Newtons 1st Law - Inertia

Newtons 2nd Law - A = F / M

Newtons 3rd Law - Action and Reaction

An object at rest stays at rest

An object in motion stays in motion

Unless acted upon by an unbalanced force

When an object exerts a force on a second object

The second object exerts an equal and opposite force to the 1st object

Acceleration is change in motion

Acceleration is resisted by mass

Free Body Diagrams

Diagrams that show how an object is moving

Kinematic Equations

vi = initial velocity

Acceleration

Acc = v/t

V = x/t

x = position

vf = final velocity

vf = vi + at

Horizontally, vi = vf

Downward Acceleration

-9.81

Projectiles

If an object is moving then it is an projectile

Angled Trajectories

Time up = vf = vi = at

Time down = d = t(vf = vi) /2
