A constant force refers to a force that has a consistent magnitude and direction throughout its action on an object. This means that there are no changes in either intensity or direction while applying this force.
Net force refers to the sum total of all forces acting on an object and determines its overall motion.
Frictional Force: Frictional force opposes motion between two surfaces in contact and depends on factors like surface roughness and normal force.
Tension Force: Tension force arises when an object pulls or stretches another object through tension in a string, rope, or cable.
