physics Flashcards
1
Q
what are the equations for the initial vertical and horizontal velocity
A
Vv=Ucos Vh=Usin
2
Q
When does circular motion occur
A
When the velocity is perpendicular to the force. also when the speed remains constant but the velocity changes.
3
Q
How do u derive velocity for circular motion
A
V=S/d=C/P (c=2Pir) P=1/T
=2pir/T
4
Q
what units is angular velocity in
A
Degrees or radians per second.
