The capacity to do work or the ability to cause change.
What is energy?
Energy made of light rays that travel in waves, such as sunshine from the sun.
What is radiant energy?
The energy of heat produced through contact or by jiggling particles
What is thermal energy?
To change energy from one form into another form.
What is convert (or transform)?
Energy sources that won't run out.
What is Renewable?
When something becomes different—like a light bulb turning on or a car rolling—it is evidence that energy is present.
What is change?
A form of energy that comes directly from a vibrating object, like a guitar or saxophone.
What is sound energy?
An ability to do work that comes from the movement of electrical charges.
What is electrical energy (or electricity)?
The movement of energy from one object or place to another object or place.
What is energy transfer?
To change from one form to another.
What is convert/transform?
Stored energy that has the ability to cause change at a later time, such as a roller coaster sitting at its highest point
What is potential energy?
The energy an object has due to both its motion and its position.
What is mechanical energy?
DOUBLE JEOPARDY!!!
Force that opposes motion and creates heat when two objects rub together, such as a spacecraft re-entering Earth's atmosphere.
What is friction?
An energy resource that can be easily replaced after it is used or can never be used up, such as sunlight
What is renewable?
Light rays that travel in waves.
What is radiant Energy?
The form of energy that an object has when it is in motion, like a student running or kicking a soccer ball.
What is kinetic energy?
DOUBLE JEOPARDY!!!
When light bounces off a surface, like grass reflecting light back into the sky, it is called light that is:
What is reflected?
Electricity that flows through wires in currents to power appliances like lamps or toasters.
What is current electricity?
Natural resources, like coal, that cannot be easily replaced because they take millions of years to form.
What is nonrenewable?
Energy an object has from its motion and position.
What is Mechanical Energy?
A force acting on an object that causes the object to move in the direction of the force
What is work?
Sound energy moves these tiny invisible bits of matter in the air so that our ears can hear noise.
What are air particles?
Lightning and socks sticking together in the dryer are both examples of this type of electricity
What is static electricity?
The prevention of wasteful uses of resources and saving energy.
What is conservation?
Energy sources that take millions of years to replace.
What is Nonrenewable?
