1
What is terminal Velocity?
When an object gains speed falling down a hill
The point when the velocity and the air resistance even out
When the Air resistance is greater than the object
when an object is floating in space
2
Quantum Physics and Particle Physics are examples of ...
physical science
classical physics
modern physics
motion physics
3
Newton's Third Law of Motion
An object's acceleration depends on the forces acting on it
An object at rest stays at rest
Every action has an opposite and equal reaction
4

Includes magnitude and direction
8
What are collinear points?
Points that lie on the adjacent lines
Points that lie on the same line
Points that lie on the opposite line
Points that lie on planes
9
Physics is…
The science of invisible matter
The science of matter and energy
None of the above
The science of story-telling
10
Newton's Second Law of Motion
An object's acceleration depends on the forces acting on it
Every action has an opposite and equal reaction
An object at rest stays at rest
11
Acceleration is...
... speed and direction.
... a rate of change in velocity.
... speed.
... the gravitational force affecting speed.
12
What is centripetal force?
the motion of an object
the distance an object travels
the speed which an object moves in a circle
a force that causes an object to move in a circle
13
kinetic energy is...
an object has because of the movement of its molecules, and heat
:)
is the energy of mass in motion
in physics, the capacity for doing work

17
What is displacement?
the distance and direction of the objects change in position
the direction of the objects change in positon
something that you put out of place
the distance of the objects change in direction
18
What is gravity?
A force of attraction only between two things that are close
A force of attraction between two things that have weight
A force of attraction between two things that have mass
19
Who was Sir Isaac Newton?
He created the game little big planet
What even is this!!
“Newton developed the theory of gravity, the laws of motion.”
🤷♀️

Vectors
B= Vertical Component.
Rep. as arrow drawn from initial to terminal point.
Component form of a vector is <a,b>. A= horizontal component
Quantity with magnitude and direction.
21
the first law of motion is...
PICK ME PICK ME YOU WILL GET THIS RIGHT
F=MA
for every action there is an equal and opposite reaction
anything at rest stays at rest and anything in motion stays in motion
22
newtons second law of motion states
for every action, there is an equal and oppisite reaction
a object accelertes when a force acts on an object with mass
