Newton’s First Law

Practice

Do you think you understand Newton’s first law? Review Newton’s law and watch what happens to the skateboarder in the animation. Then answer the following questions:

  1. What is the motion in this picture?

  1. What is the unbalanced force in this picture?

  1. What happened to the skater in this picture?

Review

  1. State Newton’s first law of motion.

  1. You don’t need to push off with a foot against the ground to start a skateboard rolling down a bank. Does this violate Newton’s first law of motion? Why or why not?

  1. Nina ran into a rough patch of pavement, but she thought she could ride right over it. Instead, the skateboard stopped suddenly and Nina ended up on the ground. Explain what happened.

Practice problem to help students understand Newton's first law of motion[1]

  1. Now that you know about Newton’s first law of motion, how might you use it to ride a skateboard more safely?
