The Laws of Motion Worksheet

Instructions: For this assignment, describe Newton’s laws of motion while skateboarding. Next, study the graph of distance traveled to determine if the skateboarder is on a dry, wet, or muddy road condition. Describe how these conditions affect the motion of the skateboard. Then, complete the table by calculating the acceleration of the skateboard on each road condition.
Part 1: Newton’s Laws
Observe the virtual skateboarder coming down the hill and over the ramp. Describe how each of Newton’s laws of motion can be observed in this action. You can choose the dry, wet, or muddy conditions, or some combination of these.
Newton’s First Law of Motion
Newton’s Second Law of Motion
Newton’s Third Law of Motion
Part 2: Analyze
The graph below shows the distance traveled by the skateboarder on each of the different road conditions. Using the graph, determine which of the roads was dry, wet, or muddy. Explain your answer using complete sentences.

Road A
Road B
Road C
Part 3: Calculations
Using the given data table, calculate the acceleration of the skateboarder. You can use either form of the equation below.

Road A
Road B
Road C
Acceleration (m/s2)

Mass of person and skateboard (kg)
62
62
62
Force (N)
480
240
600
What would you expect to happen to the acceleration if all friction were removed from the ramp, making the net force even higher than 600 N?
