What is energy

The capacity for doing work. This means work (energy) is done under a cause.

What forms does energy have

Potential, kinetic, chemical, thermal, nuclear, thermal and electrical

First law of

Thermodynamics - energy can neither be created nor destroyed, only change from one form to another

The measurement of energy is

Joules

Kinetic energy

The transferring of potential energy into movement

What property would energy be

Quantitative with actions associated with motion

What is work

The transfer of energy between objects or energy transformed

When applied to motion

Work done is a dependent on the force applied and the distance covered W = FxS

🔺= delta

Signifies a change in quantity

By lifting an object

You increase it’s gravitational potential

The SI unit for work

Is Joule for James joule

One joule of work is equal to

Lifting an apple one meter

Lighting a 100 watt lightbulb for 0.01 second

Hearing 0.2 mL of water by 1.0 degree Celsius
