Question

List the three (3) types of contact forces.

a) Friction, magnetic, and gravitational
b) Tension, spring, and electrostatic
c) Normal, air resistance, and nuclear
d) Shear, torque, and centripetal

Answer 1

The three types of contact forces are tension, friction, and normal force, all of which arise from interatomic electric forces and result from physical contact between objects.

Step-by-step explanation:

The three types of contact forces are tension, friction, and normal force. These forces result from the interaction of one object touching another and are due to interatomic electric forces on a microscopic level. Another example is the force exerted by a spring, which is also considered a contact force. It's important to note that buoyant forces are considered contact forces in fluids and that magnetic, gravitational, and nuclear forces are not contact forces but long-distance or field forces.
