Projectile Motion Formula, Equations, Derivation for class 11

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.

Terminal Velocity, Free Fall, & Drag force

By Anupam M

Here we will discuss in detail the terminal velocity and Terminal Velocity Equation. Before that, we will also cover a few important pointers on free fall and then discuss Air Drag or Air resistance, Drag force, and Drag Force Equation. In one of the earlier posts, we have discussed the free-fall equations. You can check that if […]

Angular Motion & Linear Motion Quantities – derivation of 3 relations

By Anupam M

In this post, we will focus on the definitions of circular motion and linear motion first which will show their basic differences as well. In addition to this, we’ll derive a couple of important relationships between the quantities of circular motion and linear motion. We will derive the following:a) Relationship between angular displacement and linear displacementb) […]

What is the difference between Instantaneous Speed and Instantaneous Velocity?

By Anupam M

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 […]

Vertical motion when a ball is thrown vertically upward with derivation of equations

By Anupam M

when a ball is thrown vertically upwards it goes up for a while and then stops and starts to come down and touches the ground. Maximum height reached, velocity at the highest point, time for upward and downward movements, velocity before touching the ground- find all these mathematically

Freefall in physics

By Anupam M

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
