The Laws of Motion Worksheet Name: 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 […]
