Question

What do you understand by a force ?

Answer 1

Hint: A pull or push on an object is referred to as force. An object will accelerate, slow down, stay in place, or change shape as a result of a force.

Complete answer:
A force is any interaction that, while unopposed, causes an entity to change its motion. A force may cause an object with mass to change its velocity (which involves starting to move from a standstill), that is, to accelerate.Accurately, the force can be defined as a push or a pull. A force is a vector quantity since it has both magnitude and direction.

We shall look into a few examples of fundamental forces in real life. In the atomic nucleus, the strong nuclear force binds both the protons and the neutrons together. The electromagnetic force is a force that causes opposite electric charges to attract, including electric charges to repel and magnets to pull.

In everyday life, non-fundamental forces are experienced. The normal force behaves in a direction that is normal to the object-surface interaction. Friction is a force on surfaces that opposes motion. Elastic forces and friction forces, as well as frame-dependent forces such as centrifugal forces and Coriolis forces, are examples of non-fundamental forces.

Note: Any of the four fundamental forces, which are gravitational, electromagnetic, strong, and weak forces, are those that control how objects or particles interact and how those particles decay. It is referred to as a fundamental force. All known natural forces can be traced back to these fundamental forces.
