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.
Regents Physics - Defining Motion. An object's position refers to its location at any given point in time. If we confine our study to motion in one dimension, we can define how far an object travels from its initial position as its distance, d.. Distance, as defined by physics, is a scalar. It has a magnitude, or size, only.
