Equational Manipulation
The force equation for circular motion solved for mass.
F/a → What is mass
This force keeps the moon in orbit.
What is Gravity
An object is traveling in uniform circular motion. At 12' oclock relative to a clock, where where would the velocity vector pointed toward.
What is, straight left. (Velocity vector is tangent and continues straight from position.
A 2 kg object moves in a circle at 4 m/s with radius 2 m. Find force.

What is 2.5 m/s²
Motion where both speed and direction change.
What is non-uniform
Equation used when period is expressed in terms of frequency.
What is Frequency Formula
The shape of a planet's orbit around the sun.
What is ellipse
What happens to velocity if radius is constant and speed increases?
What is increases
Time for one revolution if frequency is 2 Hz.
What is 0.5 seconds
This causes acceleration in non-uniform circular motion.
