Newton's Laws

Question 1

Define Force

Answer 1

A push or pull on an object

Question 2

Define Acceleration

Answer 2

the rate of change of velocity

Question 3

Define Inertia

Answer 3

the ability of an object to resist change in motion

Question 4

Define Velocity

Answer 4

the speed of an object

Question 5

What does Newton’s First Law state?

Answer 5

All objects in motion stay in motion and all objects that are at rest stay in rest.

Question 6

What does Newton’s Second Law state?

Answer 6

Force equalls Mass times Acceleration. F = M x A

Question 7

What does Newton’s Third Law state?

Answer 7

Every action has an equal and opposite reaction.

Question 8

How are Velocity and Acceleration related to each other?

Answer 8

velocity is the mesure of the displacement of an object (its speed), and acceleration is the rate of change of velocity

Question 20

Match each phrase with the correct Newton’s Law

Question 23

what is a collision

Answer 23

when 2 or more objects hit each other

Question 24

During a collision, what can change in the objects involved

Answer 24

their shape and size

Question 25

what causes changes in motion and shape of colliding objects

Answer 25

small imperfections in the atomic structure

Question 26

what is transferred during a collsion

Answer 26

energy

Question 27

is it possible that when an object pushes on another in a collision, it may not appear to change shape when it is actually doing so, but just at a scale that is too hard for us to see?

Answer 27

yes

Question 28

what happens to solid objects in a collision or when other contact forces are applied to them

Answer 28

they bend and sometimes break

Question 29

if a moving object collides with a motionless object, why does the motionless object begin to move

Answer 29

because energy is transferred
