Name that Energy
Stored energy is called this.
What is potential energy?
A girl runs into the person in front of her, causing that person to fall down.
What is energy transfer?
(KE -> KE)
This is what it's called when magnets want to separate from one another.
What is repel?
Describe how electricity is generated.
Magnets spin around copper a coil.
To generate electricity, kinetic energy is transferred to this device from moving water.
What is a water wheel or water turbine?
This type of energy can light an LED.
What is electrical energy?
A Diet Pepsi can on a string is bumped into another Diet Pepsi can, which results in the second can falling over.
What is energy transfer?
(KE -> KE)
This is what happens as the distance between 2 magnets increases.
What is... the magnetic forces decrease.
What factors affect how much electricity is generated?
The speed of the spinning magnets and the distance between the magnets and coil.
What type of energy is being harvested when rain is collected in an elevated rain barrel?
What is potential energy?
This type of energy is known as heat.
What is thermal energy?
Magnets spin around a copper coil, causing an LED to light up.
What is energy transformation?
(KE -> EE)
You try to stack 2 circular magnets together, but they're repelling each other. You flip one over. What happens?
What is... they attract
Kinetic energy is affected by 2 things. Name one.
What is speed or mass?
This black substance is mined and then burned, which transforms its chemical energy into thermal energy.
What is coal?
This is a specific type of stored energy that depends on the elevation of an object.
What is gravitational potential energy?
An elevated barrel of water is full. Water begins spilling out.
What is energy transformation?
(PE -> KE)
You're studying a model of a magnet and notice a force arrow on it. Does the arrow represent the force that the magnet is exerting OR the force that is acting upon it?
What is... the force that is acting upon it.
What happens to the potential energy of a ball as it is raised higher and higher into the air?
What is... it increases.
To generate electricity, kinetic energy is transferred to this device from moving air.
What is a windmill or a wind turbine?
This is energy of motion.
What is kinetic energy?
Water rushes down a pipe, causing a turbine to spin.
What is energy transfer?
(KE -> KE)
Magnetic fields and gravitational fields both exert this type of force.
What is a non-contact force?
How is energy transferred from one object to another?
Once energy is harvested and stored, what type of device is useful in controlling the flow of energy?
What is a gear?
