100
The use of force to move an object
What is work
100
All energy can be divided into two main forms, ________ energy and ___________ energy
kinetic and potential
100
Heat energy
Thermal energy
100
Explain the transformation that takes place when you rub your hands together
Kinetic (movement of the hands) to thermal (heat produced from friction)
100
At what point on a roller coaster does the roller coaster have the most potential energy?
At the highest point
200
What is the equation for work
force x distance
200
The energy that an object has because of its position or condition
Potential energy
200
Energy caused by the movement of electrons
Electrical energy
200
Explain the transformation that takes place when you turn on a flashlight.
What is Chemical (of the battery) to electrical (flow of electrons) to light energy (from the light) and thermal energy (the heat produced by the light)
200
If you push on a door that says pull is work being done of the door? Why or why not?
No because work is the use of force to move an object. You exerted a force but did not move the object.
300
What is the ability to do work?
energy
300
The energy an object has because of its motion
kinetic energy
300
Energy available for release from chemical reactions
Chemical energy
300
A coal grill converts _____ energy to _____ energy
Chemical to thermal
300

How do you calculate work? 

work= force x distance

400
rate at which work is done

power

400
What two variables influence an objects kinetic energy and how?
Mass and speed More mass = more kinetic energy More speed = more kinetic energy
400

What is the equation for kinetic energy? 

KE= 1/2 (mass)(Speed)^2

400
Through the process of photosynthesis, ________________ energy from the sun is changed to stored ________________ energy.
solar (energy from the sun) to chemical (food plants make through photosynthesis)
400

Which of the following are types of both kinetic and potential energy? (there are 3) Mechanical, thermal, electromagnetic radiation, electrical, chemical, nuclear

mechanical, thermal, electrical

500
State the law of conservation of energy
Energy can neither be created nor destroyed. Instead, all forms of energy can be converted or transformed into other forms.
500

What is mechanical energy? 

Mechanical energy is combined potential and kinetic energy

500

A form of energy that is created by vibrating partibles that create waves that can travel through space This type of energy includes visible light, as well as radio waves, microwaves, and X rays

Electromagnetic energy

500
In a car, the ________________ energy in gasoline is burned to create heat energy, which is converted to ________________ energy to make the car go.
chemical, kinetic would also take potential, kinetic
500

What is energy transformation and energy transfer? 

transformation- convert from one form to another

transfer- energy passes from one object to another
