Question

Please explain what do you mean by force in Physics ?​

Answer 1

→Force is physical push or pull on an object, which can result in the change of shape, size, direction or motion of an object.

→S.I. unit of force is Newton.

→ Newton's second law of motion gives the famous formula for determining force, that is :- F = ma, where, F is force, m is mass and a is acceleration.

→ Newton's third law of motion also tells us something more about force. That is, when we apply force on an object, the object applies equal force on us.

→ Force is generally of two types, contact and non-contact force, which is subdivided into many types. Some of them are :-

⇒ Gravitational Force :- Force applied by earth (gravity)

⇒ Electrostatic force :- Force applied by charges

⇒ Muscular force :- Force applied by muscles.

⇒ Frictional force :- Force applied by friction.

⇒ Air resistance force :- Force applied sue to the resistance of air.

⇒ Tension force :- Force applied by a string. (It is always a pulling force. It doesn't push any object)

Answer 2

Answer:

In physics, a force is an interaction that causes an affected object to be pushed or pulled in a certain direction.

Explanation:

There are basically four types of natural forces:

1. Gravitational force.

2. Electromagnetic force.

3. Strong nuclear force.

4. Weak nuclear force.
