Illustration used to show applied forces and reactions of a motion event.

9.8 m/s/s/ acceleration

An object in rest or in motion remains so unless acted upon by a net external force.

The force of an object is mass times acceleration.

Every action has an equal and opposite reaction.

Object will naturally stop without external forces

An unbalanced force will cause an object to move with constant velocity

x = vix•t + 0.5axt2

vfx = vix + ax•t

vfx2 = vix2 + 2*ax•x


Horizontal

Equations aplicable to both

d = vi•t + 0.5at2

vf = vi + a•t

vf2 = vi2 + 2*a•d

Larger objects will apply larger forces to smaller objects

Vertical

x = vix•t + 0.5axt2


vfx = vix + ax•t


vfx2 = vix2 + 2*ax•x


y = viy•t + 0.5ayt2


vfy = viy + ay•t


vfy2 = viy2 + 2*ay•y


f = μN

f = friction force

μ = coefficient of friction

n = normal force

the steeper the surface, the faster the object will fall

force of gravity and normal force acting upon object on incline plane

(force of gravity = weight) works in the downward direction

normal force is perpendicular to the surface
