• a 50 kg football player charging at you

In this case, equilibrium means

• The rate of formation of products equals the rate of formation of reactant. 

• Balanced Forces

• Constant Velocity

• Forces going the same direction

Organize the following with their law

Groups:

(a) Newtons 1st law

,

(b) Newtons 2nd law

,

(c) Newtons 3rd Law

• Force equals mass times acceleration (F=ma)

• An object at rest will remain at rest unless acted upon by a force

• Inertia

• When a swimmer pushes the water backwards, the water pushes the swimmer forward

• In a collision, the forces two objects exert on each other are equal and opposite

• Objects resist changes to their state of motion

• For every action, there is an equal and opposite reaction

• Acceleration is produced when a force acts on a mass

• An object in motion will remain in motion, unless acted on by a force
