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.
Motion is not a 'relative term'. Motion is relative. The book that you're reading on the airliner while you fly to the coast is moving at 600 mph relative to â¦ somebody on the ground.
