Define weight as the gravitational pull of the Earth.
When you drop an object, it falls because the Earth pulls it downwards. This force with which the Earth pulls an object towards itself is called the weight of the object.
The weight measures how strongly an object is pulled by gravity.
Explain how a spring balance works.
A spring balance is a simple device used to measure weight (force). It consists of a spring fixed at the top end and a hook attached at the bottom.
When you hang an object from the hook, gravity pulls the object down. This downward pull stretches the spring.
Fill in the blank to test mass vs weight differences.
is the amount of matter in an object and is measured in kilograms. On the other hand, is a gravitational force and is measured in . Because gravitational pull varies by location, an object's weight can change. For example, if you travel to Jupiter, your mass remains the , but your weight will because Jupiter pulls harder than Earth.
