Hi I was reading a physics book and i came to the part where the started to explain vectors and scalars and i got really confuzzled(confused/puzzled) please help
Aartt said:thanks :D for all the explanations i got the basics but the thing on the bottom of deltas post was O_O confusing but oh well a 6th grader wouldn't understand it.
Delta² said:Yes just forget those at last paragraph i said more than i should and don't make sense if i don't explain some other things first like what is vector addition and functions of time.
Aartt said:what is AP?

Phrak said:I don't know what a scalar is. Is there a common definition or does it change with context.
Is it constant over general coordinate transformations?
Is a pseudo scalar a scalar?
Is a function a scalar?
A vector is a quantity that has both magnitude and direction, while a scalar is a quantity that only has magnitude. In other words, a vector describes both the size and direction of something, while a scalar only describes its size.
Vectors are typically represented using arrows, where the length of the arrow represents the magnitude and the direction of the arrow represents the direction. Scalars are typically represented using a number or a point on a number line.
Vectors can be added or subtracted by combining their magnitudes and directions using the rules of vector addition and subtraction. Scalars can also be added or subtracted using basic arithmetic operations.
Vectors can be seen in everyday life in examples such as displacement, velocity, and force. Scalars can be seen in examples such as temperature, mass, and time.
In physics, vectors are used to describe the physical quantities that have both magnitude and direction, while scalars are used to describe the physical quantities that only have magnitude. Vectors are often used to represent forces, velocities, and accelerations, while scalars are used to represent energy, mass, and time.
