What is gravity?
The force of attraction between objects is due to their masses.

To calculate weight on any given planet, you would use the formula
weight = mass x gravity
On mars, the force of gravity is 3.7 m/s². The weight of an object is 250 kg. Describe how you would solve for the mass.
mass = 250 kg / 3.7m/s²
As the distance between two objects increases, what happens to the gravitational pull?
Gravitational pull decreases
