have two rougher surfaces

increase thee area of the surfaces

Question 6

smoother surfaces
using rollers
reduce contact area
lubrication

Question 7

Answer 7

two forces that are equal in size

Question 8

what is an unblaced force

Answer 8

an object that has two forces that are un equal in size

Question 9

what is newtons first law say

Answer 9

an object will remain at rest or travel at a constant speed in a straight line if the forces are balanced
