1. I bowl in a 10 pin bowling league once a week. It's all the bowling I do but there are others in the league that bowl 3-4 times a week. We had a bit of a argument going on the other day. Here's the skinny...

Bowling pins on average weigh 3.5 lbs. Bowling balls weigh between 14-16 lbs. So if one player throws a 14 pounder and the other a 16 with the same speed and each ball hits a single pin at the same angle, will the lighter ball deflect more to one side than the heavier would?

This came up because no matter how hard you throw a ball at 10 pins, bowlers can still end up with the same pins configurations once ball (First shot) has made contact and passed through. Doesn't seem to make much difference how hard one throws IOW. Although a lighter ball seems more prone to unfavourable pins left over (Splits) for the second shot (spare shot). People argue that a heavier ball deflects less than a lighter ball.. Is this true?

edit: last line

Yes. The more massive ball will be deflected slightly less.

Is that because the pin or the ball compresses a bit upon impact?

It's because the ratio of ball mass to pin mass is greater for the heavier ball than it is for the lighter ball. Imagine that it was a ping pong ball moving at the same speed hitting the pin. The pin would barely budge, while the ping pong ball would defect a great deal.
Go in the total opposite direction and imagine a ball with the mass of a city bus, and you would be hard pressed to notice any deflection on the part of the ball. It would knock the pin out of the way almost as if it wasn't even there. The difference between light bowling ball vs. heavy bowling ball just falls along this line of progression.

Thanks. I like the bus analogy.

Curious.... if I fire a photon at a flat surface from a 45° angle will it bounce off at the same angle? I know I can’t fire an electron at c but if I could get close to c utilizing same method, would the electron act in the same manner as the photon?

I’m thinking the electron would break apart and if that is true, is there a speed I could fire the electron at to mimic the photon striking the flat surface?

7. 1) Electrons won't break apart, they are elementary particles.
2) what happens depends on the energy of the photon or electron. Look up diffraction and the photoelectric effect.

Doh! I hate repeating mistakes.!
