Question

Which force resistant motion when objects are in contact
Inertia
gravity
friction
applied

Answer 1

The force that resists motion when objects are in contact is **friction**. Friction acts to oppose the relative motion between two surfaces in contact. Inertia refers to the tendency of an object to resist changes in its state of motion, while gravity is a force that attracts objects towards one another based on their mass. Applied force is an external force applied to an object, which may overcome friction to cause movement.
