Studied by 0 peopleuniform circular motion
objects moving in a circle at constant speed and constant radius
r
radius (m)
T
period (s) - time for 1 revolution
v
speed (m/s)
frequency (f)
# of revolutions per second
direction of instantanius velocity
always tangent to the circle
is an object in VSM accelerating?
Yes, the direction of velocity is changing
direction of instantanious acceleration
always points inwards
centripetal acceleration
inward pointing acceleration
centripetal force
the name for the force pointed inwards that makes an object go in a circle
object is at top of a circle
gravitational force and normal force is pointed inwards/down
object is at the bottomn of a circle
normal force is pointed inwards/up and gravitational force is pointed outwards/downwards
Newtons Law of Universal Gravitation
Any two objects exert gravitational forces on each other. Fg=mg is only true near the surface of the Earth and assumes the force is constant
