If an object is just let fall from a height, what is the initial velocity (u)?
0
What is the measure of inertia of an object?
Mass
What does the weight of an object depend on?
Both mass and acceleration due to gravity
What happens to the final velocity of an object projected vertically upward at its maximum height?

What is the universal law of gravitation?
The force between two objects is inversely proportional to the product of their masses and directly proportional to the square of the distance between them.
What is the SI unit of the universal constant G?
