Category: Force

Newton’s First Law of Motion (Inertia) An object at rest remains at rest, and an object in motion remains in motion at constant speed and in a straight line unless acted on by an unbalanced force

Some examples of force are Nuclear force, gravitational force, Frictional force, magnetic force, electrostatic force, spring force and so on.

The basic equation of force is F = ma which states that the net force acting on an object is equal to the product of mass and acceleration. In short, it is force equals mass times acceleration.

A force is a push or pull upon an object resulting from the object’s interaction with another object. Whenever there is an interaction between two objects, there is a force upon each of the objects. When the interaction ceases, the two objects no longer experience the force.

The SI unit of force is the newton, symbol N. The base units relevant to force are: The metre, unit of length — symbol m. The kilogram, unit of mass — symbol kg. The second, unit of time — symbol s.

Name the various types of forces.

In Physics, force is defined as: The push or pull on an object with mass causes it to change its velocity. Force is an external agent capable of changing a body’s state of rest or motion. It has a magnitude and a direction.
