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...
Motion can be defined as a change in the position of a body with respect to time and another body. Motion is relative in physics. Motion and rest are fundamental ideas in physics. There is no absolute rest as all bodies in the Universe are in a perpetual state of motion. Stars, planets, constellations and even galaxies are in motion with respect to each other.Planets revolve around stars and galaxies move away from each other.
