Topics in Gravitation
1
Uniform Circular Motion
- Uniform circular motion is motion with constant speed along a circular path
- Velocity changes continuously due to change in direction, even though speed remains constant
- Centripetal force is required to maintain circular motion, always directed toward the center
2
Universal Law of Gravitation
- Every object in the universe attracts every other object with a gravitational force
- Force is directly proportional to product of masses and inversely proportional to square of distance
- Newton derived this law by comparing moon's motion with apple's fall
3
Free Fall and Acceleration due to Gravity
- Free fall occurs when only gravitational force acts on an object
- All objects fall with same acceleration in absence of air resistance
- Acceleration due to gravity g = 9.8 m/s² (approximately 10 m/s²)
4
Weight and Weightlessness
- Weight is the force of gravitational attraction on an object by Earth
- Weight = mg, measured in Newtons (N)
- Weight varies with location due to changes in g
