7 questions

1

Define friction in your own words, explaining how it affects an object's motion on a slope.

2

Imagine a block on an inclined plane. List the forces acting on the block, and identify which force opposes its motion down the plane.

Quick comprehension check

A block is sliding down a ramp at a constant speed. If the force of gravity pulling the block down the ramp is 10 N, what is the magnitude and direction of the friction force acting on the block? A box is pushed up a ramp with an applied force of 25 N. If the friction force acting on the box is 8 N, what is the net force acting on the box along the ramp? In what direction does friction act?
