In summary, the conversation is about someone needing to refresh their knowledge on the basics of vectors and finding resources to help with that. They specifically mention intermediate vectors and how it is driving them mad not remembering it. They ask for any resources that can help and mention that they have found a helpful website on vector basics. They also mention that they will deal with projectiles later.

I am doing vectors again and need to remember the bare basics. It also includes vector forces and projectiles (but projectiles can wait for a bit).

For some ridiculous reason, I don't seem to remember this one little bit (ie. intermediate vectors) and it's driving me mad! So I believe I must go back to the basics.

I am asking if someone, anyone, has some resources I can use and follow through it, reminding myself of the basics of vectors; then hopefully, what I'm doing now should be far better as it should be.
Anything shall do.

Yes, it quite is! Thankou so much!

What about projectiles?
 

FAQ: Vectors: Reminder of Bare Basics & Vector Forces

What is a vector?

A vector is a mathematical quantity that has both magnitude (size) and direction. It is commonly represented by an arrow, where the length of the arrow represents the magnitude and the direction of the arrow represents the direction.

What are the different types of vectors?

There are two main types of vectors: displacement vectors and force vectors. Displacement vectors represent a change in position and are commonly used in physics and engineering. Force vectors represent a push or pull on an object and are essential in understanding the motion of objects.

How do you add or subtract vectors?

To add or subtract vectors, you can use the graphical method or the component method. In the graphical method, you draw the vectors to scale and place them head-to-tail to find the resultant vector. In the component method, you break down the vectors into their horizontal and vertical components and then add or subtract them separately.

How do you calculate the magnitude and direction of a vector?

The magnitude of a vector can be calculated using the Pythagorean theorem, where the magnitude is the square root of the sum of the squares of the horizontal and vertical components. The direction of a vector can be calculated using trigonometric functions, such as tangent or sine.

How are vectors used in real life?

Vectors are used in many areas of science and technology, such as physics, engineering, and navigation. They are used to represent forces, velocities, and accelerations, and are essential in understanding the motion of objects. They are also used in fields such as computer graphics and video games to simulate realistic movements and animations.
