A dishwasher is a machine that is used to clean dishware, cookware, and cutlery automatically. Unlike manual dishwashing, which relies heavily on physical scrubbing to remove soiling, the mechanical dishwasher cleans by spraying hot water, typically between 45 and 75 °C, at the dishes, with lower temperatures of water used for delicate items.
A washing machine is a home appliance used to wash laundry. The term is mostly applied to machines that use water as opposed to dry cleaning or ultrasonic cleaners. The user adds laundry detergent, which is sold in liquid, powder, or dehydrated sheet form, to the wash water.
A golf course is the grounds on which the sport of golf is played. It consists of a series of holes, each consisting of a tee box, a fairway, the rough and other hazards, and a green with a cylindrical hole in the ground, known as a "cup". The cup holds a flagstick, known as a "pin". A standard round of golf consists of 18 holes, and as such most courses contain 18 distinct holes; however, there are many 9-hole courses and some that have holes with shared fairways or greens. There are also courses with a non-standard number of holes, such as 12 or 14.

A tennis ball is a ball designed for the sport of tennis. Tennis balls are fluorescent yellow in organised competitions, but in recreational play can be virtually any color. Tennis balls are covered in a fibrous felt which modifies their aerodynamic properties, and each has a white curvilinear oval covering it.
Pressure washing or power washing is the use of high-pressure water spray to remove loose paint, mold, grime, dust, mud, and dirt from surfaces and objects such as buildings, vehicles and concrete surfaces. The volume of a mechanical pressure washer is expressed in gallons or liters per minute, often designed into the pump and not variable. The pressure, expressed in pounds per square inch, pascals, or bar, is designed into the pump but can be varied by adjusting the unloader valve. Machines that produce pressures from 750 to 30,000 psi or more are available.
Alfred Kärcher SE & Co. KG is a German family-owned company that operates worldwide and is known for its high-pressure cleaners, floor care equipment, parts cleaning systems, wash water treatment, military decontamination equipment and window vacuum cleaners.
A laundry ball or washing ball is a product made of solid, insoluble material promoted as a substitute for laundry detergent. Producers of laundry balls often make pseudoscientific claims about their mechanisms of action and exaggerate the extent of their benefits.
In fluid dynamics, flow separation or boundary layer separation is the detachment of a boundary layer from a surface into a wake.
A driving range is a facility or area where golfers can practice their golf swing. It can also be a recreational activity itself for amateur golfers or when enough time for a full game is not available. Many golf courses have a driving range attached and they are also found as stand-alone facilities, especially in urban areas. They are typically run by businesses or sometimes by universities. Distances are usually marked by target greens at regular distances. Driving ranges may have natural grass, similar to a golf course, or players may use synthetic mats that resemble real turf.
Window cleaning, or window washing, is the exterior cleaning of architectural glass used for structural, lighting, or decorative purposes. It can be done manually, using a variety of tools for cleaning and access. Technology is also employed and increasingly, automation.

The physics of a bouncing ball concerns the physical behaviour of bouncing balls, particularly its motion before, during, and after impact against the surface of another body. Several aspects of a bouncing ball's behaviour serve as an introduction to mechanics in high school or undergraduate level physics courses. However, the exact modelling of the behaviour is complex and of interest in sports engineering.
