Form of energy stored in molecules
Chemical energy
100
Which points have some potential energy and some kinetic energy
Point B and D
100
Please explain what form of energy is being converted from the scenario below
Mechanical energy to electrical energy
100
The definition of gravity?
The force of attraction between two objects or the acceleration or pull of an object towards earth
100
What is a force?
A push or pull or the ability to change the motion of an object
200
Energy that comes from electrical charge
electrical energy

Explain the transfer of energy in this picture
The ball is releasing from the hands and gain potential energy. Once the ball reach the highest point it is all potential energy. When the ball falls down it converts to kinetic energy.
200
Please explain what form of energy is being converted from the scenario below
Radiant energy to electrical energy
200
What are two variables that affects the force of gravity?
mass and distance
200
How can you affect the potential energy an object has?
Changing the height or the position of the object
300
form of energy stored in the nuclei of an atom
Nuclear energy
300
This dam harness the energy from the water and convert it to electrical energy. At which point is the highest amount of kinetic energy?
Point 4.
300
Please explain what form of energy is being converted from the scenario below:
A Battery to a flashlight
Chemical energy or potential energy to radiant energy
300
What can affect the acceleration of gravity, or the pull of an object to the earth?
Air resistance
300
How change you change the amount of kinetic energy an object has?
If you change the speed of an object you can change the kinetic energy. You can speed it up or slow it down.
400
Energy carried by electromagnetic waves
Radiant energy
400
This dam harness the energy from the water and convert it to electrical energy. At which point is the highest amount of potential energy?
Point 1
400
Please explain what form of energy is being converted from the scenario below:
Sunlight to the leaf of a carrot to your stomach
Radiant to Chemical to potential energy
400
What is the difference between weight and mass? (daily double)
Mass is the amount of matter you are made of, weight depends on the gravitational pull of an object towards the earth.
400
The SI unit for energy
Joules
500
What are two forms of mechanical energy
Potential and kinetic energy
500
Explain how the energy is being transferred in this object. (daily Double)
The flowing water at the top has potential energy, as it flows through the wheel it is converted to kinetic energy. When it turns the wheel it is also turning the gears inside the structure using kinetic energy to break down the grains into flour
500
Please explain what form of energy is being converted from the scenario below:
Electrical to Mechanical (kinetic energy)
500
The two objects in the picture is the girl and the ground. Please explain what happens to the gravitational force between the two objects in points 1 and 2.
In 1, the girl is climbing higher away from the ground. So the distance between the her and the ground is farther and the gravitational force is weaker. In point 2, the girl is sliding down and coming closer to the ground, so the gravitational force between the two is stronger
