Question

Information about force,kinds of force,unit of force,etc

Answer 1

Hey,,
Force is any physical cause that tends to change the motion of a body either at rest or in motion.
It's types are- Gravitational force, tensional force, normal force, frictional force, air resistance force, force applied through strings, etc..
Unit of force is Newton(N).
Hope this helps you!!

Force➫ Any interaction that when unopposed will change the motion of an object.

♦ It's SI unit is Newton (N).

♦ 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.
