  • TYPES OF FORCES

  • MAGNETIC FORCE

  • MAGNETIC FORCEMagnetic force is the force of attraction or repulsion acting between magnetic materials such as iron.Magnetic objects have two poles : - north pole south poleDifferent poles attract each other.

    Identical poles repel each other.

  • What happens to the iron bar?

  • ELECTROSTATIC FORCE

  • ELECTROSTATIC FORCEAll objects contain electric chargers

    Electrostatic force is the attractive or repulsive force between charge carrying object at rest.

  • FRICTIONAL FORCE

  • FRICTIONAL FORCEFriction is the force that makes objects resist motion across or against another one.

    Friction is caused by two surfaces, which are in contact.

    Friction always acts in the opposite direction of the movement.

  • GRAVITATIONAL FORCEThe gravitational force of the Earth pulls all objects towards the center of the Earth.

    Gravitational force depends on the:Mass of objects,Distance between them
