What is Force:-
A force is any influence that causes an object to undergo a certain change, either concerning its movement, direction, or geometrical construction. In other words, 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, or a flexible object to deform, or both.
Related concepts to force include:
1.Thrust, which increases the velocity of an object;
2.Drag, which decreases the velocity of an object;
3.Torque:-which produces changes in rotational speed of an object. In an extended body, each part usually applies forces on the adjacent parts; the distribution of such forces through the body is the so-called mechanical stress. Pressure is a simple type of stress. Stress usually causesdeformation of solid materials, or flow in fluids.
