Spring scale and masses on Earth, Moon and Mars



Description: Interactive free flash animation to measure yourself the gravitation on the Moon and on Mars.
Is there a relationship between the mass of an object and its weight? The mass is invariable but the weight depends on the location. We are going to measure the weight of an object whose mass we know. Next, we will calculate the quotient of the weight in newtons to the mass in kilograms.

At the place where the measurement is made, the constant of proportionality between mass and weight is in newtons per kilogram.

Definition: We call this gravitational intensity. This is also called gravitational field strength.
