Answer 1

$\huge\mathfrak\red{⚫Be Brainly ⚫}$

Answer:

The force of friction always opposes motion or the tendency of motion.

Answer 2

Answer:

I think friction does not supports the motion always because it's the opposite force acting between two surfaces which actually oppose the motion.

Types of frictional forces:

1.kinetic: when body is in motion

2. Static: when body is at rest (frictional force is higher than external force)

3. Limiting: when body is about to move
