1-Position your projectile launcher up. 2- Set at medium/short range 3- Take a meter stick and keep it parallel to the projectile launcher straight up from the plus symbol on the projectile launcher 4- Take 3 trials. As you fire the ball. Quickly notedown the position of the ball how far does it move up from the scale. 4- Take the average of your values. This is your h.
Two reasons: 1) It doesn't effect the timeperiod of the simple pendulum. 2) To make the catcher more massive so that it cannot move too far and thus you can record a suitable angle. The masses can be excluded as well but the catcher will become too light and it will shoot to fast. You won't be able to record a suitable angle.
Sir dont we have to find the the %diff bw the calculated muzzle velocity and the exact muzzle velocity?
Yes, you can. Bu the experiment requirement was to find between calculated muzzle velocity and initial velocity of ball
@@aaclassroom Thank you sir!
How to calculate h
1-Position your projectile launcher up.
2- Set at medium/short range
3- Take a meter stick and keep it parallel to the projectile launcher straight up from the plus symbol on the projectile launcher
4- Take 3 trials. As you fire the ball. Quickly notedown the position of the ball how far does it move up from the scale.
4- Take the average of your values. This is your h.
Nice lecture
Why some masses are attached at the end of catcher???.
Two reasons:
1) It doesn't effect the timeperiod of the simple pendulum.
2) To make the catcher more massive so that it cannot move too far and thus you can record a suitable angle. The masses can be excluded as well but the catcher will become too light and it will shoot to fast. You won't be able to record a suitable angle.
Thanks MAN 😊🙏😊
