The equation for the change in the position of a train (measured in units of length) is given by the following expression: x = ½ at² + bt³ where a and b are constants and t is time (measured in units of time).

Sully uses a battery and a coil of wire to create an electromagnet. Using the same materials, if he wants to increase the strength of his electromagnet, he must the number of loops in the coil of wire along its length.

The boys tried a second experiment. They built a balloon car like the one seen here. As the gas in the balloon is released, the car moves. Ben and Dylan discovered that the bigger they blew up the balloon, the farther the car moved.

In the process of making lead shot, molten lead is drippedinto water. The lead forms small drops that harden to formthe shot. The specific heat of the shot can be approximatedas the same for both the solid and molten lead. If 0.

You are jumping on a trampoline and it occurs to you that energy is being transferred as you bounce. ( ... sounds like your usual thoughts, doesn't it?) You realize that sometimes you do work on the trampoline and sometimes it does work on you.
