- 2. Multiple Choice
A tiny pig is dropped from the top of a building and lands safely on a trampoline. The tiny pig will have an increase in what type(s) of energy as it falls?
gravity
potential energy
kinetic energy
all of the these
- 3. Multiple Choice
On the right of the image is a graph of the energy of a skateboarder as he travels down a track. Using the diagram on the left, at which point on the track does the graph correspond to?
Point A
Point B
Point C
- 4. Multiple Choice
Katy wants to design a roller coaster where the passenger is traveling super fast at the bottom. What characteristics should the roller coaster have?
It should be flat and close to the ground. This way the passenger will have an increase in speed because he/she starts out close to the ground.
It should have no friction and the passenger should start off high above the ground. This way the passenger starts out with a lot of potential energy that can be transformed into kinetic energy.
It should have lots of friction and be very tall. This way the passenger will speed up because of the large amount of friction.
It doesn’t matter how you design the rollercoaster the passenger’s speed will be the same at all points on the rollercoaster.

- 8. Multiple Choice
What type of energy does your skater have at the top of the skate park?
thermal
kinetic
potential
- 9. Multiple Choice
Stored energy is...
kinetic energy
potential energy
thermal energy
- 10. Multiple Choice
Energy an object has due to motion
Kinetic Energy
Potential Energy
Thermal Energy
- 11. Multiple ChoiceDo you think the Skater will make it over the first hump?
(No friction on the track)No, because his potential energy will be converted to thermal energyNo, because he doesn’t have enough potential energyYes, because all of his potential energy will be converted to kinetic energyYes, because some of his energy will be potential and some kinetic - 12. Multiple Choice
Do you think the Skater will make it over the first hump if there where a lot of FRICTION on the track? (select all correct possibilities)
No, because his potential energy will be converted to thermal energy
No, because he doesn’t have enough potential energy
Yes, because all of his potential energy will be converted to kinetic energy
Yes, because some of his energy will be potential and some kinetic

Multiple ChoiceWhich would NOT change the potential energy of the skater?putting the skater higher up on the trackincreasing the frictionmaking the track steeper and further from the groundmoving the starting point of the skater
- 15. Multiple ChoiceWhat is the relationship between PE and KE?inversedirectunrelatedinverse and direct
- 16. Multiple ChoiceWhen you increase mass you ___________ the kinetic energy.decreaseincreasedo not change
- 17. Multiple ChoiceWhen the skater is high on the track the _________ is high but the _____ is lower.speed, frictionfriction, kinetic energykinetic energy, potential energypotential energy, kinetic energy
- 18. Multiple ChoiceWhen friction is high the motion of the skater is:increaseddecreasednot affected
- 19. Multiple ChoiceWhich statement is true about a skater on a U shaped track?speed remains constant from one end to the otherspeed starts high at the top and reduces as the skater reaches the bottom of the trackspeed increases as they move down the track and then decreases as they move up the other sidespeed is zero the entire time
