What happens to weight when you go to the moon?

Back

Your weight decreases on the moon because the moon's gravity is weaker than Earth's.

Front

What is the formula to calculate weight?

Back

Weight (W) = mass (m) × gravity (g). On Earth, g is approximately 9.8 m/s².

Front

Can weight change?

Back

Yes, weight can change depending on the gravitational force acting on an object.

Front

What is a spring scale?

Back

A spring scale is a device used to measure weight by the amount a spring stretches under the load.

Front

What is the relationship between weight and gravity?

Back

Weight is directly proportional to the strength of the gravitational force acting on an object.
