Why is the gravitational acceleration of any object near Earth the same no matter what the mass of the object is?
Explain why the gravitational acceleration of any object near Earth is the same no matter what the mass of the object is. Newton’s second law shows that acceleration depends on both force and mass. Since F=ma or a=f/m), if F is increased at the same rate as m, then a remains the same.
Why is gravitational acceleration same for all objects?
the value of g is 9.8 meters per square second on the surface of the earth. The gravitational acceleration g decreases with the square of the distance from the center of the earth. So all objects, regardless of size or shape or weight, free fall with the same acceleration.
Why do objects accelerate at the same rate?
Overview. Gravity is a force that pulls objects down toward the ground. Gravity causes an object to fall at a faster and faster velocity the longer the object falls. All falling objects accelerate at the same rate due to gravity unless air resistance affects one more than another.
Why is the gravitational force between two objects the same?
Since the gravitational force is directly proportional to the mass of both interacting objects, more massive objects will attract each other with a greater gravitational force. So as two objects are separated from each other, the force of gravitational attraction between them also decreases.
What is the acceleration near Earth’s surface cause by?
gravity
An object dropped near Earth’s surface will accelerate downwards at about 9.8ms2 due to the force of gravity, regardless of size, if air resistance is minimal.
What does the gravitational acceleration of an object have?
It was learned in the previous part of this lesson that a free-falling object is an object that is falling under the sole influence of 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.
Is gravitational acceleration the same everywhere on Earth?
Gravity is often assumed to be the same everywhere on Earth, but it varies because the planet is not perfectly spherical or uniformly dense. In addition, gravity is weaker at the equator due to centrifugal forces produced by the planet’s rotation.
Is the gravitational force the same for all objects?
On earth, all objects (whether an elephant or a feather) have the same force of gravity. The elephant weighs more than the feather, yet they each have the same mass.
Why do the two masses have the same acceleration?
I said the two masses have the same acceleration because the tension throughout the string is equal. The combined mass pulls each other at the same rate becauseb oth have the same foreces acting upon them.
Do all objects have the same gravitational force?
Is the gravitational force always the same?
The size of the gravity force at an altitude of 200km is still about 94% of what it was at sea level.) The gravity force on an object from the Earth is the same regardless of whether the object is surrounded by air (or water or anything else).
What is the acceleration due to gravity near the Earth’s surface?
9.8 m/s2
Its value is 9.8 m/s2 on Earth. That is to say, the acceleration of gravity on the surface of the earth at sea level is 9.8 m/s2. When discussing the acceleration of gravity, it was mentioned that the value of g is dependent upon location. There are slight variations in the value of g about earth’s surface.
