Casters and bearings reduce friction and make it easier to move heavy objects by allowing them to roll smoothly on wheels or balls. This design helps distribute the weight evenly, making it more efficient to push or pull the object.
Casters are the wheels attached to the bottom of a chair that allow it to move easily across the floor. They affect the chair's mobility by enabling it to roll smoothly in different directions. The type and quality of casters can impact the chair's functionality by determining how well it moves on different surfaces and how stable it is when in use.
The use of force to move an object some distance is called work. Work is calculated by multiplying the force applied to an object by the distance the object moves in the direction of the force. Work is measured in joules.
When you use a shovel to pry up an object, the ground acts as a fulcrum. A fulcrum is a fixed point around which a lever pivots to lift or move an object. In this case, the ground provides the support and resistance needed to pry up the object using the shovel as a lever.
To move an object using force, you need to exert a push or a pull on the object. This force can be applied through direct contact or through mechanisms like levers or pulleys. The magnitude and direction of the force applied determine how the object moves.
A door is an object that often requires a significant amount of force to open or close, especially when it's stuck or jammed.
Use a shopping cart for an example, the rear casters (wheels) are fixed, the front casters are steering casters.
The best types of table legs with casters for easy mobility and versatility are typically adjustable height legs with locking casters. These legs allow you to easily move the table around and adjust its height to suit different needs. Locking casters ensure stability when the table is in use.

To attach casters to plywood effectively, use screws or bolts to secure the casters to the corners of the plywood. Make sure to choose casters that are the appropriate size and weight capacity for your project. Additionally, consider using washers or reinforcement plates for added stability.

You could use compressed air to move an object you are not touching. You could also put an object on a table and lift one edge of the table which would cause the object to move. You could also use more complex means, such as magnets. Of course you could tie a rope around an object and pull it and you’d be moving it without touching it.
The use of wood casters on furniture began to decline in the mid-20th century, particularly as metal and plastic casters became more popular due to their durability and functionality. While there is no specific year marking the complete cessation of wood casters, by the 1970s, most furniture manufacturers had largely transitioned to these modern materials. Today, wood casters are rare and typically found only on vintage or traditional pieces.
Swivel casters are found on many pieces of furniture, particularly around the office and in industrial kitchens. They are most commonly used on office chairs.
