Si unit for frequency
hertz (hz)
Force goes in what direction ?
inwards or towards the center
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?
circumference (2πr)
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
