What is Potential Energy?
Potential Energy is the energy you or something has at the top of a hill.
100
What is the formula for GPE?
GPE= mass x 9.8 m/s x height
100
What is Newton's First Law?
An object in motion tends to stay in motion
100
What is the freezing point of water in C?
0 degrees C
100
What is the unit for GPE?
Joules
200
Label a rollercoaster with the words, Potential energy, kinetic energy, and
GPE GPE KE KE
200
What is the Acceleration formula?
Acceleration= (final velocity- initial velocity)/ time
200
What is the melting point of water in C?
0 degrees C
200
What is the units for power?
Watts
300
Give an example of KE and GPE. But not a rollercoaster
bouncing ball
300
What is the work formula?
Work= force x distance
300
What is Newton's second law?
The acceleration of an object is directly related to the force of an object.
300
What is the boiling point of water in F?
212 degrees F
300
What is the unit for acceleration?
(m/s)2
400
What is the formula for KE?
KE= 1/2 x mass x (velocity)2
400
What is Newton's third law?
For every action force, there is an equal and opposite reaction force
400
What are the three phase changes of water?
Solid, liquid, or gas
400
What is velocity units?
m/s
500
What is kinetic energy?
Kinetic energy is where you have GPE at the top of a hill then you start to go down and it changes to KE
500
What is the formula for power?
Power= work/time
500
If there was a school bus, with kids on it, and the bus hits a stopped prius, why would the kids move forward into the seats?
Because an object in motion stays in motion until hit by an outside force, in this case the back of the seats.

What does the Phase Changes of Water graph look like?
a staircase with plateaus at 0 degress C and 100 degrees C

What is the units for force?
