Newtonian Mechanics
Newton's Laws
1st Law
An object in rest or in motion remains so unless acted upon by a net external force.
2nd Law
The force of an object is mass times acceleration.
3rd Law
Every action has an equal and opposite reaction.
Misconceptions
Object will naturally stop without external forces
An unbalanced force will cause an object to move with constant velocity
Larger objects will apply larger forces to smaller objects
Kinematics
Ramps
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
Friction
f = μN
f = friction force
μ = coefficient of friction
n = normal force
Projectiles
Angled Projectiles
Horizontal
x = vix•t + 0.5
ax
t2
vfx = vix + ax•t
vfx2 = vix2 + 2*ax•x
Vertical
y = viy•t + 0.5
ay
t2
vfy = viy + ay•t
vfy2 = viy2 + 2*ay•y
x = vix•t + 0.5
ax
t2
vfx = vix + ax•t
vfx2 = vix2 + 2*ax•x
Equations aplicable to both
d = vi•t + 0.5
a
t2
vf = vi + a•t
vf2 = vi2 + 2*a•d
