The document defines weight as the force of gravity acting on an object. It provides the formula for calculating weight (W) as mass (m) multiplied by the acceleration due to gravity (g). On Earth, g equals 9.81 m/s2, but it is 1.6 m/s2 on the moon. Using the formula and values given, the document calculates the weight of a 100kg object on Earth as 981N and prompts the reader to calculate its weight if located on the moon instead.
2. Definition The force of gravity acting on an object W = mg Where: W = weight(measured in newtons) m = mass (measured in kg) g = acceleration due to gravity On earth, this is 9.81 m/s/s
3. W=mg We need to find W We are given m = 100 kg We know g is always 9.81 m/s/s on earth W = (100)(9.81) This equals 981N
4. On the moon What if that same object is on the moon? Acceleration due to gravity on the moon is: 1.6 m/s/s Therefore, you would replace the 9.81 m/s/s with 1.6 m/s/s What answer do you get?
