Gravitational Force Through Real-World Examples

According to Newton's law of gravitation, every object in the universe attracts every another object, then why dont objects move under the influence of this force of gravitation?

Why is the value of g greater at the pole?

The faster an object moves, the ________ is its kinetic energy.

What do you mean by free fall?

Why are objects weightless, when they are in free fall ?

Why does air have pressure?

Is this a true statement: If an object is weightless, then no gravity is acting upon it?

How are mass and weight related?

What would increase the force of gravity between two objects?

What are surface waves ?

(a) x/4
(b) x/2
(c) 2x
(d) 4x
