Force Problems with Motion Video Lessons

Concept

# Problem: You've just kicked a rock on the sidewalk and it is now sliding along the concrete. Draw a free body diagramDraw the force vectors with their tails at the dot. The orientation of your vectors will be graded. The exact length of your vectors will not be graded but the relative length of one to the other will be graded.

###### FREE Expert Solution

The forces acting on the rock are weight, normal force and friction.

Weight and normal force have equal magnitudes but opposite directions.
