Elastic potential energy
100
Newtons 3rd law
What is when a force is exerted an equal force is acting in the opposite direction
100
What is the Formula to calculate Speed??
S= D/T
100
Why do you see a flash of lightning before you hear the thunder?
Light travels much faster through the air than sound does.
200
The energy of motion
What is Kinetic energy
200
An object in motion tends to stay in motion, an object at rest tends to stay at rest
What is inertia
200
the forces acting on a ball thrown into the air?
What is air resistance and gravity
200
Newtons first law
What is Every object retains its state of rest or state of uniform straight line motion unless acted on by an unbalanced force.
200
the term for a solid that converts directly to a gas?
What is sublimation
300
Work done over a period of time
What is Power
300
the attractive force that acts on all objects everywhere
What is gravity
300
The difference between weight and mass
What is Weight is how gravity acts on an object, mass is what makes up the object.
300
What is Terminal Velocity?
When the maximum velocity has been reached by an object falling through a consistent medium.
300
the normal range for human hearing
20-20,000 Hz
400
The unit for work and energy
What is the Joule
400
The equation for force
What is F = ma
400

they hit at the same time
400
What quantity did Newton assume was identical to mass, but we now know also depends upon velocity?
Inertia
400
the electromagnetic spectrum what has the longest WL
What is radio waves
500
If a Car is traveling at 40m/s for 10sec what is the distance it will travel?
D= S x T
D= 40 x 10
D= 400m
500
What is the mass of an object that is traveling at 20m/s^2 and has a force of 10,000N
M = F/A
M= 10,000 / 20
M= 500kg
500
Does your weight increase or decrease on Saturn? Why?
What is Increases, more massive planet= more gravitational pull
500
What does the negative part of this Acc/Time graph show?
The object traveling in reverse

What is Physics the study of?
Physics is the scientific study of matter and energy and how they interact with each other
