This roller coaster goes 10 m/s and drops 60 m. The mass of the people on the ride is 3000 kg. This is the Kinetic energy of the roller coaster.
What is 150,000 joules?
100
When a spring cannot stretch back to it's original size NOR shape.
What is the Elastic Limit?
100
The number of the force pulling on an object in free fall. Such as in the egg drop project.
What is -9.8 m/s^2?
200
Work over time.
What is Power?

This force prevented you from getting soaked when you swung water around your head like a crazy person.
What is centripetal force?
400
m1v1 + m2v2 = m1v1 +m2v2
What is the formula for inelastic collisions?
400
This is the spring constant of a spring that is stretched from 0.2m to 0.6m when a 10 N force is applied.
What is 25 N/m ?
400
When the total energy in a system does not change, meaning potential and kinetic energy equal the total energy at all times.
What is conservation of energy?
400
These are what you were looking for in the stairs lab, where you got to run up the staircase in school (Finally!).
What are work and power?
500
The formula for spring force.
What is F = -kX ?
500
This is the velocity of two cars that coupled after a head on collision. Car one (1000 kg) was moving at 10 m/s and car two (1500 kg) was moving at -7 m/s.
What is -0.2 m/s ?
500
Two cars collide and their velocities combine, creating one system.
What is an inelastic collision?
500
You shot basketballs, a turkey, a balloon, a rock, a ping pong ball, and a plastic bag to learn about this.
