Projectile Motion Experiment
Aim: Determine the initial velocity of a projectile fired from a potato gun. Method:
1. Set the gun to a predetermined angle. 2. Charge the gun with a predetermined amount of propellant. 3. Fire the gun and record the projectile’s total time of flight. 4. Measure the range of the projectile.
Results:
Angle of the gun: Type of propellent: Amount of propellent: Range (m) Time of flight (s)
Average Range: Average Time of flight: Calculated Initial Velocity:
Conclusion1:
1
Try to determine the initial velocity more accurately by using the simulator with air resistance at

Projectile Motion Experiment
Aim: Observe the affect of the gun’s angle on the projectile’s time of flight and
range.
Method:
1. Set the gun to a predetermined angle. 2. Charge the gun with a predetermined amount of propellant. 3. Fire the gun and record the projectile’s total time of flight. 4. Measure the range of the projectile. 5. Increase the angle of the gun and repeat the procedure.
Results:
Type of propellent: Amount of propellent: Initial Velocity: Angle of the gun Range (m) Time of flight (s)
Conclusion:
