Energy
The ability to do work.
Define a cause?
Why something happens
An objects location is called what?

What is energy transfer?
Movement of energy from one place to another.
What does and HVAC technician do?
Installs and repairs heating ventilation and air conditioners.
What are the 2 types of energy?
Potential Energy
Kinetic Energy
What is an effect?
What is applied force?
The force to apply to an object to get it to move.
Kinetic energy from a baseball bat hitting a ball transfer into what kind of energy?
Sound energy.
Using a car as an example, how do speed, energy and motion work together?
The shape of a car is curved on the front. The curve allows air to pass over with less energy lost. A faster speed means the car uses less fuel.
Energy that is stored is called?
Potential Energy
The domino has potential energy, because it is standing upright.
What is the effect in the statement above?
The domino has potential energy.
A book is pushed across the table, what has to be true for this to happen?
The applied force must be greater than the force of friction.
John kicks a soccer ball. What is it called when Johns foot hits to the ball?
Explain how energy is transferred.
Collision
The kick transfers kinetic energy to the ball.
How does knowing about energy and motion help obey God's command of taking care of the earth?
Collisions help you play sports
Knowing about light energy can help you take care of the earth
Energy due to an objects motion is called?
Kinetic Energy
The domino changes to kinetic energy as a result of being pushed.
What is the effect in the statement above.
A car and a semi truck are traveling at the same speed. Which has more kinetic energy?
The bus
Patty flips the switch on the wall before entering her bedroom. What kind of energy is created?
Light energy
What is a tool used to show how collisions work?
Newton's Cradle
Where does energy come from?
A wagon rolls down a hill. As the wagon rolls down the hill, what happens?
Potential energy changes to kinetic energy as the wagon rolls down the hill.
How does and objects speed affect it's kinetic energy?
The faster an objects motion, the greater kinetic energy.
Sally hits a cue ball with a pool stick. The cue ball transfers kinetic energy to the other pool balls. What happens to the cue ball because of the collision?
It changes direction.
