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 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.
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.
What is 'g'?
Acceleration due to gravity (gravitational field strength) in m/s².
What happens when an object is in free fall?
The object's acceleration is equal to the acceleration due to gravity (g).
What is the effect of increasing mass on gravitational force?
Increasing mass increases the gravitational force (weight), assuming the gravitational field strength remains constant.
What is the effect of increasing gravitational acceleration on gravitational force?
Increasing gravitational acceleration increases the gravitational force (weight), assuming mass remains constant.
