In sports, where does the $kinetic energy$ that people use to move primarily originate?

A car of mass $m$ moves with speed $v$ at the top of a vertical loop. What is the kinetic energy $K$ of the car at the top of the loop?

Which of the following is the correct equation for the gravitational potential energy of an object near Earth's surface?

Water stored behind a dam is an example of what type of energy?

In the context of kinetic energy ($E=\frac{1}{2}m{v}^2$) and stopping a moving object, what is the key factor to achieving a smooth stop?

When is an object's $KE$ at its maximum?

A $2\mathrm{kg}$ object is held at a height of $5m$ above the ground. If the acceleration due to gravity is $g=9.8m/s^2$, how much gravitational potential energy does the object have relative to the ground?

Which of the following is an example of $kinetic energy$?

Which of the following statements is true about a car moving with constant $v$?

When you pull a child in a wagon across a level surface, is work done on the wagon by the force you apply?$W=Fda0cos8$

A gas undergoes a process from state 1 to state 3, during which the pressure remains constant at $2.0\times 105^{}\mathrm{Pa}$ and the volume increases from $1.0m^3$ to $3.0m^3$. Calculate the total work done by the gas during this process, in kilojoules ($\mathrm{kJ}$).

In the context of energy, what type of energy is stored for later use?

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