Kinetic Energy
Kinetic Energy is more dependent on this quantity.
Velocity
At what location in the classroom would an object have the lowest amount of gravitational potential energy?
On the floor
This type of potential energy is stored in a spring that has been stretched out.
What is elastic potential energy?
This quantity is the rate at which work is done.
What is Power?
Will the magnetic potential energy increase or decrease as two south poles are moved closer together?
Magnetic potential energy will increase
How much more kinetic energy does a car travelling at 50 mph have compared to a car travelling at 25 mph?
4x as much
Would a person on a roller coaster have more gravitational potential energy at the top of a hill or at the bottom of a hill?
Top of the hill
This type of energy is stored in the bonds that form between atoms and molecules.
What is chemical potential energy?
This unit of power was developed as a comparison for steam engines by James Watt.
What is horsepower?
How much more kinetic energy does a car travelling at 60 mph have compared to a car travelling at 15 mph?
16x as much kinetic energy
How much more kinetic energy does a car travelling at 80 mph have compared to a car travelling at 20 mph have?
16 times as much
If a bowling ball and a car are sitting at the top of the same hill, which has a greater amount of gravitational potential energy?
The car
This type of potential energy is stored in the bonds and forces that hold the nucleus of an atom together.
What is nuclear potential energy?
You push a box with a force of 500 N for a distance of 10 meters. How much work did you do?
5000 J
This force does work by slowing down objects, eventually causing them to stop.
What is friction?
What is the kinetic energy of a 6 kg bowling ball moving at 5 m/s?
75 Joules
What is the gravitational potential energy of a 5 kg bowling ball sitting at the top of a 10 meter tall hill?
500 J
This type of energy can be released either slowly through the process of digestion, or quickly through burning.
What is chemical potential energy?
If an engine is 3x more powerful than another, how much more work could it do in the same amount of time?
3x more work
This is the process of taking smaller atoms and putting them together, releasing nuclear potential energy.
What is nuclear fusion?
What is the kinetic energy of a 1200 kg car travelling at 10 m/s?
60,000 Joules
What is the gravitational potential energy of a 1200 kg car sitting at the top of a 10 meter tall hill?
120,000 J
This is the process of taking a large atom and splitting it into smaller parts, releasing nuclear potential energy.
What is fission?
When you step on the gas in your car, you apply an average force of 500 N over the 1000 meter trip from your house to school. Over the round trip (to school and back), how much work does your car do?
0 J
The purpose of this area is to distribute and disperse energy during a car wreck before it reaches the driver.
What is the crumple zone?
