Lesson 3 Newton's Laws of Motion

Question 1

he action or process of moving or being moved.

Answer 1

motion

Question 2

a basis or standard for evaluation, assessment, or comparison; a criterion.

Answer 2

reference point

Question 3

the rate at which someone or something is able to move or operate.

Answer 3

speed

Question 4

the speed of something in a given direction.

Answer 4

velocity

Question 5

a vehicle’s capacity to gain speed within a short time.

Answer 5

acceleration

Question 6

a tendency to do nothing or to remain unchanged.

Answer 6

inertia

Question 7

the resistance that one surface or object encounters when moving over another.

Answer 7

Friction

Question 8

First Law Of Motion. Isaac Newton’s first law of motion, also known as the law of inertia, states that an object at rest will stay at rest and an object in motion will stay in motion with the same speed and direction unless acted upon by unbalanced force.

Answer 8

Newton’s first law of motion

Question 9

Newton’s second law of motion can be formally stated as follows: 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 9

Newton’s second law of motion

Question 10

Newton’s third law is: For every action, there is an equal and opposite reaction. The statement means that in every interaction, there is a pair of forces acting on the two interacting objects. The size of the forces on the first object equals the size of the force on the second object.
