Types of Forces Static friction Frictional force between surfaces at rest with respect to each other. It increases with increasing applied force up to a maximum value (which is proportional to normal contact force). Kinetic friction Frictional force acting between surfaces in relative motion. Viscous forces Resistive force experienced by a solid moving in a fluid.
[accordions autoHeight='true'] [accordion title="1. Newton's Laws of Motion"] Newton's First Law: a body will remain in its state of rest or uniform motion in a straight line unless acted upon by a resultant force. Newton's Second Law: the rate of change of momentum of a body is proportional to the resultant force acting on it and the
