Speed refers to how fast an object is moving. If you want to find the average speed, what do you need to know before you can begin calculations?
F
The amount of time it took to reach the destination.
G
The mass of the moving object and the surface upon which it is traveling.
H
The total distance the object traveled and the amount of time it took to reach the destination.
J
The mass of the moving object, the total distance it traveled, the amount of time, and the surface upon
which it traveled.

In a sample of oxygen gas at room temperature, the average kinetic energy of all the balls stays constant. which postulate of kinetic molecular theory best explains how this is possible? a. attractive forces between gas particles are negligible because the particles of an ideal gas are moving so quickly. b. collisions between gas particles are elastic; there is no net gain or loss of kinetic energy. c. gases consist of a large number of small particles, with a lot of space between the particles. d. gas particles are in constant, random motion, and higher kinetic energy means faster movement.
