The term “motion of a body” refers to the shift in a body’s position over a period of time. Some examples of objects exhibiting motion… Read More
A distance-time graph is a graphical representation of how far a body has traveled in a specified amount of time. It is used to depict… Read More
An object performing a circular motion is changing its velocity every second. That means a force acts on the particle which makes it move in… Read More
Force is a push or a pull that changes or tends to induce a change in the state of the object or it may modify… Read More
Acceleration is defined as the rate of change in velocity. This implies that if an object’s velocity is increasing or decreasing, then the object is… Read More
Newton’s third law is one of the basic laws of physics which is very useful in various aspects. It states that if body A exerts a… Read More
Power in Physics is defined as the time rate of the amount of energy converted or transferred. In the SI system (or International System of… Read More
Newton’s Laws of motion were first proposed by Sir Issac Newton in the late 17th century. Newton’s First Law of Motion basically states that a… Read More
Acceleration due to gravity (or acceleration of gravity) or gravity acceleration is the acceleration caused by the gravitational force of attraction of large bodies. As… Read More
Potential energy in physics is the energy that an object possesses as a result of its position. The term Potential Energy was first introduced by… Read More
Kinetic Energy is the energy associated with an object moving with a velocity. For an object of mass m and velocity, its kinetic energy is… Read More
