  • Forces
    • Vector and Scalar Quantities
      • vector quantities have a magnitude and direction.
        • e.g. force, velocity, displacement
      • scalar quantites have magnitude and no direction
        • e.g. speed, distance, mass
    • Contact and Non-Contact Forces
      • a contact force is when two objects have to be touching for a force to act
        • e.g. friction, air resistance
      • a non contact force is when objects don't need to be touching for the force to act
        • e.g. magnetic force, gravitational force
