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

200

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)

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
