CIRCULAR MOTION AND GRAVITATION
COLLEGE PREPARATORY PHYSICS

TEXTBOOK: Chapter 7, pages 257 - 268.

OBJECTIVES:

Relate Newton's second law to circular motion.
Describe the resulting motion of an object if the centripetal force acting on it increases.
Give examples of centripetal force.
Use the mathematical definition of centripetal force and acceleration in problem solving.
Analyze the relationship between centripetal force, velocity, and radius for an object moving in a circular path.
State Newton's Law of Universal Gravitation both in words and as a mathematical formula.
Use the mathematical formula for Newton's Law of Universal Gravitation to predict how the gravitational force varies as the masses or the distance between the object changes.
State the value of the Universal Gravitation constant.
Solve problems using the Law of Universal Gravitation.
Recognize that the motion of artificial satellites is circular motion about the earth.
Solve problems that relate the orbital velocity of a satellite to its distance from the earth.
Determine how the orbital velocity and launch angle determines the shape of the orbit of a satellite.
