What description explains the situation where an elephant and a feather are falling from a high building?
In the absence of air resistance, both the elephant and the feather are in a state of free-fall. That is to say, the only force acting upon the two objects is the force of gravity. This force of gravity is what causes both the elephant and the feather to accelerate downwards.
When comparing an elephant and a feather The elephant has a greater acceleration because it has more mass?
The feather weighs more, and therefore will not accelerate as rapidly as the elephant. 8. Both elephant and feather weigh the same amount, yet the greater mass of the feather leads to a smaller acceleration. 9.
Is gravity different for ants?
How Do They Get Away With It? Actually, flies and ants need to obey the same law of gravity that we do. Because household insects weigh so much less than we do, it takes only a very small amount of force to overcome gravity and keep them stuck to the wall or ceiling.
Is it possible for a mouse to have the same momentum as an elephant?
Yes, an elephant could have the same momentum as a mouse despite the fact that an elephant is thousands of times larger than a mouse.
Can you determine the acceleration due to gravity by dropping a feather Why or why not?
A hammer and a feather will fall with the same constant acceleration if air resistance is considered negligible. This is a general characteristic of gravity not unique to Earth, as astronaut David R. The acceleration of free-falling objects is therefore called the acceleration due to gravity.
Does an elephant and a feather have the same force of gravity?
Both elephant and feather have the same force of gravity, yet the feather experiences a greater air resistance. Each object experiences the same amount of air resistance, yet the elephant experiences the greatest force of gravity.
What is true about acceleration due to gravity?
A free-falling object has an acceleration of 9.8 m/s/s, downward (on Earth). The numerical value for the acceleration of gravity is most accurately known as 9.8 m/s/s. There are slight variations in this numerical value (to the second decimal place) that are dependent primarily upon on altitude.
Why can’t we measure an elephant’s momentum?
We may not be able to measure their weight because of the lack of significant gravitational pull, but they still have mass. This means that they will have momentum, since p (momentum) = mass x velocity. Going at the same speed, the elephant, having more mass, will have much more momentum.
How does gravity affect the mass of an object?
So, the closer objects are to each other, the stronger their gravitational pull is. Earth’s gravity comes from all its mass. All its mass makes a combined gravitational pull on all the mass in your body. That’s what gives you weight.
What does the strength of the gravitational force depend on?
The strength of the gravitational force depends on the mass of the object and its proximity to the Earth. The larger and closer the object, the greater the gravitational pull. Gravitational force on the Earth cause objects to accelerate when they fall.
How does gravity change with distance from the Earth?
Gravity also gets weaker with distance. So, the closer objects are to each other, the stronger their gravitational pull is. Earth’s gravity comes from all its mass. All its mass makes a combined gravitational pull on all the mass in your body. That’s what gives you weight.
