A push or pull applied to an object
When two or more forces act on an object at the same time
7
Define Force
Information that supports an idea
A force that causes objects with mass to attract each other
Any large celestial bodies that revolve around the Sun
A push or pull that causes an object to move, stop, or change direction
8
What is the formula for Force?
Force = Mass×Acceleraton
Force = Acceleration×Illuminati
Force = Acceleration×Velocity
Force = Velocity×Temperature
9
this is a unbalanced force
False
True
10
Define acceleration
change in position over a period of time
speed with direction
location
Change in velocity over a period of time
11
Which is an example of Newton's Third Law?
A bird sneezes, so a hurricane occurs
A stool is pushed over, so there is a loud crash
A ball is kicked, so it rolls
A soda is opened, so it fizzes
12

350 km/h
50 km/h
35 km/h
100 km/h
13

C
A
B
D
14
Which is an example of Newton's first law of motion?
It is easier to push an empty shopping cart because it has less mass
If you kicked a soccer ball into space, it would keep going forever
15

Third Law
First Law
Second Law
16

Black Line
Neither Line
Both Lines
Red Line
17
Whats net force
The sum of all forces together
one force
penguins sing and talk doNT TEST ME
theycandanceTHEYCANDANCE
18
What is an unbalanced force
Forces that are equal
How cloe locked her locker
How Madison ate a teacher
Forces that are unequal
19
Is this force balanced or unbalanced?
Unbalanced
Balanced
20
Balanced force
are
forces that act against each other &do not cause a change
force that pulls magnets and metals together
a force that attracts any object with mass
forces that are unequal in size/direction & cause change
21
Nate drove for 11 hours at a constant rate of speed of 55 mph. How far did he travel?
605 miles
550 miles
0.2 miles
5 miles
22
Define Velocity:
The rate of change in direction, scalar quantity
Vector? Scalar? Displacement? Fancy science words
The rate of change of displacement, vector quantity
The rate of change in time, scalar quantity
23
Newton's 2nd law was also known as ____
inertia
F=m(a)
pick me
Action -reaction
24
What is inertia?
force that acts between materials
Friction
property of a body to resist change to its state of motion
Newton's first law
25
Newton's second law states...
Acceleration causes an object to speed up
For every action, there is an equal and opposite reaction
An object will remain at rest unless acted upon by another force
Acceleraton depends on the forces acting on an object
26
Newton's 3rd law was also known as the law of _____
Action-reaction
all 3 of them
inertia
F=m(a)
27
Newton's First Law states...
Objects never move.
Inertia is a main force.
For every action there is an equal and opposite reaction.
Objects at rest or in motion only change with greater force.
28
Define Motion.
When an object changes position relative to reference point
Moving from one place to another
Speed
How far an object traveled
29
Inertia is the resistance....
an object compared to its origin.
an object because of its interaction
of any physical object
an object has moved from its original position.
30
what is inertia??
a group of particles that combine\ to make force
the same thing as gravity
none of the above
a tendency to do nothing or to remain unchanged
31
Which is an example of Newton's third law of motion?
A boat with more stuff in it will have more acceleration
A car will stay still until a force acts upon it
When you release the air out of a balloon, it flies the opposite way
32

All of the above
negative slope
33

C
B
A
34
The greater mass, the greater the?
Birds

35
is this a balanced force?
False
True
36
Newton's Third Law states...
For every action, there is a larger reaction.
Every action is caused by force.
For every action, there is an equal and opposite reaction.
For every action, there is a smaller reaction.

Newton's second law can be shown with this equation:
Force = Acceleration x Mass ( F = A x M )
Force = Mass X Acceleration ( F = M x A )
Anger = Mr. Grooms X Fire ( A = M x F )
Mass = Force / Newtons ( M = F/N )
