slide9
This is

the rate of

change of velocity

slide10
What is

acceleration?

slide12
What is

in motion?

slide13
This is

Distance divided by

Time.

slide14
What is

speed?

slide15
A place or object
  • used as a comparison
  • point to tell whether an
  • object is moving is called
  • This.
slide16
What is

A reference

point?

slide17
This is the

Definition of

force

slide18
What is:

A push or a pull?

slide19
A coin resting on a piece of cardboard is placed on a

beaker as shown in the diagram.

When the cardboard is rapidly removed,

the coin drops into the beaker. This is called…

slide20
What is

inertia?

slide21
A ball rolls through

a hollow semicircular tube lying

flat on a horizontal tabletop.

This shows the motion the ball will take

True or false. Fix it if false.

slide22
What is

false?

slide23
Newton’s first

Law states this

slide24
What is

Objects in motion, stay in motion,

And objects at rest, stay at rest

Until acted upon

By an unbalanced force?

slide25
This is the force that

should stop you if the

car stops short.

slide26
What is

The seat belt?

NOT what is your

face hitting the

windshield? -5000 point

slide27
This is the

definition

of inertia

slide28
What is

The tendency of an

object to resist change

In motion?

slide29
A student pushes against a tree
  • with a force of 10 newtons (N).
  • The tree does not move.
  • This is the amount of force
  • exerted by the tree on the student.
slide31
The force of an object, with a certain mass accelerating at a certain rate,
  • can be determined by using the equation below.
  • force = mass X acceleration
  • Of the following obejcts, this object would have the greatest force:
  • a 5-kg object accelerating at 10 m/s2
  • a 5-kg object accelerating at 20 m/s2
  • a 20-kg object accelerating at 4 m/s2
  • a 20-kg object accelerating at 3 m/s2
slide32
What is
  • a 5-kg object
  • accelerating
  • at 20 m/s2?
slide33
This law is why the boy

Has to pull harder on

The big rock to move it.

slide34
What is

Force = mass x acceleration

So If the mass gets larger

The force to pull it

must be larger?

slide35
This is what

North and north

poles do.

slide36
What is

Repel or push

apart?

slide37
Newton’s second

Law relates mass,

force,

and acceleration

In this mathematical

formula.

slide38
What is: F= m x a

Or force equals

mass times

acceleration?

slide39
Forces which are equal

And opposite in direction

move an object in

this direction

slide40
What is

Balanced forces

Don’t move objects ?

slide41
A balloon can be used to

Show

Newton’s third

Law in this diagram.

slide42
What is: for every

Action there

Is an equal and

Opposite reaction

slide43
This is what happens when

A skater pushes another skater

slide44
What is: they both

Go backwards

with equal

And opposite force?

slide45
A student on a skateboard throws

Something heavy. He moves in this direction.

slide46
What is

equal and opposite

to the force of the throw?

slide47
The reason the girl

Fell in the

Water is

described by

this law

slide48
What is

Newton’s third law: for

Every action there is an

Equal and opposite

reaction?

slide49
These are

Two characteristics

That affect the

force of friction.

.

slide50
What are the surface

Textures and how hard

You press them together?

slide51
A balloon and

A bowling ball

Are dropped on the moon.

This is the one that hits first

slide52
What is

They hit at the same time?

slide53
This is what we could add

To reduce

Friction on the

Box sliding up the ramp.

slide54
What are rollers

OR oil

OR wax?

slide55
Friction

Generates this form

Of energy

slide56
What is

heat or thermal?

slide57
These two

Forces affect all

Motion on earth

slide58
What are

Friction and gravity?

slide59
Equal forces

Acting in opposite

directions

Move objects in

This direction

slide60
What is

Balanced forces

Don’t move objects ?

slide67
Acceleration can be

Described as these

three motions

slide68
What is: Acceleration can

be speeding up

Slowing down, or

changing direction?
