100

The ability of a system to do work:required for changes o happen within a system.

Energy

100

energy that is stored

potential energy

100

scientist measure potential and kinetic energy in this unit of measurement

joules (J)

100

On an apple tree the apples with the most potential energy are located where?

at the top of the tree

200

a unit used to measure energy

Joule

200

energy of motion

kinetic energy

200

the statement: energy can only change forms and cannot be created or destroyed is also know as what law.

the law of conservation of energy

200
On a roller coaster the maximum kinetic energy is located where?

at the bottom of the hill

300

a group of interacting parts, interrelated, or interdependent elements forming a complex whole

system

300

This type of energy depends on gravity. The higher an object is the more of this type of energy there is

potential energy

300

If the total mechanical energy of a pendulum system is 100 J: 

Where does the pendulum have 100 J of kinetic energy? And at that point what would the measurement of Joules be for the potential energy?

At the bottom of its swing

zero joules for potential 

300

something measurable that can change 

physical variable

400

the change of energy from one form to another 

energy transformation

400

This type of energy depends on mass and velocity. The more mass the greater of this type of energy. 

kinetic energy

400

 If the total mechanical energy of a pendulum system is 100 J: 

Where does the pendulum have 100 J of potential energy? And what would the kinetic energy be at that point?

At the highest point on both sids (when it pauses)

The kinetic energy would be zero joules at these points 

400

As you swing and your body collides with  air particles the kenetic energy is transfered to the particles. this resistance is called what?

air resistance 

500

a form of energy produced by a machine or moving part

mechanical energy

500

These two types of energy added together gives you the mechanical energy that is measured in joules.

kenetic and potential

500

 If the total mechanical energy of a pendulum system is 100 J: 

Where does the pendulum have 50 J of potential energy and 50 J of kinetic energy? 

At the halfway point between the top (where it pauses) and the  bottom. 
500

another force that slows you down in addition to air resistance is what 

friction.
