Mechanical Energy and its Origin
Mechanical energy is found everywhere in the world and around us. Any object or a thing that moves or doesn’t move consists of some of the other forms of mechanical energy in it. The mechanical energy comes from the position as well as the speed of the moving object. The two energies, that is, kinetic…

Conversion of Energy
The energy can never be created or destroyed, rather converted and transferred. Any kind of energy that is transferred if it causes an object or thing to move is an example of the conversion of energy. Below are some of the examples of how various kinds of energy are converted into mechanical energy: On the…

Potential Energy
The stored energy that the body has when it is not in motion is defined as potential energy. The types of potential energy can be classified into gravitational potential energy and elastic potential energy. e.g: A ball resting in its position. The four kinds of kinetic energy include:

Kinetic Energy and Potential Energy
The energy that a body possesses when it is in motion is defined as kinetic energy, Irrespective of the direction of the motion (horizontal or vertical). The types of kinetic energy can be classified into vibrational kinetic energy, rotational kinetic energy, and translational kinetic energy based on its movement. e.g: Any object falling from a…

Introduction
Mechanical energy refers to the total of kinetic energy and potential energy possessed by an object that is used to do a particular work. In other words, it describes the energy of an object because of its motion or position, or both. If K E and P E refers to the kinetic and potential energies…

Definitions & Solved Example Questions
Intensity is a measure of the energy transmitted by a wave. It is the quantity of energy the wave –conveys per unit time over unit area. It is generally measured with units of watts per square metre (i.e., Wm–2). Intensity will depend on the strength and amplitude of a wave. Intensity is represented by I�…

Determining Deceleration Using Speed Difference and Distance
Convert the initial and final speeds to units that will be useful for calculating the Acceleration (meters per second). Next, square the initial and final speeds. Subtract these squares obtained in the previous step as: square of the final speed minus the square of the initial speed. Divide by two times the distance. This is…

Determining Deceleration Using Speed Difference and Time
This is quite simple. First subtract the ending speed from the starting speed. Convert the speed difference to units of speed that are compatible with the Acceleration to be calculated, usually metre per second. If the speed is in miles per hour, convert that speed to metres per second by multiplying kilometers per hour by…

Deceleration Formulas with Solved Examples
Deceleration is a very commonly occurring phenomenon in our daily lives. Anytime we are travelling, we may notice in the vehicle that when we feel moving forward relative to the vehicle, then we are experiencing Deceleration (a slow down of our Velocity). Here, Deceleration is to be considered as a special case of Acceleration whereby…

What Exactly is a Wave?
In a moving medium, a wave is a type of disturbance. Ocean waves flow across a medium, and we can witness their movement from one place to the next. The motion of an object can be described in terms of speed, which describes the item’s velocity. When a source vibrates and disrupts a particle in…
