Newton's Three Laws of Motion

Question 1

What is a push or pull exerted on an object?

Answer 1

Force

Question 2

What is the force that one surface exerts on another when the two surfaces rub against each other?

Answer 2

Friction

Question 3

What is a unit of measure that equals the force required to accelerate 1 kilogram of mass at 1 meter per second per second?

Answer 3

Newton

Question 4

What is the overall force on an object when all the individual forces acting on it are added together?

Answer 4

Net Force

Question 5

What are forces that produce a nonzero net force, which changes an object’s motion?

Answer 5

Unbalanced Forces

Question 6

What are equal forces acting on an object in opposite directions?

Answer 6

Balanced Forces

Question 7

What is the force that pulls objects toward each other?

Answer 7

Gravity

Question 8

What is the motion of a falling object when the only force acting on it is gravity?

Answer 8

Free Fall

Question 9

What is the force of gravity on an object at the surface of a planet?

Answer 9

Weight

Question 10

What is the friction that acts on objects that are not moving?

Answer 10

Static Friction

Question 11

What is friction that occurs when one solid surface slides over another?

Answer 11

Sliding Friction

Question 12

What is the friction that occurs when an object rolls over a surface?

Answer 12

Rolling Friction

Question 13

What is the friction that occurs as an object moves through a fluid?

Answer 13

Fluid Friction

Question 14

What is the fluid friction experienced by objects falling through the air?

Answer 14

Air Resistance

Question 15

What is the tendency of an object to resist any change in its motion?

Answer 15

Inertia

Question 16

What is Newton’s First Law Of Motion?

Answer 16

An object at rest will remain at rest, and an object moving at a constant velocity will continue moving at a constant velocity, unless it is acted upon by an unbalanced force?

Question 17

What is Newton’s Second Law of Motion?

Answer 17

Acceleration depends on the object’s mass and on the net force acting on the object?

Question 18

What is Newton’s Third Law of Motion?

Answer 18

If one object exerts a force on another object, then the second object exerts a force of equal strength in the opposite direction on the first object.
