Find a smooth surface that is positioned at an angle (a long board, a slide at a playground, a sloped driveway, etc.). Measure the distance from the starting point up the hill to the finishing point down the hill. Place a smooth running toy at the top of the hill, and let go. Measure the time it takes for the toy to roll down to the bottom of the hill. Repeat 4 more times. Use the middle of the 5 measurements for your calculations. Use the equation: a = g sin (q) to find the acceleration due to gravity. Off course you’ll need the equations of kinematics to determine the acceleration “a” first before finding g. Again compare your result to the actual value of 9.80 m/sec2 Then list 5 possible reasons why your result was different than the expected value. Data Time (in seconds) for 5 attempts: 3.5, 3.2, 3.8, 3.4, 3.7 Distance from starting point to end point: 9 feet Degree of the slide from which toy car rolls down: 45 degrees
