Acceleration and Weight
Newton's second law of motion explains the weight of objects. Weight is a measure of the force of gravity pulling on an object
of a given mass. It's the force (F) in the acceleration equation (a=F/m). This equation can also be written as: F=mxa
The acceleration due to gravity of an object equals 9.8 m/s2, so if you know the mass of an object, you can calculate its weight as.
F-m x 9.8 m/s2 As this equation shows, weight is directly related to mass. As an object's mass increases, so does its weight For
example, if mass doubles, weight doubles as well.
1. Define weight
2 How is the weight of an object related to its mass?
3. If an object has a mass of 50 kg, what is its weight?
