Any variation from moving at a constant speed in a straight line is described as acceleration.It is very important to realize that going faster, going slower, and/or changing direction are all different kinds of acceleration (changing velocities). Acceleration, a, is defined as the rate of change of velocity with time.If the acceleration is constant over […]
Let’s see how uniform acceleration is different from non-uniform acceleration. Acceleration is defined as the rate of change of velocity. We call an acceleration uniform when the change of velocity per unit time is constant i.e. velocity changes by an equal amount in an equal interval of time. In uniform accelerated motion velocity-time graph is […]
The quantity that tells us the rate at which an object is changing its velocity at a specific instant in time anywhere along its path is the instantaneous acceleration. That means when we say ‘acceleration’ of a body we actually mean instantaneous acceleration. Another related term is the average acceleration that is basically for a […]
In this post, we have taken the Average Acceleration Formula as our topic of discussion. We will see how to define and find it, and how to solve sample numerical problems using the formula. This post is useful for class 11 students who are studying this chapter. When velocity changes an object is said to […]
A stone falls towards the earth – why? A stone falls back on the ground. But the earth doesn’t seem to move towards it. Why? As said by this law of universal gravitation every object in this universe is attracting every other object towards it. This force of gravitational attraction between any two objects in […]
In this post, we will find out (a) how to find the weight of a freely falling body (b) How the velocity of a freely falling body changes every second if we ignore air drag force (air resistance)? (c) Why do we feel weightless during freefall (d) Kinetic energy of a body under free fall (e) Applicability of Law of conservation of energy for free fall (e) how distance traveled per second varies
In this post, we will discuss the fundamentals of Force in physics which will include the definition of force and force formula, types and examples of force, reference to Newton’s laws of motion, and units of force. What is a force? Force is a push or a pull that causes a change of velocity of […]
