Vertical Projectiles vs. Horizontal Projectiles – a detailed comparison

In this post, we will make a comparison between Vertical projectiles and Horizontal projectiles. When an object is thrown or projected, into the air it’s named a projectile. Essentially, such a projectile (rock, football, bullet, golf ball, or whatever) could be directed straight upward as a vertical projection, directed straight out as a horizontal projection, […]

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 […]

Average velocity – definition, formula, numerical problem

How fast an object is moving can be expressed by the rate at which the position of the object changes with time. For each position xi, we assign a particular time ti. If the details of the motion at each instant are not important, the rate is usually expressed as the average velocity v. Average […]

Velocity time graph – comprehensive Guide

The velocity-time graph is defined as a graphical representation of the velocity of a body in motion with respect to time. Generally, velocity is assigned to the y-axis, and time is pointed on the x-axis. This graph type is also written as a v-t graph or velocity-time graph. The diagram below depicts a few velocity-time […]

Contact Forces between blocks – Application of Newton’s laws

Application of newton’s laws: Newton’s laws of motion give us concepts of force (first law), measurement of force with its equation (second law), and the reaction of force (3rd law). Today we will discuss an interesting topic of mechanics – the application of Newton’s laws. It will cover a few interesting applications of Newton’s Laws […]

Projectile motion – Derivation of Projectile motion equations for class 11 | Maximum height, flight time, Horizontal Range

We will discuss how to derive Projectile Motion Equations or formula and find out how the motion path or trajectory looks like a parabola under the influence of both horizontal and vertical components of the projectile velocity. We will also find out how to find out the maximum height, time to reach the maximum height, the total time of flight, horizontal range, & maximum horizontal range traversed by a projectile.
how to find out the maximum height, time to reach the maximum height, the total time of flight, horizontal range, & maximum horizontal range

Momentum – Definition, Meaning, and Formula

In this post, we will cover the definition and formula of Momentum (Linear Momentum). We will also discuss what it actually means in physics. Momentum Definition | Linear Momentum By Momentum, we mean inertia in motion. More specifically, Linear Momentum or Momentum is defined as the product of the mass and velocity of an object. […]

What is the difference between Instantaneous Speed and Instantaneous Velocity?

What is the difference between instantaneous speed and instantaneous velocity? The instantaneous velocity is the ratio of displacement and the time duration provided the time duration is very small (Infinitesimal with time duration approaching zero).Instantaneous speed is the magnitude of instantaneous velocity and so can never be negative. Instantaneous speed measures how fast a particle […]

Pushing a car, Newton’s 3rd Law and Friction

Hope you have seen people pushing their car when it’s not starting due to some issue. When someone is pushing a car or something like that, he first pushes the ground or floor obliquely backwards with his feet. Following the ‘3rd law of Newton‘ the ground also exerts an equal and opposite force obliquely on […]

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
