In physics, many numbers have both magnitude and net direction. These numbers, with magnitude and net direction, are called vectors. A vector’s direction is usually given as an angle relative to the x-axis, or relative to another vector. The magnitude of a vector is just a number.

## What is 1D and 2D kinematics?

1D kinematics can be used when the object is moving either left and right or up and down. 2D kinematics can be used for projectile motion (both left or right and up or down at the same time) With projectile motion, the x and y axes are linked by time (t)

## What is 3d motion in physics?

Motion in three dimension: Motion in space which incorporates all the X, Y and Z axis is called three dimensional motion. Example: Movement of gyroscope is an example of three dimensional motion.

## How do you add vectors A and B?

## How do you subtract vectors in physics?

## What does subtracting two vectors give you?

The vector subtraction of two vectors a and b is represented by a – b and it is nothing but adding the negative of vector b to the vector a. i.e., a – b = a + (-b). Thus, subtraction of vectors involves the addition of vectors and the negative of a vector. The result of vector subtraction is again a vector.

## Is AP Physics 1 or C harder?

We all know that AP® Physics 1 is easier than AP® Physics C. We note that many of the AP® Physics C courses self-select for those motivated students or those with higher grades in Math. That is the reason for the ridiculously high rates for AP® Physics C as compared to AP® Physics 1.
