Charlie is investigating friction. she will use the same amount of force to push two wooden balls across two level surfaces. then she will record her results in the table below. which prediction will most likely describe how friction will affect her findings?
a. the distance for trial 3 will be greater than the distance for trial 1 partly because the weight difference of the balls will affect friction.
b. the distance for trial 2 will be greater than the distance for trial 1 because the difference in surface roughness will affect friction.
c. the distance for trial 4 will be greater than the distance for trial 2 partly because the weight difference of the balls will affect friction.
d. the distance for trial 3 will be greater than the distance for trial 4 because the difference in surface roughness will affect friction.
