what happens to the waves when water crashed into an obstacle?
the wave that crashes into the obstacle curls into itself like a cylinder and is forced down toward the bottom of the river. after it has hit the bottom, it turns upward again and meets the succeeding wave, which hits the obstacle and turns downward. In this way the wave moving upward splits. one part then moves in the direction of the current, another part in the opposite direction.
- why does something move?
- how can flowing water consume its momentum when it encounters an obstruction?
- why are the waves of descending rivers slower than the water flow of the river itself?
- why does a body move when something strikes it?
- under what conditions can a person on a see-saw not jump up?
- why does waves look like crescents when viewed from the side?
- what effects do the slope of the obstruction and the angle of impact have?
- why doesn't viscous water flow continually throungh a bent pipe?
- does the weight of water vary according to how one changes the slope of a pipe filled with water?
- how can one see that movement separates from its cause?
- where does the wave break?
- what causes cyclones?
