The two basic types of energy.
What are Kinetic and Potential energy? (pg 10)
The type of energy that moves something.
What is kinetic energy?
A change in one form of energy to another form of energy.
What is an energy transformation?
The amount of energy transferred, divided by time is this.
What is power? (pg 9)
The transfer of energy.
What is work?
Energy can neither be destroyed or what?
What is created?
Energy is the ability to do work or to cause this.
What is change?
The energy an object has due to its motion is called this.
What is kinetic energy?
The gravitational potential energy of an object is equal to its weight multiplied by this.
What is its height? (pg 12)
The energy that you get when you pull back a rubber band.
What is elastic potential energy? (pg 13)
Kinetic Energy + Potential Energy =
What is mechanical energy?
A form of energy NOT associated with the particles of objects is this.
What is mechanical energy?
The formula to find the amount of kinetic energy.
What is 1/2 mass x speed2? (pg 11)
Velocity is another term for speed.
The energy you get from eating a peanut butter and jelly sandwich.
What is chemical energy?
The type of energy the ball has at point 3.
What is gravitational potential energy?
Type of energy that lightning is a form of.
What is electrical?
The type of reactions that occur in the sun.
What is nuclear fusion?
A 10 kg wagon is being pulled at a speed of 1 meter per second. This is the amount of kinetic energy the wagon has. (don't forget the unit)
What is 5 joules? (pg 11)
Whenever a moving object experiences friction, some of its kinetic energy is turned into this.
What is thermal energy?
Energy and work are measured in this unit.
What are joules?
The form that electromagnetic energy travels through space.
What is in waves?
The law of the conservation of energy.
What is when one form of energy is transformed to another, no energy is created or destroyed in the process?
A hat that weighs 5 newtons is hanging from a hook 2 meters above the floor. This is the amount of gravitational potential energy the hat has. (don't forget the unit)
What is 10 joules?
Fusion reactions in the sun cause nuclear energy to turn into this.
What is electromagnetic energy?
