Mass, Weight, and Gravity
The mass of an object, measured in kilograms, tells you now much matter an object is composed of
The weight of an object measured in newtons, is the gravitational force that acts on the object.
Gravity: the force that exists between any two object with mass
Acceleration of free fall: the acceleration of an object falling freely under gravity.
Acceleration due to gravity: the acceleration of an object falling freely under gravity
Gravitational field strength: the gravitational force exerted per unit mass placed at that point
Gravitational field strength = weight: mass
Terminal velocity → the greatest speed reached by
