Question

Friction question about why a block slows down.

A) Because of gravitational force
B) Because of inertia
C) Due to the force of friction opposing its motion
D) Due to magnetic forces

Answer 1

Friction is an external force that opposes the motion of an object. The block slows down due to the force of friction opposing its motion.

Step-by-step explanation:

The block slows down due to the force of friction opposing its motion. Friction is an external force that acts opposite to the direction of motion. When a block slides across a horizontal floor, the friction force between the block and the floor opposes the motion of the block, causing it to slow down.
