Newton's Third Law Vocab

Question 1

Collide/Collision

Answer 1

To strike or hit something with any amount of force.

Question 2

Force

Answer 2

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

Question 3

Motion

Answer 3

The change in an objects position. Its movement.

Question 4

Newton (N)

Answer 4

Unit of measurement for force.

Question 5

Newton’s Law of Action-Reaction

Answer 5

For every action force there is an equal and opposite reaction force. 3rd law of motion

Question 6

Spring Scale

Answer 6

Tool that measures a pulling force by the tension on a spring in units of newton.

Question 7

Mass

Answer 7

A measure of the amount of matter in an object, usually measured in grams.

Question 8

Newton’s First Law of Motion

Answer 8

A body at rest remains at rest, a body in motion continues to move at a constant velocity unless acted upon by external force.

Question 9

Newtons Second Law of Motion

Answer 9

Acceleration is directly proportional to force and inversely proportional to mass.

Question 10

Balanced Force

Answer 10

IF all forces acting on a particular object are balanced so that the net force is “0”, the object will not accelerate.

Question 11

Unbalanced Force

Answer 11

Causes acceleration if one force is not balanced by another force.

Question 12

Contact Force

Answer 12

A force that is applied by objects in contact with each other.

Question 13

Reference Point

Answer 13

A point used to find or describe the location or motion of something.

Question 14

Weight

Answer 14

The force exerted on a mass by gravity, measured in newtons (N).
