Tention goes in what direction?

inwards or towards the center

Velocity is what to a circle?

tangential or tangent

Force and velocity are what to each other?

perpendicular

What is the distance around circles?

Are objects who are in uniform motion acclerating?

Yes, since direction is always chaging so velocity is changing

an ________ force is needed to make an object move in a cicular path

centripetal

in uniform cicular motion, the direction of the contripetal force is always __________ to that of the instantaneous velocity

perpendicular

the freqency unit of hertz is equalent to _____

cycle

f = rev/s

T = s/rev

cm/100 = m

g / 1000 = kg
