A wheel and axle is a simple machine composed of a wheel attached to a smaller axle, enabling the transfer of force to accomplish tasks like lifting or moving objects more efficiently. Types of Wheel and Axle Machines The wheel and axle have come a long way since the first potter’s wheel in Mesopotamia. Today, …
Levers are simple machines made of a beam balanced on a support called a fulcrum. They are divided into three types—first, second, and third class—based on the positions of the force, fulcrum, and load. In first class levers, the fulcrum is in the center, with the force on one side and the load on the …
Many forces familiar to us operate in a linear fashion. For example, a car moving on a straight road. Forces are the subject of linear kinematics, an area that studies objects whose motion takes place in a straight line. However, torque forces act differently from this. They are rotational forces with a turning effect, making …
DEFINITION: Concurrent forces are multiple forces acting on a single point or object, where their lines of action intersect at a common point, resulting in a combined effect on the object. EXPLANATION: From mashing potatoes in the kitchen and typing on a keyboard to using a crane to lift heavy construction materials, we apply force …
We rely on machines and devices to carry out various tasks in our day-to-day lives. These machines and devices feature electronic circuits that enable them to carry out the tasks they are designed to. Combination logic circuits are just one type of circuit that is featured in many devices and machines that we use daily. …
Triangles, squares, and circles are some of the basic shapes we encounter in our day-to-day images. They have length and width and completely enclose a space. They are referred to as two-dimensional (2D) shapes because they only have two dimensions (measurable features) i.e. length and width. Three-dimensional shapes are those that have three measurable features …
An algorithm refers to a sequence of steps taken in order to complete a given task or solve a problem. It gives detailed guidelines with precise step-by-step instructions. They involve a process of computation with an initial step (often called an input) and end with a desired given result. For example, a computer program is …
One of the most thrilling encounters with ellipses is in a room of the National Statuary Hall of Washington D. C. The oval-shaped room introduces you to a whispering chamber where sound can travel along the walls in a unique way due to its elliptical shape. Ellipses are special figures resembling circles. They are like …
In mathematics, shapes can be transformed in different ways to create new positions or orientations on a plane. These transformations include reflection, translation, dilation, and rotation, each describing a unique kind of movement or change. Today, we focus on reflection and how it appears in everyday life. A reflection is a transformation that flips a …
Energy is the capacity to do work. It plays a vital role in modern life, driving many of our technological and industrial processes. Energy comes in different forms, including: Chemical energy Mechanical energy Heat energy Sound energy Electrical energy Radiant (light) energy Nuclear energy Tide energy Depending on the type of work you want to …
