Projectile+Motion+1

Using the Projectile Motion Simulation, determine where the object will land when launched horizontally at various heights by calculating the x distance using the "Big Four" kinematic equations as well as your knowledge of horizontal projectile motion and two-dimensional kinematics.

1. Make sure angle of the launcher is set to 0 degrees. 2. Make sure that the box labeled "air resistance" is unchecked. (Disregard air resistance) 3. Complete two sets using different launching objects, launch the object at three different heights for each set. 4. Measure y distances/heights using the movable tape measure provided in the simulation. 5. Use the "Big Four" equations to solve for the x distance. 6. Use the movable tape measure to place the target at your calculated distance. 7. Record your own calculations and the actual x distance, labeled "range" at the top of the simulation after firing, for percent difference.
 * __Data Collection Strategies__**

1. Does the x distance change depending on the mass and diameter of the object launched? Why? 2. What factors can cause error in your distance calculation? 3. For your first trial, what would the velocity be if measured at t=0.5 seconds? 4. Does the object travel farther if it is launched from a greater height?
 * __Analysis Questions__**

Create an x vs. y distance graph to display the relationship between the x and y components.
 * __Graphical Analysis__**

Calculate and record the percent difference between your distance calculations and the calculations provided by the simulation.
