The magnitude of the resultant force is the length of the vector representing the force, which can be calculated using the Pythagorean theorem. The coordinate direction angles refer to the angles that the resultant force vector makes with the x, y, and z axes.
The magnitude of the resultant force can be found using the Pythagorean theorem, which states that the square of the hypotenuse (in this case, the resultant force) is equal to the sum of the squares of the other two sides (the x and y components of the force).
No, the magnitude of a vector cannot be negative. It represents the size or length of the vector and is always a positive value.
The coordinate direction angles provide information about the direction of the resultant force vector in relation to the axes. They can be used to determine the orientation of the vector in three-dimensional space.
The coordinate direction angles can be calculated using trigonometric functions, such as sine, cosine, and tangent. The angle between the resultant force vector and each axis can be found by taking the inverse of these functions using the x, y, and z components of the force.
