Key Topics to Revise

1

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
2

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
3

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
4

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
