Energy of Motion
What is Kinetic Energy
100
Explain the transformation that takes place when you rub your hands together. START FROM THE SUN ( 5 steps)
What is light energy( from the sun) to chemcial energy (plants make sugar) to chemical (stored in bonds in food) to kineitc (movement of the hands) to thermal (heat produced from friciton)
100
As the mass of an object moving at a given speed decreases its kinetic energy will ______________________.
What is decrease
100
Wind turbines convert _________________ energy into eletrical energy.
What is kinetic
100
An energy source that is replinished continually (give an example)
What is renewable resource - the sun
200
The type of Energy that depends on mass and position
What is potential energy
200
Explain the transformation that takes place when you turn on a flashlight. From the battery to the light. 4 steps
What is Chemical (of the battery) to electrical (flow of elctrons) to radient (of the light) to thermal ( the heat produced by the light)
200
As the speed of a falling object increases, its potential energy will _____________________.
What is decrease
200
sugary foods can generate high amounts of energy because of the initial _______________________ energy of the food.
What is chemical potential
200
An energy source that is used up faster that is can be replaced. (give an an example)
What is a nonrenewable resource - coal
300
Type of energy that depends on the temperature of molecules.
What is thermal or heat energy
300
Explain the transformation of a book falling from table. Explain the type of energy and where it comes from. 3 steps
What is Potential ( due to the position of the book) to kinetic ( motion of the book) to thermal ( the friciton between the book and the air)
300
When you drop a book on the floor, what happens to its original potential energy?
What is the potential energy was transfered to kinetic and thermal energy
300
Explain how a roller coaster works using both potential & Kinetic energy
The roller coaster will start with potential energy, as the roller coaster moves the kinetic energy will increase and the potential will decerase
300
A device that transforms kinetic energy into electrical energy.
What is a turbine (generator)
400
Type of energy that depends on the flow of electrons
What is electrical energy
400
When you turn on a light what types of energy are produced
Light, thermal
400
A basketball is dropped from a height of 2m and another identical basketball is dropped from a height of 4m. Which ball has more kinetic energy just before it hits the ground?
The basketball dropped from a height of 4m because it has more speed.
400
Explain hydroelectric energy and give one advantage and one disadvantage.
What is hydroelectric energy is using the potential energy of water and turning it into electrical energy. One advantage is it does not pollute. One disadvantage is that it disrupts aquatic life.
400
State the Law of Conservation of Energy
What is Energy can not be created of destroyed it can only be transfered or tranformed.
500
Type of energy stored in food
What is Chemical energy
500
Explain the transformation that takes place to make a toaster work using a wind turbine. wind. (5 steps)
What is kinetic energy (of the wind) to kineitc energy (the baldes to spining) to electrical ( the turbine turns a generator and makes a flow of electons) to thermal ( heat from the toster) to radient ( when the toaster get hot enough it will emmit light)
500
When you drop a tennis ball, it hits the floor and bounces back up. But, it does not reach the same height as before and each time bounce is smaller than the previous one. However, you notice the tennis ball is slightly warmer after it finishes bouncing. Explain how this happens
During each bounce, some of the kinetic energy of the ball in transferred into thermal energy. As a result, energy is not created or destroyed, but only changes form so that the law of conservation of energy is obeyed.

Where does all energy originate from
the sun
