Equations for uniformly accelerated linear motion
x = xo + vot + (1/2)at^2
v = vo + at
v^2 = vo^2 + 2ax
v(avg) = (1/2)(v + vo)
Distance vs Time graph (d/t)
-Slope is velocity
-Area under the curve is meaningless
Velocity vs Time graph (v/t)
-Slope is acceleration
-Area under curve is displacement
Displacement
x = v(avg) * t
Acceleration
a = (v - vo)/t
Peak height of a projectile
vo*sin(theta) = sqrt(2gh)
Factors that change air resistance
Speed, surface area, shape
Mass and Air Resistance
-Air resistance has less effect on a more massive object
-However, it does not CHANGE air resistance
Inertia
The tendency of an object to remain in its present state of motion (EX: massive object will accelerate more slowly)
Newton's Third Law forces NEVER act on the ______ _______.
same system
The normal force on an inclined plane is:
mgcos(theta)
The net force due to gravity and the normal force on an inclined plane is:
mgsin(theta)
Centripetal Force
(m*v^2)/(r)

always caused by another force (either gravity, electromagnetic, or contact forces)
T or F: Friction always opposes motion
F: Friction always opposes relative motion. The vector points in the direction that would prevent surfaces from sliding past each other
Force of Static Friction
fs <= us*Fn
Force of Kinetic Friction
fk = uk*Fn
Hooke's Law
F = -k*dx
