Forces, Newton`s Second Law
... This means that the weight W of body has the same magnitude as gravitational force acting on it. However, this statement is only true in inertial reference frame. If you try to perform weighting of the body in the elevator moving with some nonzero acceleration, you can come up with some very strange ...

Work
... The work, W, done on a system by an agent exerting a constant force on the system is the product of the magnitude F of the force, the magnitude Dr of the displacement of the point of application of the force, and cos q, where q is the angle between the force and the displacement vectors. The m e a ...

Vectors: A Geometric Approach
... One application of vectors that is related to the concept of force is work. Intuitively, work is a measure of the “effort” expended when moving an object by applying a force to it. For example, if you have ever had to push a stalled automobile or lift a heavy object, then you have experienced work. ...

... We say that the basic vectors i, j, and k form a basis for R3 in that any vector a, b, c can be written as a, b, c = ai + bj + ck Conversely, we say that ai + bj + ck is a linear combination of i, j, and k. EXAMPLE 5 Convert the vector v = 2i + 3j − k to component form, and then sketch the vecto ...
