This guide explores the concept of weight variation due to gravity differences between Earth and the Moon. It discusses how an object weighing 1 lb on Earth will weigh approximately 0.17 lb on the Moon, leading to calculations for various weights, including 4 lb and 7 lb dumbbells. Through example scenarios, we will understand the effects of lunar gravity on objects and provide formulas for calculating weight in different gravitational fields. This insight enhances our comprehension of space physics and helps with practical applications in astronomy and physics.

Example 1: Science Application Something that weighs 1 lb on Earth weighs 0.17 lb on the Moon. How much would a 4 lb dumbbell weigh on the Moon? Ex. 2 What if the dumbbell weighed 7 lb?
Ex. 3 0.07 0.8 Ex. 4 1.34 2.5
Ex. 5 Evaluate 5x for x = 3.062 Ex. 6 Evaluate 5x for x= 4.79
