Physics Topic 1: Energy Stores and Systems.

Energy Stores and Systems:

Energy Stores:

Thermal

Kinetic

Gravitational potential

Elastic potential

Chemical

Magnetic

Electrostatic

Nuclear

Energy is transferred mechanically (force doing work), electrically (work done by moving charges), by heating or by radiation(light or sound)

System = Single object or a group of objects

When a system changes, energy is transferred.

Closed systems is when neither matter or energy can leave.

Examples:

The initial force exerted by a person to throw a ball upwards does work. It causes an energy transfer from the chemical energy store…
