Heart rate: Normally heart rate responds to exercise or physiologic demand levels. Usually we don't see it go over 180-200 even with high levels of exercise. This level while tolerated by 'normals' may be dangerous in patients with heart disease or other forms of disease. In other words, one number doesn't fit all.
In physics, motion is a change in position of an object with respect to time. Motion is typically described in terms of displacement, distance (scalar), velocity, acceleration, time and speed. Motion of a body is observed by attaching a frame of r...
Definition of Relative Motion. Relative motion is the calculation of the motion of an object with regard to some other moving object. Thus, the motion is not calculated with reference to the earth, but is the velocity of the object in reference to the other moving object as if it were in a static state.
