What is the resultant force acting on a free falling object?
Gravity.
1 of 12
What do we call force of gravity?
Weight.
2 of 12
What is the acceleration of falling objects called?
The acceleration due to gravity.
3 of 12
What is the equation of falling objects?
W = m x g
4 of 12
What does 'W' stand for? Units?
The Weight in Newtons
5 of 12
What does the 'm' stand for?Units?
Mass in Kilograms
6 of 12
What does the 'g' stand for? Units?
Acceleration due to gravity in metres per second squared.
7 of 12
if a object is not falling what is g?
The gravitational feild strength and its units are newtons per kilogram, N/kg.
8 of 12
What happens when an object falls through a liquid?
The fluid exterts a drag force resisting its motion.
9 of 12
What happens to the drag force as the object falls faster?
It becomes bigger until they are equal to the weight of the object.
10 of 12
What happens when the drag force and weight are equal?
The object stops accelerating and moves at a constant speed.
11 of 12
What is terminal velocity?
The velocity reached by an object when the drag force on it is equal and opposite to the force making it move.
