Kinetic Energy
This type of energy is the energy of motion.
Kinetic Energy
This type of energy is stored energy based on an object's position.
Potential Energy
When energy changes from one form to another is is called an...
Energy Transformation
This is the amount of matter in an object.
Mass
Which has more gravitational PE: a basketball on a 10-foot shelf OR a basketball on a 3-foot shelf? Why?
Basketball on the 10-foot shelf because it is higher.
These two factors affect how much kinetic energy an object has.
Mass and Speed
These are the two types of potential energy we studied.
Gravitational and Elastic
When a ball is thrown upward, kinetic energy transforms into this type of energy for a split second then comes back down.
Gravitational Potential Energy
This is the unit we use to measure mass.
Kilograms / Grams
Which has more KE: a skateboarder going 10 mph OR a car going 10 mph?
The car (same speed but more mass)
True or False: An object sitting still on a table has kinetic energy.
False
A stretched rubber band has this type of potential energy.
Elastic Potential Energy
This law states that energy cannot be created or destroyed, only transformed.
The Law of Conservation of Energy
Weight is a measure of this force pulling on an object's mass.
Gravity
Which has more gravitational PE: a bowling ball on a 5-foot shelf OR a tennis ball on a 5-foot shelf?
The bowling ball (same height but more mass)
If a car doubles its speed, its kinetic energy does this.
KE increases dramatically.
A book sitting on a high shelf has more of this than a book on a low shelf. Be specific.
Gravitational potential energy
When on a swing, swinging up, what happens to the kinetic energy as it reaches the top.
The kinetic energy decreases (the object slows down)
What happens to your mass if you go from Earth to the Moon.
Nothing. Mass stays the same.
Which has more KE: a bicycle going 20 mph OR a motorcycle going 20 mph?
The motorcycle (same speed but more mass)
Between two objects moving at the same speed, this one will have more kinetic energy.
The Object with more mass
These two factors affect how much gravitational potential energy an object has.
Mass and Height
As a roller coaster goes down a hill, potential energy transforms into kinetic energy. Explain why this transformation happens.
The coaster loses height as it starts to move.
What happens to your weight if you go from Earth to the Moon.
Your weight would decrease. (Lighter)
Which has more elastic PE: a spring compressed 2 inches OR a spring compressed 6 inches?
The spring compressed 6 inches (more compression = more elastic PE)
