Velocity and Acceleration We know that velocity in physics is the rate of change of position with time and acceleration is defined as the rate of change of velocity with time. There are formulas that can be used to calculate…
Mass and weight are terms we use frequently and interchangeably. However, have you ever thought over the fact why an object weighs less on the Moon than on Earth? You would be able to answer this question if you understood…
This article contains a list of the center of mass formulas along with some centre of mass problems and examples. Centre of mass formula list The motion of the Center of mass examples A few examples of motion of the…
In physics, distance and displacement are two fundamental quantities used to describe motion in physics. This quiz tests your understanding of both concepts through 15 worked questions, each with a detailed step-by-step solution. Try to answer each question yourself before…
The concept of work done is fundamental in physics. Whether you are studying physics as a pastime or preparing for tests such as the MCAT, AP Physics, GCSE, or IB, you must track your progress. You can test your concepts…
We already know what is speed in physics. In this article, we will learn about instantaneous speed. We would also look at a few example questions based on instantaneous speed. Speed DefinitionSpeed is defined as the rate at which the…
What is the effect of reducing friction on a machine? will be discussed in this article. Before proceeding, let us first examine the concept of friction or frictional force. What is friction? Friction is described as a force that tends…
Examples of zero work done this is what we would discuss in this article. We use phrases like the overworked and hard worker to express a person’s effort. But that is not how we define work done in physics. Work…
