Weight is the force of gravity acting on an object. It is a measure of how heavy an object is.
Mass is the amount of matter in an object, while weight is the force of gravity acting on that mass. Mass is measured in units such as grams or kilograms, while weight is measured in units such as pounds or newtons.
Weight is measured using a balance or a scale. A balance compares the weight of an object to a known standard, while a scale measures the force of gravity acting on the object.
Yes, weight can change if the gravitational force acting on an object changes. For example, an object would weigh less on the moon than it does on Earth because the moon's gravitational pull is weaker.
Weight is typically measured in pounds (lb) in the United States and in kilograms (kg) in most other countries.
