Part I - Newton's First Law Make sure the boxes that say "Force" and "Speed" are checked.

a. Apply a force of 50 N right to the box. Describe the motion of the box using physics terms (i.e. velocity, acceleration, displacement). Refer to the speedometer in your answer.

b. Reset the scenario (don't forget to check force, speed again). Apply a force of 50 N to the right for about 5 seconds then reduce the applied force to zero (the man should stop pushing). Don't reset the scenario. Describe the motion of the box. Refer to the speedometer in your answer.

c. Apply a force of 50N to the left. Describe the motion of the box.

d. Explain the exact steps needed to make the box come to a stop.

Summary

Newton's First Law of Motion States "An object at rest stays at rest and an object in motion stays in motion with the same speed and in the same direction unless acted upon by an unbalanced force." Explain how your observations in a - d support this Law.

Part II - Newton's Second Law

a. Reset the sim, don't forget to check force, speed again. Remove the box and place a garbage can on top of the skateboard. Using your partner's iPad, measure the amount of time it takes to reach maximum speed using a force of 50 N. Try this again with forces of 100N, and 200N.

Applied Force

Time To Max Speed

b. Reset the sim, don't forget to check force, speed again. Remove the box and place a garbage can on top of the skateboard. Using your partner's iPad, measure the amount of time it takes to reach maximum speed. Try this with a refrigerator, and a crate. Record your findings

Summary

Newton's Second Law states "The acceleration of an object as produced by a net force is directly proportional to the magnitude of the net force, in the same direction as the net force, and inversely proportional to the mass of the object." Explain how your observations in both a and b support this Law.
