What is the definition of a gravitational field?
A region around a massive object where other objects experience a force of attraction.
Define mass.
A measure of an object's inertia (how much it resists changes in motion). It's an intrinsic property and doesn't change based on location.
Define weight.
The force of gravity acting on an object. It changes depending on the gravitational field strength.
What is free fall?
When the only force acting on an object is gravity.
Define acceleration due to gravity (g).
The acceleration of an object in free fall, approximately 9.81 m/s² on Earth.
What are the differences between mass and weight?
Mass: Measure of inertia, intrinsic property, measured in kg. | Weight: Force of gravity, depends on gravitational field, measured in N.

What is 'g'?
Acceleration due to gravity (gravitational field strength) in m/s².
