why is force a vector

Newton's second law of motion gives a quantitative definition of force. Impulse Mathematical representation of Newton's second law of motion is or When the time of application of force is short then Ft is defined as impulse. Impulse is a large force acting for a s..

> If the scales selected for the representation of three vectors are the same, then, three equal vectors are represented by three arrows of equal lengths, pointing in the same direction. If, however, the scales chosen are different, then, it is possible to represent equal v..

Lorentz Force - The force experienced by a charged particle moving in space where both electric and magnetic field exist is called lorentz force. The lorentz force is therefore the vector sum of force due to electric field and the for..

Let us consider a single particle, whose position with reference to the origin O of the two-dimensional coordinate system is given by position vector . The location of the particle is P (x, y). Let q be the angle between OP and X-axis. Suppose a force applied on the particl..

A body on which two or more forces act is said to be in equilibrium if there is no change in its state of rest or of uniform motion. The condition necessary for equilibrium is that the vector sum of forces acting on the body should be zero. i.e., This also implies that..

Pushes or Pulls are very general names given to forces. A physicist is much more precise when describing forces acting on a body using terms like weight, frictional force, tension, normal reaction force, electrical force, magnetic force..

Force - A force is often defined as a "push" or a "pull". There is nothing untrue with this statement, but does not really tell you much about a force. Instead of defining force, it substitutes an antonym. A physicist prefers to define a force in te..
