true/false. the behavior of a gas in a closed container is affected by the number of gas particles (atoms), the size of the container, and the average kinetic (temperature).
thermometer. Temperature has to do with the average kinetic energy of molecules, and we find it with a thermometer
Kinetic energy is equal to potential energy during the change
You don't have enough information in this case. Kinetic energy depends on mass and speed. Speed can be calculated as distance / time - and no time is given, nor is there any other information that allows you to calculate the time. Note that even if time is given, you can calculate the average (mean) speed, but that will only give you a rough idea of the mean kinetic energy. In this problem, if the speed changes a lot, the average kinetic energy (averaged over time) will be greater than in the case of a constant speed. This is because kinetic energy is proportional to the square of the speed.
1) measure its mass and velocity. 2) Measure where its falling from. (the kinetic energy will equal the potential energy up to the instant the nickel stops).
If you mean kinetic energy, you'll find it everywhere where there is movement.

kinetic energy is the energy possessed by a body by virtue of its motion. So you can find kinetic energy in a car,in a ball falling due to the earth's pull,yourself while walking etc
Your hand cannot find the average kinetic energy of the particles in an object.
Kinetic energy is equal to potential energy during the change
The answer depends on what two (or more) things the ratio is meant to compare. The kinetic energy of several objects? The kinetic energy of an object compared to its total energy? The kinetic energy compared to its engine size?
Heat is just the measure of the average kinetic energy of the molecules in... whatever you are measuring. Kinetic energy is s form of energy, so the fact that the molecules have kinetic energy proves heat is energy. Also heat powered engines do work by converting heat into kinetic energy. ============================ Thanks for that. But how do you prove that heat is a form of energy ? ============================
A roller coaster is a good example for a place to find both kinetic and potential energy. Before a drop, it has potential energy. At the end of a drop, it has kinetic energy. Half way through the drop, it has kinetic and potential energy at the same time.
By calculating and adding its kinetic energy and its potential energy.

Mechanical energy is potential energy plus kinetic energy. ~A.L.C.
because there are greater spaces between its molecules hence they have more room to move around. Kinetic energy is the energy of motion therefore, since gas molecules can move around more freely, they have the greatest kinetic energy.
