Not understanding the physics of moving particle?

[AndreeU17]

I don't understand how to apply a moving ball? I've kept reading an most people apply physics, the phytagorean theorem and as we'll as sine, cosine & tangent! But I don't understand why we need to use that? How can I get a smooth animation ball that moves to whatever position in the window?

Could someone link me or show me reference or how mathematically it works? I can do the coding on my own

Thanks

Depends on what movement you want to have? A linear movement from A to B? Then just move your ball with the move function.
If you want to move the ball where your mouse is, if you click, you need to get the correct vector first (with very simple math (B - A) and then normalize it, so you always move with the same speed.

Maybe you can specify more on what you need exactly?

I want movement in a linear way in any direction, from 1 point to the other, etc. I'm recreating my own version of Pong & I figured out how to get the ball
Moving already but my problem
Now is getting it to collide with a paddle and bounce back

If you are applying a constant velocity (or moving the ball every update), invert the axis that it bounces off of.

Hits a wall on the left, inverts x to go right, gets the ceiling, inverts y to go down and so on...

For detecting collision, there is a collision class, just google it up
