7.1 Circular Motion and Gravition Flashcards
1
Q
in what direction is Centripetal Acceleration?
A
toward the center of the circle
2
Q
Centripetal acceleration must involve a change in what?
A
The Velocity of the Object
3
Q
what is the speed of an object in circular motion called?
A
Tangential speed
4
Q
what is the correct equation for centripetal acceleration?
A
Ac= Vt2/R
5
Q
what term describes a force that causes an object to move in a circular path?
A
centripetal force
6
Q
a centripetal force acts
A
perpendicular to tangential speed but in the same plane.
7
Q
centripetal force can be calculated from centripetal acceleration by
A
multiplying by the mass
8
Q
A ball whirled in a circular motion will move off in a straight line if the string breaks. what is this due to?
A
its due to inertia
