1.10 identify different types of force such as gravitational or electrostatic

Different sorts of Force:

  • Gravitional force or weight: The pull of earth due to gravity.
  • Normal Reaction: Simple reaction that stops something when to apply force to it.
    E.g.: A book is kept on the table which has a normal reaction on it. Otherwise the book would fall down.
  • Air Resistance: The resistivity or drag in the air while an object moves is called Air Resistance.
    E.g.: When a parachutist open the parachute the movement slows down for the opposite force acting in it.
  • Upthrust: Upthrust force acts only on liquid or air. It pushes an object upwards inspite of gravity.
    E.g.: A helium balloon moves upwards due to up thrust force.
  • Magnetic: Magnetic force is the attraction force between the poles of magnets. N=S
  • Electrostatic: Electrostatic force is the attraction force between charges. +=-
  • Tension: The pull at both ends of a stretched spring ,string, or rope
  • Frictional force: the force produced when two objects slide one over another is called frictional force.
