Question

polling question what is the force that acts on an object and opposes its motion called? a. inertia b. thermal energy c. friction

Explanation:

Friction is a force that resists the relative motion of two surfaces in contact. Inertia is the tendency of an object to resist changes in its state of motion. Thermal energy is related to the temperature of an object and its internal energy. Normal force acts perpendicular to the surface of contact. The force that opposes an object's motion is friction.

Answer:

C. Friction
