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.
Torque is a force which causes the rotation of an object. Linear motion is the most basic of all motions. Linear motion is the type of motion in which all parts of an object move in the same direction and each part moves an equal distance. Linear motion is measured by speed and direction.
