physics bro

what is a system

An object or group of objects chosen for study

what is an energy store

A way that energy can be stored within a system such as in batteries and springs

what is an energy transfer

Movement of energy from one store to another

what is the conversation of energy

Energy cannot be created or destroyed, only transferred between stores

name the several ways energy can be stored

kinetic energy store

gravitational potential energy store

elastic potential energy store

chemical energy store

thermal energy store

electric energy store

give 2 examples of changes in energy stores

Object projected upwards

Moving object hitting an obstacle

state 4 energy transfer parhways

• Mechanical work

• Electrical work

• Heating

• Radiation

define equilibrum

A state where all forces acting on a system are balanced(1)

So there is no net change in motion or energy(1)
