Working out at about 60% to 75% of your maximum heart rate (the so-called fat-burning zone) burns fewer calories than working out at 75% to 85% of your maximum heart rate (the so-called aerobic or cardio zone).
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.
Circular motion. In physics, circular motion is a movement of an object along the circumference of a circle or rotation along a circular path. It can be uniform, with constant angular rate of rotation and constant speed, or non-uniform with a changing rate of rotation. The rotation around a fixed axis of a
