Now does gravity effect objects?
Gravity makes objects heavier by increasing or decreasing your weight Gravity does not effect your mass, but does effect how high you can jump.
How do you work out the weight of an object?
Multiply the mass by ten.
How do find out the mass of an object?
Divide the weight by ten.
Why is gravity different on other planets?
Gravity is different on other planets because their mass is different. This affects how much objects weigh. This is why on the moon you experience weightlessness.
