Which form of energy is represented by a book lying on a desk? Which form of energy is represented by a book falling off a desk?
Julia AguilarThe book lying on a desk has potential energy; the book falling off a desk has kinetic energy.
Potential energy is the energy that a body has because of its state or position.
The energy that a body has as a result of motion or movement is known as kinetic energy.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.

- How much work would it take to push a # 1 kg # weight up a # 9 m # plane that is at an incline of # (5pi) / 12 #?
- A ball with a mass of #70 g# is projected vertically by a spring loaded contraption. The spring in the contraption has a spring constant of #19 (kg)/s^2# and was compressed by #7/6 m# when the ball was released. How high will the ball go?
- A wrench with a length of #35 cm# is being used to unscrew a #7/2 cm# bolt. If a torque of #36 Nm# is needed to overcome the friction keeping the bolt in place, what is the minimum torque that must be applied to the wrench to unscrew the bolt?
- A wrench with a length of #42 cm# is being used to unscrew a #7/2 cm# bolt. If a torque of #42 N*m# is needed to overcome the friction keeping the bolt in place, what is the minimum torque that must be applied to the wrench to unscrew the bolt?
- An object with a mass of #8 kg# is hanging from an axle with a radius of #27 cm#. If the wheel attached to the axle has a radius of #18 cm#, how much work would it take to turn the wheel a length equal to the circumference of the axle?
