What is weight?
The force exerted on an item by gravity is known as the weight of the thing in science and engineering. The gravitational** force** exerted on the item is referred to as weight in several common textbooks. Some people refer to weight as a scalar quantity that measures the gravitational force's strength. Others describe it as the strength of the force applied to a body by systems that work to counteract the effects of gravity. For example, a spring scale measures weight. As a result, the weight would be zero during free fall. When considering air resistance , terrestrial objects might have no weight .
Given,
**Weight **of dog on earth = 80 1/2 pound
Then,
Weight of dog on mars = 5 2 . 80 2 1
= 2 161 . 5 2
= 5 161 = 32 5 1
Hence, the weight of the dog on mars is 32 1/5 pounds.
