Roller Coasters
How do roller coaster cars move if they don't have an engine?
Momentum and a chain with a motor
What kind of energy did the bumper coaster use?
Kinetic energy
Where was the energy stored in the twist-o-matic?
The rubber bands
What is kinetic energy?
energy an object has due to its motion
What pulls the roller coaster down when it gets to the top of the hill?
Gravity and/or momentum
How did the height of the bumper coaster affect the speed of the marble?
The higher the track the faster the marble will roll
Would a thick rubber band of thin rubber band make it go faster?
Thin
What is potential energy?
energy that is stored in an object/person/thing
What two types of energy do roller coasters use?
Potential and Kinetic energy
How did the distance of the bumper marble affect the roller coaster?
The closer the bumper marble, the faster the rollercoaster cart marble will stop
What is two things that could effect the speed of the twist-o-matic besides the rubber bands?
Size and weight of the twist-o-matic
What is it called when energy is passed on from one object to another?
Conduction
At what point on a roller coaster does it use potential energy?
At the top of a hill
what would have happened if we dropped our roller coaster marble from a higher point?
The marble would have gone further and faster
What kind of energy was used on the twist-o-matic ride?
Potential energy
How do humans/animals get energy?
Food, water, sleep
At what point does a roller coaster use kinetic energy?
When going up or down a hill
what would have happened if the marble was smaller or larger?
It would stop the bumper coaster faster/ slower
How are the pom pom sling shot and the twist-o-matic activity similar?
Both use different distances to see the effect it has on the objects
Gasoline and coal
