Forces! (Newtons Laws/ Work and Energy)
First Law
objects will remain in their state of motion unless a force acts to change the motion (aka law of inertia)
Examples
Third Law
every action has an equal/opposite reaction
Examples
Second Law
velocity of objects changes when they're subjected to an external force
Examples
Formulas
difference form = change in momentum/change in time
force when the object has constant mass = mass x acceleration
Work
Formulas
W = F̅Δs cos θ
W = F*d
Can shift energy
Work is when a force that is applied to an object displaces it.

only the component of force parallel to the displacement = work
Unit = Joules
Energy
Different types
Potential
Potential Energy = mass x gravitational force x height
