IGCSE Grade 7 Science Effect of gravity on objects
|
gravity is the force by which a body pulls another object towards its center.
Earth's pull
Weight = mass X gravitational acceleration and gravitational acceleration is 9.8m/s2 on earth.
force with which earth attracts the object
the gravitational force and the distance between the two objects are inversely proportional.
A body is drawn towards the center of the earth or any other mass-containing physical body by the force of gravity.
different gravity on different planets affects the weight of objects.
Weight is the force of gravity acting on an object.
W = mg
Here, G= acceleration due to gravity, m = mass of object 1, M = mass of object 2 and r = distance between the two objects taken from their centre.
