First Law

Answer 7

An object will remain at rest and an object in motion will remain in motion unless acted upon an outside force.

Question 8

Newton’s Second Law

Answer 8

Force = mass x acceleration.

Question 9

Newton’s Third Law

Answer 9

For every action there is an equal but opposite reaction.

Question 10

Inertia

Answer 10

The tendency of an object to resist being moved or, if the object is moving, to resist a change in speed or direction until an outside force acts on the object.

Question 11

Friction

Answer 11

A force that resists motion.

Question 12

Mass

Answer 12

The amount of matter in an object.

Question 13

Gravity

Answer 13

An attractive force that exists between all objects that have mass.
