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
