Question 2

What does a steep slope in a potential energy vs. position diagram indicate about the force acting on a particle?

Question 3

If a particle is at a local maximum in a potential energy vs. position diagram, what can be inferred about its stability?

Question 4

In an energy bar chart, if the height of the kinetic energy bar decreases while the height of the potential energy bar increases, what does this indicate?

Question 5
