Answer 1

Answer:

hi

Explanation:

Term (symbol) Meaning

Uniform circular motion Motion in a circle at a constant speed

Radian Ratio of an arc’s length to its radius. There are 2\pi2π2, pi radians in a 360 \degree360°360, degree circle or one revolution. Unitless.

Angular velocity (\omegaωomega) Measure of how an angle changes over time. The rotational analogue of linear velocity. Vector quantity with counterclockwise defined as the positive direction. SI units of \dfrac{\text{radians}}{\text {s}}

s

Centripetal acceleration (a_ca

c

a, start subscript, c, end subscript) Acceleration pointed towards the center of a curved path and perpendicular to the object’s velocity. Causes an object to change its direction and not its speed along a circular pathway. Also called radial acceleration. SI units are \dfrac{\text m}{\text s^2}

s

Period (TTT) Time needed for one revolution. Inversely proportional to frequency. SI units of \text{s}sstart text, s, end text.

Frequency (fff) Number of revolutions per second for a rotating object. SI units of \dfrac{1}{\text{s}}
