Key Topics to Revise
Forces and Types of Forces
- Force is a push or pull that can change the state, size, or shape of a body
- Forces are classified into Contact Forces and Non-contact Forces
- Contact forces require physical contact: friction, normal reaction, tension, spring force, collision force
Moment of Force and Equilibrium
- Moment of force (torque) is the turning effect of force about an axis
- Moment depends on magnitude of force and perpendicular distance from axis
- Clockwise moments are negative, anticlockwise moments are positive
Centre of Gravity
- Centre of gravity is the point where entire weight of body appears to act
- Position depends on shape and mass distribution of the object
- For regular shapes, CG lies at geometric center
Uniform Circular Motion
- Uniform circular motion has constant speed but changing velocity direction
- Centripetal acceleration always points toward center of circle
- Centripetal force is always required for circular motion
