Time-of-Flight henchman C. Control Box D. AC adapter E. Drop Box F. trade name lummox G. Solid gold lump H. Big plastic ball 3. Method Used 1) Place the steel ball on the slide down box. 2) Set the dater to Time Two Gates mode. 3) Measure the length between the bottom of the ball and the plate and record in panel 4) Release the ball using the timer switch and record the time it takes to fall. ) Change the distance and repeat step (4) until table is complete 6) fall back steps (3) (5) with solid golf game ball 7) Repeat steps (3) (5) with considerable plastic ball 4.

Gravity stayed constant through the whole experiment. Source of error could be due to measuring between ball and mat inaccurately. Answers to questions (1) Using our kinematics equations and the construct of a straight line (y=mx+b), show that the graphs made in part (7) should indeed be a straight line.What should the theoretical set for the cant and y-intercept be for this graph? (2) What are the actual values of the slope and y-intercept for the three graphs. Compare these to the theoretical values. Calculate the gravitational acceleration for all three balls from this information. (3) Comment on why the acceleration due to gravity is less for the plastic ball than the others. Give some ideas why you conceptualize this particular ball would behave like this and the other balls would not. The gravitational acceleration due to gravity is the same for every object, th e total acceleration is not.Acceleration is bring down a bit by the particular mass of the ball. In cases where m is large (like the steel ball and golf ball), the constituent will be small and therefore falling at almost the same acceleration. alone in the case where m is small (like the plastic hallow ball) the factor could be large, and therefore the balls acceleration could be significantly less due to the hollowness of the ball. Although the plastic ball is bigger in size, its mass is lighter. (4) A ball is thrown upward. epoch the ball is in the air, does its acceleration increase, decrease, or remain the same?Describe what happens to the velocity of the object from when it is thrown until when it returns. While in the air, the balls acceleration would remain the same. When the ball is thrown, its velocity is positive and lessen as its going up, and at the highest point, the velocity is zero. When its glide path back down, the velocity is negative and increasing. (5) Exp lain conceptually (without using equations) what the reach of Distance vs. Time would look like for a ball falling to the ground. Use kinematics to explain why it would be like this. The falling ball is moving at a constant rate ( 9. 80 ms-2 )
