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.
