Answer:An object in free fall falls under gravity alone with no friction
Explanation:
Gravity in physics is explained as that force which pulls us down towards the center of the earth; helps us not to float .
What does friction mean?
Friction is a force that acts in an opposite direction to that of the object's movement .
So if the object is not pushed in an opposite direction by any force it will fall freely , it will fall and roll down or it will fall and continue to move in its direction for example an orange falling from a tree ( pulled by gravity) without any force opposing it's movement it will fall continue sliding or rolling down unless there is something hindering it's movement.
Another example is, if you were running and reach a corner and decided to halt your shoes will act as a friction to help you stop immediately.
However if you run in the rain and the road is slippery or there are puddles on the road, when you want to slow down or stop the friction will be less.
The less friction means the harder it is to halt which also occurs when you drive during rain weather .
It is hard to stop the car in time due to less friction on the tires which is reduced by the slippery wet road .
An object will fall and slide down unless some opposing force is there to oppose that movement , that is what free fall means.
The Enlightenment was a philosophical movement in 18th-century Europe that criticized the sovereign rule of kings and promoted human reason. This movement, along with economic and political unrest within France, caused both the nobility and peasantry to revolt, ending centuries of feudal rule and giving rise to a national assembly. The revolution of 1789 produced turmoil in the years that followed, but it forever changed how the country was governed.
When Napoleon Bonaparte invaded Spain and Portugal in the early 19th century, the colonies established by those countries throughout the Americas worried they might be next. Yet Bonaparte's invasion weakened the imperial authority governing the colonies, giving their inhabitants an opportunity to fight for independence. It took nearly 25 years for all the colonies gain independence and put an end to imperial rule. This success was in large part due to the leadership of Simón Bolívar who, at a young age, was influenced and motivated by the Enlightenment's ideas.
