Difference between Speed and Velocity # Speed Velocity 1. Speed is a scalar quantity. Velocity is a vector quantity. 2. It only describes the magnitude of motion. It is measured in units of distance per unit of time (e.g., meters per second). 3. It is always positive or zero. It can be positive, negative, or …
Fundamental quantities in physics are physical quantities that cannot be defined in terms of other quantities. They are the building blocks of all other physical quantities, and they form the basis of the International System of Units (SI). The seven fundamental quantities in SI are: Fundamental Quantities as “Base Units” These fundamental quantities are considered …
A positive force in physics is a force that moves an object in the direction that we want it to go, or towards a desired outcome. Positive forces can be applied in various ways such as pushing, pulling, or using some other method to create a force in the intended direction. Having a good understanding …
In the context of physics, resilience denotes the capacity of a material or system to withstand stress, deformation or damage, while still retaining its structural integrity and ability to function as intended. This means that a physical entity that is resilient can withstand external forces and bounce back to its original state or level of …
Dielectric materials are basically insulators, which means that no current flows through them when a voltage is applied. However, certain changes do occur in the material at the atomic level as dielectric material becomes polarised when a voltage is applied across it.Polarisation is an effect that slightly shifts electrons towards the positive voltage because atoms are …
Electric susceptibility (χe) is a quantitative measure of how much an electric field applied to a dielectric substance generates polarisation.The electric susceptibility is a dimensionless constant When a dielectric is placed in an electric field, it acquires a polarization that depends on the field. The electric susceptibility χe relates the polarization to the electric field.The polarization vector …
Hydrochloric acid (HCL) is a water-based, or aqueous, solution of hydrogen chloride gas. It is also the primary component of gastric acid, an acid generated spontaneously in the human stomach to aid digestion.Furthermore, HCL is also synthesized for a range of industrial and commercial uses, and it may be generated using a variety of production procedures, …
Stress in physics acts as a gauge for the strength of the forces that lead to deformation. Stress is typically described as force per unit area. Tensile stress occurs when forces act on something and make it elongate, like when an elastic band is stretched. Similarly, When an object is compressed by forces, compression stress results. …
Heat can be transferred in three ways: conduction, radiation, and convection.Conduction refers to the transfer of energy via the movement of particles in contact with one another. In technical terms, conduction is the transfer of heat energy through collisions between neighboring atoms or molecules. Conduction occurs more easily in solids and liquids because the particles …
Quarks in physics are the basic building blocks of matter. They are most commonly found inside protons and neutrons, the particles at the heart of every atom in the universe. Quarks appear to be truly fundamental particles based on current experimental evidence; they cannot be further subdivided.A fundamental particle is not made of other particles …
Can displacement be negative: Yes, displacement can be negative as it is a vector quantity that depends upon magnitude and direction. The negative sign signifies only the direction. Negative Displacement Displacement Formula Displacement is defined as a change in an object’s position. The following equation may be used to define it mathematically: Displacement=Δx=x2−x1 Whereas x2 …
Ammonium dihydrogen phosphate (ADP) is the ammonium salt of phosphoric acid (molar ratio 1:1). It is used as a fertilizer. It contains dihydrogen phosphate. It is also known as monoammonium phosphate (MAP). ADP is a key component in agricultural fertilizers as well as several fire extinguishers. It is also used extensively in optics and electronics. Compound Name …
