Purpose: The idea of this lab was to expand our knowledge of how speed can be affected in certain conditions. In the first lab we ventured into the thought of determining the speed of a projectile. In the next station we learned how weights affect speed in an incline plane. In the last lab we learned about friction and how it affects speed with the more friction there is. Station 1: Speed of a projectile Procedure: At this station the materials being used are a dart gun, protractor and a tape measure. With the dart gun we learned to determine the initial velocity of the dart leaving the gun. The next part was to determine the angle at which the dart would hit the stool using our knowledge of projectile motion. The catch is that it couldn’t be pointed down. The gun had to be either horizontal or pointed at an angle upwards. Calculations and Results: Here we determined the height at which the dart was from the ground this later will be used as our Y. The other distance was in the X direction and that will be used as our horizontal. The Y was 56cm and the X was 190cm.The equations used to determine the angle at which it is required to hit the spot were as follows: ∆x=Vi(cosθ) ∆t The angle we found was zero. We determined that the dart fell 41 cm because of gravity by using the equation below. Vy,f=-g∆t Conclusion: To determine the initial velocity we figure that there had to be a starting point and a time it took to get from the starting point to the board was the final velocity. The initial velocity was the point at which we started and the object was at rest so we found the initial velocity to be 0m/s. Hitting the stool or the a point on the board in our case, was determined by mostly trial and error mostly because of the lacking time we had.
