Circular motion/oscillations

Circular motion/oscillations

1. Newtons laws

   • First law
     • Every body continues in its state of rest, or of uniform motion in a straight line, unless compelled to change that state bey a net force
   • second law
     • For a body of constant mass, its acceleration is directly proportional to the net force applied to it
   • Third law
     • Whenever one body exerts a force on another, the second exerts an equal and opposite force To every action there is a equal and opposite reaction

2. newton

   • the force that will cause 1 kilogram to accelerate at one meter per second in its direction

3. Centripetal

   • acceleration
     • change in angles / change in time
   • force
     • mv^2 / r
   • velocity
     • radius * angular speed
   • units
     • 1rad = 57.29 degrees

4. oscillations

   • period
   • frequency
   • amplitude
   • Simple harmonic motion
     • a= -angular velocity^2 * distance from fixed point
     • angular frequency
       • Angular frequency=  2pie * frequency
     • Kinetic energy
     • potential energy
     • x - diplacement
       • cos
         • x= Xo Cos Angular velocity * time
         • velocity
           • V= -Xo Angular velocity * Sin * Angular Velocity * time
       • sin
         • x= Xo Sin Angular velocity * time
         • velocity
           • v= Xo Angular velocity Cos Anguar velocity * time
     • Velocity
