In the lab, you will be investigating the properties of projectile motion. The experiments are similar to those described in section 4-6 of the text, with the added complication that (in the lab) the projectile lands lower than where it started. The general principles of projectile motion still apply, however.
For a projectile that starts and ends at the same height, use simulation 1 to help fill in the table below, or you can simply calculate the values yourself. Note that the simulation does not stop until the ball's y-coordinate goes slightly negative, but that should not introduce too much error. The initial speed is 20 m/s.
|Launch Angle||vox (m/s)||voy (m/s)||Time of flight (s)||Range (m)|
For the next part, use a launch angle of 30 degrees. Circle TRUE or FALSE for the following statements. Use the simulations if you need help. In simulation 1 you can vary the initial velocity and the launch angle, while in simulation 2 you can vary the x and y components of the initial velocity.
|Keeping vo fixed but increasing the launch angle by 5 degrees will increase the time of flight.||TRUE||FALSE|
|Keeping vo fixed but increasing the launch angle by 5 degrees will increase the range.||TRUE||FALSE|
|Keeping voy fixed and increasing voxwill increase the time of flight.||TRUE||FALSE|
|Keeping vox fixed and increasing voy will increase the time of flight.||TRUE||FALSE|
|Keeping vox fixed and increasing voy will increase the range.||TRUE||FALSE|
