Which would hit the ground with the most force an elephant jumping off a cliff or a mouse jumping off the same cliff Why?
The elephant clearly has more mass than the feather, yet the amount of gravity (force) is the same for each. The elephant has the greatest acceleration, yet the amount of gravity is the same for each.
What falls faster an elephant or a mouse?
True or False? Free body diagrams of the Elephant and Mouse show that the mouse quickly reaches terminal velocity, (Terminal Velocity occurs when Fg = Fair) while the elephant continues to accelerate for much longer. The elephant is therefore going faster when it hits the water.
Why is potential energy highest at the top?
The amount of gravitational potential energy an object has depends on its height and mass. The heavier the object and the higher it is above the ground, the more gravitational potential energy it holds.
Which will hit the ground first a heavy or light object?
In other words, if two objects are the same size but one is heavier, the heavier one has greater density than the lighter object. Therefore, when both objects are dropped from the same height and at the same time, the heavier object should hit the ground before the lighter one.
Will 2 objects fall same speed?
Free Fall Motion Objects that are said to be undergoing free fall, are not encountering a significant force of air resistance; they are falling under the sole influence of gravity. Under such conditions, all objects will fall with the same rate of acceleration, regardless of their mass.
Do heavier objects fall faster?
Galileo discovered that objects that are more dense, or have more mass, fall at a faster rate than less dense objects, due to this air resistance. Air resistance causes the feather to fall more slowly.
What falls faster a feather or a rock?
Galileo discovered that objects that are more dense, or have more mass, fall at a faster rate than less dense objects, due to this air resistance. A feather and brick dropped together. Air resistance causes the feather to fall more slowly.
Do lighter or heavier objects fall faster?
Answer 2: No, heavier objects fall as fast (or slow) as lighter objects, if we ignore the air friction. The air friction can make a difference, but in a rather complicated way. The gravitational acceleration for all objects is the same.
Do heavier objects fall faster Galileo?
It was in the nature of falling, said Aristotle, that heavy objects seek their natural place faster than light ones — that heavy objects fall faster. Galileo took an interest in rates of fall when he was about 26 years old and a math teacher at the University of Pisa.
What did Galileo experiment prove?
According to the story, Galileo discovered through this experiment that the objects fell with the same acceleration, proving his prediction true, while at the same time disproving Aristotle’s theory of gravity (which states that objects fall at speed proportional to their mass).
Which ball falls faster?
Heaver objects fall faster. If you drop a heavy and light object together, the heavy one will get to the ground first. This is trick question. I remember in physics that everything falls the same.
Who said heavier objects fall faster?
Does Weight Affect falling speed?
The simplest answer is: no, an object’s weight usually will not change its falling speed. For example, you can test this by dropping a bowling ball and a basketball from the same height at the same time–they should fall at the same speed and land at the same time.
Did Galileo know about gravity?
In 1589, Galileo conducted experiments with gravity, such as dropping balls from the Leaning Tower of Pisa; he discovered that they hit the ground at the same time despite having different weights.
Who discovered gravity?
Sir Isaac Newton
Who broke the law of gravity?
Naturally, human beings have had a basic understanding of this force since time immemorial. And when it comes to our modern understanding of gravity, credit is owed to one man who deciphered its properties and how it governs all things great and small – Sir Isaac Newton.
How did gravity get its name?
Our word gravity and its more precise derivative gravitation come from the Latin word gravitas, from gravis (heavy), which in turn comes from a still more ancient root word thought to have existed because of numerous cognates in related languages.
Did Einstein discover gravity?
In 1915, after eight years of sorting his thoughts, Einstein had dreamed up (literally–he had no experimental precursors) an agent that caused gravity. And it wasn’t simply a force. According to his theory of General Relativity, gravity is much weirder: a natural consequence of a mass’s influence on space.
