Question

hello I want to ask than in angular projection topic of 11th class.
how Ux= ucos theta
Uy = usin theta​


please give detailed information and possibly in video.
​

Answer 1

Answer:

Sorry But here Video facility is not available.

Explanation:

Let us solve Practically.

To see about Projectile Motion topic regarding Ux and Uy

For example:

When a object (ex) man moves normally in a plane surface without any inclination θ then in order to find his Initial velocity we can use Newton's three laws of motion

But similarly what would happen when object (like ball ) projected with velocity U with angle theta θ ??

Yes in that case we should take it's axis (i.e) x and y axis in order to trace the path of ball moving and for our convenience to solve the problem.

So when we take it's components (i.e)  x and y axis we will get x axis along right side and y axis along upside as everyone knows.

As the object is project at some angle θ it's initial velocity is given by (u) as mention in attached diagram.

So as we previously told that right side is x axis and upside is y axis,

Velocity along x direction must be taken as Ux = Ucosθ and along y direction must taken as Uy = Usinθ

This is applicable to all projectile problems.

This is way to solve projectile problems.

In order to solve projectile problems we must good at components and directions.

Hope you Understood.
