Acceleration due to Gravity-FAQs
What do you mean by Acceleration due to Gravity?
Acceleration due to Gravity is defined as the acceleration attained by an object due to the gravitational force of attraction. When a body is fallen toward the earth it experiences a change in its acceleration due to the gravitational pull (or force) of the Earth.
What is the SI unit and dimensional formula of Acceleration due to Gravity?
The SI unit of Acceleration due to Gravity is m/s2. And the dimensional formula of Acceleration due to Gravity is [ML0T-2].
What is the acceleration due to gravity on the moon?
The value of acceleration due to gravity on the moon is 1.625 m/s2.
Does the mass of any object have an impact on the value of acceleration due to gravity?
No, mass does not have any significant impact on the value of acceleration due to gravity.
Write down the formula to calculate the attraction force between two objects.
The formula to calculate the attraction force between two objects is given by,
F = GMm/ R2
where,
- m and M are the masses of the objects in contact,
- G is the Gravitational Constant and
- R is the distance between them.
What do you understand by the term Free Fall?
A body is said to be in free fall when it only moves with respect to the Earth’s gravity. An external force exerted on the ball will cause its motion to accelerate. Gravitational acceleration is another name for this rate of free fall.
What is the value of acceleration due to gravity on Earth?
The value of acceleration due to gravity on the surface of Earth is approximately 9.8 m/s2 . This value varies slightly depending on factors such as altitude, latitude, and local geology.
Who discovered the concept of acceleration due to gravity?
The concept of acceleration due to gravity is commonly attributed to Sir Isaac Newton.
How is acceleration due to gravity calculated?
Acceleration due to gravity can be calculated using the formula g=F/M, where F is the force of gravity acting on an object and m is the mass of the object.
Does acceleration due to gravity depend on the mass of an object?
No, according to the principle of equivalence, acceleration due to gravity is independent of the mass of an object
How does altitude affect acceleration due to gravity?
At higher altitudes, acceleration due to gravity decreases slightly due to the increased distance from Earth’s center and the distribution of mass in the Earth’s interior.
What are some practical applications of acceleration due to gravity?
Acceleration due to gravity has numerous practical applications, including:
- Determining the weight of objects by measuring the force of gravity acting on them.
- Calculating the trajectory of projectiles in ballistic motion.
Acceleration due to Gravity
Acceleration due to gravity (or acceleration of gravity) or gravity acceleration is the acceleration caused by the gravitational force of attraction of large bodies. As we know that the term acceleration is defined as the rate of change of velocity with respect to a given time. Scientists like Sir Isaac Newton and Lord Henry Cavendish soon discovered that this increase in speed, or acceleration, was caused by a different force known as gravity by studying objects falling to the Earth in a variety of circumstances.
According to definitions, gravity is a force that pulls objects toward the center of mass, like the Earth. Conversely, acceleration describes how an object’s velocity or speed changes over time. Hence, the value of acceleration due to gravity is 9.8 m/s2 on earth.
