Force➫ Any interaction that when unopposed will change the motion of an object.
♦ It's SI unit is Newton (N).
♦ It's formula is F = m × a.
♦ It has both magnitude & direction, making it a vector quantity.
♦ It can cause an object with mass to change its velocity to accelerate.
➊❭ Effects 0f Force are:-
▬▬▬▬▬▬▬▬▬▬▬▬▬⤵
❱ It can make a stationary object move or change its position of rest.
♦Ex:- When you kick a stationary Football it will in motion.
❱ It can change the speed of a moving object.
♦Ex:- When goalkeeper applies force to stop the football.
❱ It can change the direction of motion of a moving object.
♦Ex:- When a batsman hits a ball.
❱ It can change the shape or size of an object.
♦Ex:- When you squeeze a sponge.
❷❭ Types 0f Force are:-
▬▬▬▬▬▬▬▬▬▬▬▬▬⤵
❲1❳ Contact Force➫ A force that acts only when it is in contact with an object.
♦Ex:- Pushing a car up a hill.
❱ Types 0f Contact Force:-
▬▬▬▬▬▬▬▬▬▬▬▬▬⤵
❱ Muscular➾ The force which is exerted by the muscle of your body.
♦Ex:- When you lift your School's Bag.
❱ Frictional➾ The force generated by two surfaces that contacts & slide against each other.
♦Ex:- A person sliding down a slide.
❲2❳ Non-Contact Force➫ A force that acts on an object without being in contact with it.
♦Ex:- Leaves falling from a tree.
❱ Types 0f Non-Contact Force:-
▬▬▬▬▬▬▬▬▬▬▬▬▬⤵
❱ Gravitational➾ A force that attracts any two objects with mass.
♦Ex:- Leaves falling from trees.
❱ Magnetic➾ The force that arises due to the motion of charged particle within the magnetic field.
♦Ex:- Iron pin attracted to magnet.
❱ Electrostatic➾ The attraction or repulsion of particles or objects because of their electric charge.
♦Ex:- When you rub a comb in hair.
