field strength at the point where the object is: weight = mass × gravitational field strength [W = m g ] weight, W, in newtons, N mass, m, in kilograms, kg gravitational field strength, g, in newtons per kilogram, N/kg The weight of an object and the mass of an object are directly proportional. Weight is measured using a calibrated spring balance (a newtonmeter). Define weight and mass and explain the difference between them. Calculate the weight of an object on using W = mg. Rearrange this equation to find any unknown quantity. Give the correct units of weight and mass. Convert quantities into SI units (eg grams into kilograms). Compare the weight of an object on different planets when given the gravitational field strength of the planets. Describe the relationship between weight and mass and what would happen to weight if mass was doubled. Would aliens living on a massive planet be smaller than animals on Earth? How can a spring be used to find the weight of an object on Earth? WS 1.2, MS 3b, 3c Recall and apply this equation. In any calculation the value of the gravitational field strength (g) will be given. Research how the pull of gravity varies around the Earth and how this would affect the weight of a 1 kg mass. To achieve this, students can make a model of what a 1 kg mass would weigh on different planets using tin cans filled with sand to represent the planets in our Solar System. Investigate how a spring stretches with weight. Plot a graph of the results and then using this and the extension of the spring find the weight of small objects in the lab or lumps of wood with hooks attached.
