Conservation of mechanical energy: Formula and Examples
Conservation of mechanical energy is defined as “the total mechanical energy of a system neither increases nor decreases in any process”. A simple example of the conservation of mechanical energy is a rock allowed to fall due to Earth’s gravity…

Difference between Accuracy and Precision
The difference between accuracy and precision is that Accuracy means how close a measured value is to the actual value and Precision means how close the measured values are to each other. Although the two words accuracy and precision can…

Value of Acceleration due to gravity
Acceleration of a freely falling body is called gravitational acceleration or acceleration due to gravity. The value of gravitational acceleration is 10 ms-². Acceleration due to gravity formula is calculated by using Newton’s law of gravitation. Acceleration due to gravity…

Difference between conservative and non conservative force with examples
Conservative forces are those forces for which work is done depending only on the initial and final points, while Non-Conservative forces are those forces for which the work is done or the kinetic energy depends on other factors such as…

Thermal Equilibrium: Definition, Examples
What is Thermal Equilibrium? By contacting two bodies that are at different temperatures, the one that is warmer yields part of its energy to the one with the lowest temperature, to the point where both temperatures are equal. This situation…

What is radiant energy? Is radiant energy potential or kinetic?
Radiant energy is the energy possessed by electromagnetic waves such as visible light, radio waves, ultraviolet (UV), infrared (IR), etc. The main characteristic of this energy is that it propagates in a vacuum without the need for any material support. It is…

Difference Between Uniform and Non Uniform Motion with Examples
The basic difference between uniform and non-uniform motion is that: In uniform motion, a body moves with a constant speed such as the Motion of the earth around the sun. While in non-uniform motion a body moves with a variable…
