Force In physics, a force is any influence that, when unopposed, will change the motion of an object. A force can cause an object with mass to change its velocity (which includes to begin moving from a state of rest), i.e., to accelerate. Load A weight or source of pressure borne ...
Force is everywhere and it comes in a variety of sizes, directions, and type. We can define Force as the push or pull of an object. Learn Force definition, unit & types of Force with solved examples.

What is a force pair? Newton's Laws of Motion: Sir. Isaac Newton's three laws of motion form the foundation for the field of physics known as classical mechanics. The first law states that an object at rest or in linear motion stays at rest or in linear motion unless acted upon by ...
In physics, flux is a measure of the number of electric or magnetic field lines passing through a surface in a given amount time. Field lines provide a mechanism for visualizing the magnitude and direction of the field being measured. They are imaginary lines that follow different patterns, dep...
