On Earth all bodies have a weight, or downward force of gravity, proportional to their mass, which Earthâs mass exerts on them. Gravity is measured by the acceleration that it gives to freely falling objects. At Earthâs surface the acceleration of gravity is about 9.8 metres (32 feet) per second per second. Thus, for every second an object is in free fall, its speed increases by about 9.8 metres per second. At the surface of the Moon the acceleration of a freely falling body is about 1.6 metres per second per second.
Physicians and physiologists have warmed to the idea of water walking as therapy and good exercise for people with joint pain and damage for its many benefits, which include: 1  Waterâs buoyancy reduces the impact on joints.  Working out in water can help improve cardiovascular fitness, balance and range of motion.
Each 2,000-2,500 steps is about a mile. Walking a mile burns about 80 calories for a 150-pound person. Depending on your weight, walking 10,000 steps burns between 250 and 600 calories. Most weight loss programs recommend burning 200-300 calories per day in moderate to vigorous exercise. If you walk 10,000 steps per day with 3000 of those steps at a brisk walking to jogging pace, you should be burning enough calories.
