WebTypes of Forces. Constant force:- The force whose magnitude and direction do not change throughout the motion of the body is called constant force.Examples of constant forces are kinetic friction force, hydrostatic force, weight, etc. Variable force:- The force whose magnitude and direction changes during the motion of the body is called Variable force. WebThe second law describes what happens when the forces acting on a body are unbalanced (a resultant force acts). The body changes its velocity, v, in the direction of the force, F, at a rate proportional to the force and inversely proportional to its mass, m. The rate of change of v is proportional to F / m. psychology today office space
