  1. radial
  2. centrifugal effect is a center fleeing tendency of an object to fly away from center, centripetal is the opposite. It is a center seeking force. example of centrifugal effect is in a car when tangential inertia and a centripetal force are acting upon an object it creates the centrifugal effect in which if you turn left the passenger will scoot towards the door. An example of centripetal force is when you spin a can on a string that enforces it to stay in circular motion.
  3. the type of velocity found by dividing theta by seconds
  4. omega=theta/t
  5. 360
  6. because 6.28 radians = 360 degrees = number of degrees in a circle.

  76. I used the tangent equation and derived for theta. I used the theta that I found and plugged it into the sin equation to find the opposite side, then I used the theory of similar triangles and lasers to find the radius.
