Chemistry Ch 1 Test - Missed Questions

Ms. S set up an experiment to see how the mass of a ball affects the distance it rolls off a ramp. What is the dependent variable?

• Distance traveled by the ball
• Height of the ramp
• Mass of the ball
• Where the experiment took place.

"For a collision occurring between object 1 and object 2 in an isolated system, the total momentum of the two objects before the collision is equal to the total momentum of the two objects after the collision." Is this a theory or a law?
