Projectile Motion:

What is projectile motion? When a particle is projected at certain angle. Suppose this is x and this is y, and we have thrown a ball like this from here, we have thrown it u initial speed at theta angle, so this object will perform this motion. Yes or no? This is called projectile […]

So we were dealing with this particular question that the ball is projected vertically upward with some velocity and we are looking forward to find or to calculate distance or displacement covered in last t seconds. What is the meaning of last t seconds? Last t seconds of upward journey, this is what we have […]

So, students, in last lecture we were dealing about linear motion with constant accelerations and we were having some problems or some practice questions on that concept. Let’s take few more examples on the same idea of linear motion with constant acceleration.
Let’s consider a problem, an air balloon is moving vertically upward with constant speed […]

A particle moving with constant acceleration, moving with constant acceleration of 4 meters per second square covers 60 meters distance in 8th second of its motion. Find the initial velocity of the particle?

This is totally fine.

Displacement in 8th second will be initial speed plus acceleration by 2, 2 into 8 minus 1. Yes or no? […]
