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.
Linear motion (also called rectilinear motion) is a motion along a straight line, and can therefore be described mathematically using only one spatial dimension.he motion of a particle (a point-like object) along a line can be described by its position, which varies with (time).
