Lesson 3 Newton's Law of Motion pg. 44-67

Question 1

the 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

Inertia is the tendency of an object to remain at rest or in motion. Newton’s First Law of Motion states that an object will remain at rest or move at a constant speed in a straight line unless it is acted on by an unbalanced force.

Answer 7

Law of Inertia

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

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

Question 10

A force is a push or a pull that acts upon an object as a results of its interaction with another object. … These two forces are called action and reaction forces and are the subject of Newton’s third law of motion. Formally stated, Newton’s third law is: For every action, there is an equal and opposite reaction.
