ENERGY
What is ENERGY?
The ability to do work, to make things happen, and to cause change.
What is Gravitational energy?
Energy started in an object due to its position above the Earth.
What is wind energy?
Energy from moving air is converted by wind turbines.
What is water energy?
Energy from flowing water. Also called hydro energy.
What is kinetic energy?
Kinetic energy is the energy of motion, observable as the movement of an object or subatomic particle.
Is energy helpful to humans?
YES
What are examples of Gravitational?
Weight.A car that is going downhill.A yoyo after it is released and more.
Is wind energy good for the environment?
YES.
Is water energy good for the environment?
YES.
What can we use kinetic energy for?
Flying an airplane, walking and running, Cycling ect.
What are examples of Energy?
Examples of energy are: light energy, heat energy, mechanical energy, gravitational energy, electrical energy, sound energy, chemical energy, nuclear or atomic energy and so on. Each form can be converted or changed into the other forms.
What would happen if there was no gravity?
If there were no gravity, the Earth would not remain intact, and everybody would be flying
Why do we need wind energy?
It provides electricity without burning any fuel or polluting the air.
What are examples of water energy?
A hydroelectric dam, Wave power, Tidal power
What are examples of kinetic energy?
A person walking, a soaring baseball, a crumb falling from a table and a charged particle in an electric field are all examples of kinetic energy.
When you turn on an iron, _______ energy is transferred to ______ energy.
Electrical and thermal.
How is gravity helpful to humans?
Due to gravity we can hit the ground without losing contact with it.
Are wind turbines good for the environment and how?
Yes they are because they save electricity.
Why might dams be good for the environment?
Yes they are because they save the energy which is renewable energy.
When can we use kinetic energy?
After work has been done that is when we use it.
Are there different types of black holes?
Yes, stellar-mass, supermassive, and intermediate-mass.
Does gravity affect energy?
A stronger gravitational pull will also result in more gravitational potential energy.
How much does a wind turbine produce?
21.6 kWh.
How do dams make energy
A hydroelectric dam converts the potential energy stored in a water reservoir behind a dam to mechanical energy—mechanical energy is also known as kinetic energy.
Does an electron in an atom move at all?
Generally atoms' electrons do not move in anything like the classical sense.
