Data

Record the distance traveled for each of the trials for the three floor surfaces in the table below.

Distance Object Traveled
Floor Surface Trial 1 Trial 2 Trial 3




Data Analysis

Calculate the average distance traveled for each floor surface. Use the following guidelines for calculating averages, and show your work.

Floor Covering Calculation of the Average Average Distance Traveled
Example (trial 1 measurement + trial 2 measurement + trial 3 measurement) / 3 (number of trials) Your answer from the calculation, showing the average distance the ball rolled for that floor covering.

Answer 1

Frictional force is reduced in smooth surfaces but is large in rough surfaces.

What is Force?

Force is defined as an agent which causes a change in the motion or state of an object.

Forces are of two types:

• Contact forces and
• Non-contact forces

Contact forces include frictional force.

Frictional forces refers to the force which acts between two surfaces in contact by opposing the relative motion of one over the other

Frictional force depends on the nature of surfaces in contact where rough surfaces produce greater frictional force than smooth surfaces.

Therefore, frictional force is reduced in smooth surfaces but is large in rough surfaces.
