75 ! .drop the ball on the floor and observe its motion. identify all the energy forms associated with the ball at these times:

about to be dropped
falling down
hitting the floor
moving back up

The potential energy of the ball was converted to elastic energy. You can think of it as the mass of the ball being mounted to a spring that compresses when you hit the floor - but there will be some friction (both inside the ball, and particularly between the ball and the floor) which will dissipate energy:

it should be hittin the floor

Firstly, I am pretty sure "about to be dropped" has no energy form.

When it falls, gravitational energy occurs. When it hits the ground, the balls kinetic energy becomes potential energy due to the compression on impact with the ground. The it becomes kinetic energy once again as it bounces up to a certain degree.

Good luck!

where are the choice options?

water at room temperature is flowing through a pipe with pressure taps located 10 ft apart along one section of the pipe, which are connected to a mercury (s=13.6) manometer.
