1. Uniform Circular Motion

3. Motion along a circular path at a
constant speed.

8. Centripetal Force

9. • Any force or sum of forces which cause an
object to move in a uniform circular motion.

11. • The earth’s
gravity acts like
a string keeping
the satellite in Satellite
orbit around the
earth.
Gravity
• Fc=Fg
Earth

12. If it comes off the track, the train
would continue in a straight line
tangent to the circle.
Fc=FN+Ff

13. If the driver loses grip, he
will slide in a straight line
on a tangential path to the
circle.

14. The people “stick” to the
wall because their
centripetal force is
directed tangent to the
circle.
