Unit 1 Lesson 3 - Newton's Laws of Motion

Question 1

an object that appears to stay in place

Answer 1

reference point

Question 2

a measure of the distance an object moves in a given amount of time

Answer 2

speed

Question 3

change in an object’s position over time

Answer 3

motion

Question 4

a quantity that describes the speed of the object and its direction of travel

Answer 4

velocity

Question 5

the rate at which velocity changes

Answer 5

acceleration

Question 6

the tendency of objects to resist any change in motion

Answer 6

inertia

Question 7

An object at rest stays at rest and an object in motion stays in motion with the same speed in the same direction unless acted upon an unbalanced force

Answer 7

Newton’s First Law of Motion

Question 8

The acceleration of an object as produced by a net force is directly proportional to the magnitude of the net force, in the same direction as the net force and inversely proportional to the mass of the object

Answer 8

Newton’s Second Law of Motion

Question 9

For every action, there is an equal and opposite reaction

Answer 9

Newton’s Third Law of Motion

Question 10

Newton’s First Law of Motion

Answer 10

law of inertia
