APA 1161 Laboratory 5 - Newton’s Laws and Applied Biomechanics CORRECTOR TOTAL PART: 43 Marks Part A: Newton’s Laws of Motion 1 mark per question for Part A, except for Station 6, question 2 (no mark for answering whether or not they caught the penny) TOTAL PART A: 24 Marks Station 1 Perform a long jump with and without a 10-pound weight belt around your waist and measure how far you jump. Try to jump with the same amount of force both times. Which law(s) of motion was (were) explored with this activity? Newton’s second law In which situation did you jump farther? Condition without weight Explain your findings using the appropriate law(s) of motion. Mass and acceleration are inversely proportional so the greater the mass (when wearing weight belt), the less you accelerate and the shorter the distance travelled. Station 2 Throw a tennis ball using only your wrist and measure how far the ball travels. Repeat using your wrist and elbow. Repeat again using your wrist, elbow and shoulder. Which law(s) of motion was (were) explored with this activity? Newton’s second law In which situation did you throw the ball the farthest? Condition where wrist, elbow and shoulder were used. Explain your findings using the appropriate law(s) of motion. Force and acceleration are directly proportional so the greater the force applied (which takes place due to the greater range of motion of the arm), the greater the acceleration imparted to the ball and the further it will travel . Station 3 Slide a puck across different surfaces (artificial ice and wood) and try to get it to stop the same distance on each surface. Pay attention to how hard you have to release the puck in each case. Which law(s) of motion was (were) explored with this activity? Newton’s first law

APA 1161- Introduction to Biophysical Aspects of Human Movement University of Ottawa 2 Which surface required the most amount of force to reach the desired distance and why? The surface that required the most amount of force to reach a desired distance was the wood. This is because there was a greater amount of friction between this surface and the puck.

### What students are saying

• As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

• I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

• The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
