How did the universe come into being? What is its age? What is it made of? How does it work? What is the fate of the universe? These are questions each one of us has asked at some point in life. Interestingly, scientists have joined together to satisfy our curiosity regarding the world around us. …
Concentration gradient is a term commonly used in biology and physical chemistry to describe the difference in concentration of a solute between two regions. This difference can occur in cells, tissues, organs, or even solutions outside the body. Concentration Gradient Principle The concentration gradient is based on the principle of diffusion. Diffusion is the natural …
Scientifically speaking, a fluid is a substance capable of flowing and deforms when exposed to significant force, taking shape with its surroundings. Fluid molecules are sparsely populated particles in constant random motion as they collide with surrounding surfaces and each other. In contrast, solid molecules are laid in regular patterns and are tightly packed, leaving …
Motion is part and parcel of our daily life. A person walking along a straight path, a bird flying in the air, an airplane flying in the sky, a truck moving along a straight road, and water flowing in a river are examples of motion that we encounter daily. There are different types of motion …
Bernoulli’s principle describes a behavior seen in fluids such as liquids or gasses. It predicts that pressure inside a fluid tends to reduce simultaneously when the speed flow of the fluid is high. The reverse also applies, namely that pressure increases when the speed flow lowers. However, this is the opposite of what you may …
When you take a photo with your android phone, laptop, or tablet, you add information to the internal storage system in your electronic device. You add written information to your computer by typing on your keyboard, drawing on your screen, or using a scanner. The camera, keyboard, or scanner helps you provide information and control …
All objects have potential energy stored within them. The amount of potential energy in an object depends on its position in relation to other objects. A trolley at rest has some potential energy caused by its weight. When you push the trolley, you exert force on it, making it move. The moving trolley now has …
QUICK DEFINATION: Weak nuclear forces are fundamental forces in particle physics responsible for certain types of radioactive decay and interactions between particles. They facilitate processes like beta decay and neutrino absorption, mediating interactions within atomic nuclei involving neutrinos and leptons. BRIEF EXPLANATION: Atoms comprise subatomic particles such as protons, electrons, neutrons, neutrino, and muon. Electrons, …
QUICK DEFINITION: Net force is the overall force acting on an object, determined by combining all individual forces acting upon it. It influences the object’s motion, direction, and acceleration, reflecting the sum of all applied forces. EXPLANATION: An object at rest or in motion has different forces acting on it. A book on a table …
Kinetic energy sounds like a complex concept. However, it is actually quite simple. In fact, we encounter kinetic energy every day. In order to understand kinetic energy, you must first understand what energy is. Energy is the force that an object applies. It is the ability or capacity to do work. There are different forms …
