A force vector - or just about any physical vector, for that matter - is usually represented as an arrow. The direction of the arrow represents the direction of the vector; the length of the arrow is supposed to be proportional to the force (or to whatever physical quantity you are representing).
A vector diagram will show the direction of the force as well as its magnitude
Force vectors are represented by arrows in a force diagram.
They usually are.
simply: No, Velocity vectors are different to force vectors. One measures velocity and one measures force so you can not simply add/subtract/multiply/divide them together and get something meaningful.
They aren't, but they can be described as vectors. The most common way is to describe them as vectors of three components in Euclidian space.
A law which states that if a body is acted upon by two vectors represented by two sides of a triangle taken in order, the resultant vector is represented by the third side of the triangle.
Force vectors are represented by arrows in a force diagram.
E=mc^2 to the negative 100. bottomline is force vectors are free body diagrams always sometimes
Yes. This is the basis of cartesian vector notation. With cartesian coordinates, vectors in 2D are represented by two vectors, those in 3D are represented by three. Vectors are generally represented by three vectors, but even if the vector was not in an axial plane, it would be possible to represent the vector as the sum of two vectors at right angles to eachother.
They usually are.
Muscle force is the force produced by the contraction of a muscle. Force vectors, torque vectors, and difference vectors can all be used to help describe this force.
No
If two vectors are represented by the same magnitude and direction they are said to be equal.
simply: No, Velocity vectors are different to force vectors. One measures velocity and one measures force so you can not simply add/subtract/multiply/divide them together and get something meaningful.
Systemic Arteries are represented as red in diagrams because they have oxygen in the blood, whereas Pulmonary Arteries are represented as blue because they carry deoxygenated blood.
They aren't, but they can be described as vectors. The most common way is to describe them as vectors of three components in Euclidian space.
A law which states that if a body is acted upon by two vectors represented by two sides of a triangle taken in order, the resultant vector is represented by the third side of the triangle.
If the two vectors are directly opposite each other, then subtract the smaller one from the larger one and that will be your resultant force. For example, if the force downwards is 5 N and the force upwards is 2 N, the resultant force is 3 N downwards. If the one or both of the two vectors are angled, you need to replace the angled vectors with two right-angled vectors and then add those to create the resultant vectors.
