Newton's Laws of Motion

Question 1

“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.”

Answer 1

Newton’s First Law of Motion

Question 2

“Acceleration depends on the mass of the object and on the net force acting on the object.”

Answer 2

Newton’s Second Law of Motion

Question 3

“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.”

Answer 3

Newton’s Third Law of Motion

Question 4

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

Answer 4

Inertia

Question 5

The rate at which velocity changes

Answer 5

Acceleration

Question 6

The force that one surface exerts on another when the two surfaces rub against each other

Answer 6

Friction

Question 7

The force that pulls objects toward each other

Answer 7

Gravity

Question 8

Forces that produce a nonzero net force, which changes an object’s motion

Answer 8

Unbalanced Force

Question 9

The amount of inertia depends on this

Answer 9

Mass

Question 10

The product of the mass and velocity of an object

Answer 10

Momentum
