8.6 C Laws of Force and Motion

Question 1

An object at rest stays at rest or an object in motion stays in motion until unbalanced forces act upon it. This is often referred to as Newton’s First Law of Motion.

Answer 1

Newton’s Law of Inertia

Question 2

The tendency of a physical object to remain sill or continue moving unless force is applied

Answer 2

Inertia

Question 3

The state of an object when it is not in motion.

Answer 3

At Rest

Question 4

Forces on an object that cause change in the motion of the object.

Answer 4

Unbalanced Forces

Question 5

Acceleration of an object depends on the object’s mass and magnitude of the force acting upon it (F=ma) is often referred to as Newton’s Second Law of Motion.

Answer 5

Newton’s Law of of Force and ACCELERATION

Question 6

A push or pull that can change the motion of an object

Answer 6

Force

Question 7

A number describing the size or quantity of something.

Answer 7

Magnitude

Question 8

Change of an object’s speed or direction.

Answer 8

Acceleration

Question 9

Newton’s law that states that for every action there is an equal and opposite reaction is often referred to as Newton’s Third Law of Motion.

Answer 9

Newton’s Law of Action-REACTION

Question 10

Force exerted on another object.

Answer 10

Action

Question 11

Resistance or force of equal magnitude action in the opposite direction to an action force.

Answer 11

Reaction
