9. Work & Energy

Which statement best describes the difference between $\mathrm{potential energy}$ and $\mathrm{kinetic energy}$?

Which of the following pairs correctly identifies an example of $\mathrm{kinetic} \mathrm{energy}$ and an example of $\mathrm{potential} \mathrm{energy}$ found in a typical home?

Which form of energy does a car's engine primarily convert into $\mathrm{mechanical} \mathrm{energy}$?

A string is wrapped around a uniform disk of mass $M$ and radius $R$. The disk is initially at rest and is free to rotate about its central axis. If the string is pulled with a constant force $F$ causing the disk to rotate without slipping, what is the kinetic energy of the disk after the string has unwound a length $L$?

Which topic in a biology textbook is directly related to the concept of $\mathrm{kinetic} \mathrm{energy}$ in physics?

Which statement best describes the relationship between $\mathrm{work}$ and $\mathrm{energy}$ in physics?

$$In a simple pendulum undergoing oscillatory motion, which moment corresponds to the maximum kinetic energy of the system?$$

Which type of energy is considered stored energy due to the interactions between particles or objects?

When analyzing a physical situation using energy methods, which objects should be included in the system for the analysis?

When a toaster operates, into what forms of energy does it primarily convert $\mathrm{electrical} \mathrm{energy}$?

In the context of a frictionless slide, how does increasing the starting height of an object affect its final speed at the bottom, assuming it starts from rest?

What type of energy is considered stored energy?

Which of the following best defines energy?

A car of mass $m$ starts from rest at the top of a frictionless hill of height $h$. What is the car's speed after coasting down the other side to the bottom of the hill?

Which of these features is true of both solar and wind power?
