vocabulary
energy
The ability to do work or cause change.
kinetic enegy
Energy of motion
definion
Energy can change from one form to another. This is called energy transformation.
definion
Energy can move from one object to another.
Gravitational Potential Energy
Energy an object has due to its position
- Depends on the object's mass, height, and
the strength of gravity
gravity
The attractive force between objects; the force that moves objects downhill.
Potential Energy
Stored energy due to position or condition
examples
- A light bulb transforms electrical energy into light and heat energy
- A car transforms chemical energy (fuel) into kinetic energy (motion)
- A solar panel transforms light energy into electrical energy
examples
Examples:
- Heat transferring from a hot cup of cocoa to your hands
- A baseball bat transfers kinetic energy to a ball when hit
- The sun transfers light and heat energy to Earth
Energy Conservation
The law of conservation of energy states that energy cannot be created or destroyed, only transformed or transferred.
power
The rate at which one form of energy is transformed into another.
exampoles of kenetic energy
- Examples: running water, wind,
a moving car
what is the diffrence between tranfermation and transfer
Transformation alters the core nature or structure of something, while transfer simply moves it from one place to another without changing it. [1, 2]
3 Types of Heat Transfer:
Conduction: Direct Contact
Convection: Currents of Liquid & Gases
Radiation: Light Waves or Rays
examples of gravitation potential energy
Examples:
- A rock at the top of a hill
- Water behind a dam
- A book on a high shelf
Law of Conservation of Energy
The rule that energy cannot be created or destroyed.
examples of poteniol energy
a) Gravitational potential energy
b) Elastic potential energy
c) Chemical potential energy
does transfer of transition happen more often
transfer
true or false
heat always transfersfrom substancewith morethermal enegy to substance with less thermal energy until both reach the same tenmerature
true
examples of conservation
Example:
In a roller coaster, energy constantly changes between kinetic and potential energy, but the total amount of energy remains the same (ignoring small losses due to friction).
joule
Unit of work. 1 joule equals the amount of work done when you exert a force of 1 Newton to move an object a distance of 1 meter.
other forms of enegy
- Thermal (heat) energy
- Electrical energy
- Light energy
- Sound energy
- Nuclear energy
Does a caterpillar truly transform during metamorphosis if it still retains its memories as a butterfly?
Yes. Science shows butterflies actually retain memories from their caterpillar stage.
true or false there are 3 types of enegy
false
what are the two main category's of enegy
Kinetic (motion) and Potential (stored)
