Uniform Motion | Uniform Linear Motion

Uniform motion or Uniform Linear Motion means motion with a constant or uniform velocity (constant magnitude and constant direction). As a one-dimensional example of this, the car in Figure 1 has a uniform velocity. – It travels the same distance in the same direction and experiences the same displacement in equal time intervals (50 km […]

Projectile Motion Formula class 11

This post on Projectile Motion Formula for class 11 presents a set of formulas that describe a projectile motion that is parabolic in nature and helps to find out important motion parameters as well. Let’s find out those formulas one by one, along with a brief idea for each formula.

Range of Projectile formula

The range (Horizontal Range) of a projectile is defined as the horizontal distance between the point it touches the ground and the point of projection. Now, let’s find the Range of the Projectile formula.

Projectile Motion Equations

Here, is a list of projectile motion equations. This list includes the equation of projectile motion path, and other important equations like time to reach maximum height, maximum height, horizontal range, max horizontal range, displacement, etc.

What is Free Fall Class 9

What is free fall class 9 – The falling of an object from a height towards the earth under the gravitational force of the earth (with no other forces acting on it) is called free fall. And such an object is called a freely falling body (or ‘freely falling object’). So, whenever a body (or object) falls towards the earth on its own, we say that it is under free fall or that it is a freely falling body (or freely falling object).

Inertia class 9

In this post, we will briefly cover the topic of inertia for class 9 students. We will define, classify, and present examples of each type of inertia. We will also see how mass relates to inertia.

Non-uniform acceleration on a velocity-time graph

If the acceleration is changing, the gradient of the velocity-time graph will also be changing – so you won’t get a straight line. Increasing acceleration is shown by an increasing gradient — like in curve 1 below. Decreasing acceleration is shown by a decreasing gradient – like in curve 2 below. How to find the […]

The velocity-time graph & speed-time graph – comparison

Here, we will find the differences between the velocity-time graph & speed-time graph. As an example, we will compare the velocity-time and the speed-time graphs for a ball being thrown up into the air. Differences between the velocity-time graph & speed-time graph A speed-time graph may have some similarities with a velocity-time graph, but these […]

How to determine Acceleration on displacement-time graphs

In this post, we will see how to determine the acceleration from a displacement-time graph. The gradient of a displacement-time graph shows velocity. Acceleration is the rate of change of velocity, so on a displacement-time graph, acceleration is the rate of change of the gradient. A graph of displacement against time for an accelerating object […]

Displacement-Time Graphs

Displacement-time graphs show an object’s position relative to its starting point over a period of time. They’re useful because they can be used to describe an object’s motion as well as find its velocity at a given point. Plotting displacement-time graphs Let’s see how to plot displacement-time graphs for moving objects.The suvat equations can be […]

The effect of air resistance on projectile motion

In this post, we will find the effect of air resistance on projectile motion. We have seen that in the absence of air resistance, the trajectory or path followed by a projectile is a parabola and that the path depends only on the initial speed and angle of projection. But in the real world, all […]

Motion in 2 and 3 Dimensions – formula & numerical

We will discuss and list down the formulae of position, velocity, and acceleration related to the Motion in two and three Dimensions using unit vectors i, j, and k format. We will list down the 2-Dimensional equivalent of motion equations or suvat equations. Also, we will solve numerical problems using the formulas of the position […]

Horizontal projectiles – formulas with derivation

Horizontal projectiles are directed straight out as a horizontal projection. It undergoes downward acceleration under the influence of gravity and hence gets an increasing downward velocity. At the same time, the horizontal velocity of the horizontal projectile remains the same throughout the flight as there are no forces in the horizontal direction if you ignore […]

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, […]
