a force acting upon an object to cause a displacement. (key words: force, displacement, and cause)
Work = force × distance
SI unit Work and Energy
(physics) the capacity of a physical system to do work
Examples of different energies
Potential, kinetic, heat, light, sound, electrical, magnetic, solar, nuclear
(mass) x (g) x (height)
Examples of potential energy
Coiled spring, water in a dam, stretched rubber band etc
a running dog
Examples of kinetic energy
Moving car, stone falling, wind, tide etc.
Potential energy stored in chemical bonds (atoms and molecules). It is released in a chemical reaction, often producing heat as a by product.
Example of chemical energy
Energy stored in food and fossil fuels
a clap of thunder
a power line
Example of magnetic energy
Cranes, door locks of cars
Energy we get from the sun
fusion or fission
Principle of conservation of energy
Energy cannot be created or destroyed, but may be converted from one form to another
Energy that does not run out.
Examples of renewable energy
Solar, wind, tidal, hydro-electric, geothermal, biomass
Non-renewable sources of energy
Fossil fuels such as coal, oil, gas, turf
Energy generated from crops, plant waste and wood
Energy generated from heat below the plant's surface
(physics) the rate of doing work
A measure of power equal to one joule of work per second.
(interactions between two objects)
SI unit used to measure energy
A parameter that is a measure of a spring's resistance to being compressed or stretched.
3.6 million Joules
The potential energy from an object's height
a mousetrap is an example of what type of energy?
