Acceleration

Acceleration

What is Acceleration? Any variation from moving at a constant speed in a straight line is described as an 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 […]

How uniform acceleration is different from nonuniform acceleration?

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 […]

Average Acceleration and its formula & solved numerical problems

When velocity changes an object is said to undergo acceleration. Quantitatively, we define acceleration as the rate of change of velocity, just as we defined velocity as the rate of change of position. The average acceleration over a time interval Δt is the ratio of change in velocity Δv (that takes place over the time […]

Freefall in physics

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

Force in Physics

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 […]
