Question 8(Multiple Choice Worth 2 points) (05.06 MC)

Jon is designing an experiment to see the effect of mechanical energy on the number of times a ball bounces. Why is it important that Jon keeps detailed records of his experiment?

The records will show how bouncy the ball is.
The evidence produced by his experiment should be replicable by others.
The evidence produced by the experiment will prove that he is a good scientist.
The records will prove that the mechanical energy of the ball will change with height

If a sphere and a cure have the same mass and are propelled up a ramp with the same force, which would travel father up the ramp? explain.

If the ama of the inclined plane below is 2, calculate the ima and efficiency. ima = efficiency =

When temperature of a substance increases, of its particles increase resulting in more between particles. real world applications of thermal expansion absolute zero (-273 degrees c) is the lowest possible temperature on the kelvin scale. it is a measure of where a substance has no kinetic energy. heat is a process of the . energy flows spontaneously from a object to a until equilibrium is reached. heat is measured in heat is transferred throughis a method of heat transfer that occurs between particles of matter that are in direct contact with each other. are poor conductors that impede / reduce the rate of heat transfer. is a method of heat transfer that occurs in fluids (non-solids) by means of currents. real world application of convectiona method of heat transfer through electromagnetic waves. when energy moves from one object to another inside a closed system, no energy is or in the system in the transaction. systems will spontaneously move to a state of organized energy or high disorder over time called
