Introduction & Purpose:

Diagram:

Data:

 Trial Velocity (m/s) 1 1.759 2 1.760 3 1.751 4 1.767 5 1.755 6 1.744 7 1.760 8 1.759 9 1.767 10 1.748

 Maximum Velocity 1.767 m/s Minimum Velocity 1.744 m/s Average Velocity 1.757 m/s Table Height 0.91 m Actual Impact Point 0.755 m Maximum Impact Point Distance 0.761 m Minimum Impact Point Distance 0.752m Average Impact Point Distance 0.757 m

Discussion / Conclusion:

Questions:

1. Should you expect any numerical prediction based on experimental measurements to be exact? Would a range for the prediction be more appropriate? Explain.

2. Was your actual impact point between your minimum and maximum impact predictions? If so, your prediction was successful.

3. You accounted for variations in the velocity measurement in your range prediction. Are there other measurements you used which affect the range prediction? What are they?

4. Did you account for air resistance in your prediction? If so, how? If not, how would air resistance change the distance the ball flies?

5. Derive one equation for the horizontal and vertical coordinates of the ball’s motion in this experiment.

6. Derive a general formula for projectile motion with the object launched at an angle.
