My teacher wants us to make something about energy. for instance define kinetic energy. then we need to build something that represents it. in a past time i did volume and used a graduated cyclometer that i filled up with water and froze. this unit is energy, so anything that has to do with energy. give me a few ideas on what i can do as well as where i can find the supplies! before the weekend (first weekend in march) urgent! best idea will get brainest and a !

A-of 75 cm by cm by 17.5 cm up. of is 2 kg a , in ,if it is in , kg/?

At a certain instant after jumping from the airplane a, a skydiver b is in the position shown and has reached a terminal (constant) speed vb = 52 m/s. the airplane has the same constant speed va = 52 m/s, and after a period of level flight is just beginning to follow the circular path shown of radius ρa = 2330 m. (a) determine the velocity and acceleration of the airplane relative to the skydiver. (b) determine the time rate of change of the speed vr of the airplane and the radius of curvature ρr of its path, both as observed by the nonrotating skydiver.

An object dropped from cliff falls with a constant acceleration of 10 metre per second square find its speed of two seconds after it was dropped
