My assumptions about Energy loss in experiment
In my assumption, there are 4 points where the energy loss occurs.
1. The air resistance when the golf club is swinging.
2. The air resistance when the ball is flying
3. At the pivot point, due to friction with the pivot
4. Energy loss due to an inelastic collision between the golf ball and the golf club
In the assumption, I supposed that the air resistnace when golf club is swinging and the air resistance when the ball is flying are negligible. Because in the experiment, the distance travelled by the ball is not long enough to cause a significant air resistnace, and the duration of swinging motion of golf club is relatively short to cause a significant air resistance and the shape of golf club does not tend to cause the air resistnace very much.Therefore the most energy loss will be caused by the friction force acting between the Iron stick holder and golf club, and the non elastic …show more content…
Whereas I assume that an inelastic collision between the golf club and golf club will be significantly affected by the loft angle, because inelastic collosion is directly related to the location of contact area or the size of contact area might highly depend on the loft angle of golf club.
Also, in my assumption, the energy loss of gravitational potential energy includes both energy loss due to inelastic collision and energy loss due to friction at the pivot. In order to find the energy loss due to non-elastic collision only, the swing of golf club without a golf ball is analyzed. If there is no ball, the friction at the pivot will be only the consideration of energy loss.
If I represent this situation with equation:
Ep loss by inelastic collision = Ep total lost – Ep loss by friction at the
