## FAQs on Acceleration Due to Gravity above the Surface of Earth Video Lecture - Physics for JEE Main & Advanced

 1. What is the value of acceleration due to gravity above the surface of Earth?
Ans. The value of acceleration due to gravity above the surface of Earth decreases as we move away from the Earth's surface. However, it still follows an inverse square law. The most commonly used value for this acceleration is approximately 9.8 m/s^2 on the surface of Earth, but it decreases with increasing altitude.
 2. How does the acceleration due to gravity change with altitude above the surface of Earth?
Ans. The acceleration due to gravity decreases with increasing altitude above the surface of Earth. As we move away from the Earth's surface, the gravitational force between an object and the Earth weakens. This decrease in gravitational force results in a lower acceleration due to gravity.
 3. Does the acceleration due to gravity vary at different locations above the surface of Earth?
Ans. Yes, the acceleration due to gravity varies slightly at different locations above the surface of Earth due to variations in the Earth's mass distribution. Factors such as mountains, ocean trenches, and density variations in Earth's interior can cause small variations in the acceleration due to gravity.
 4. How does the acceleration due to gravity affect the motion of objects above the surface of Earth?
Ans. The acceleration due to gravity affects the motion of objects above the surface of Earth by pulling them towards the Earth's center. This acceleration determines how fast an object will fall or how much it will accelerate when released from rest. Objects in free fall experience an acceleration due to gravity that causes them to accelerate downwards at a constant rate.
 5. Is the acceleration due to gravity the same on other celestial bodies in the universe?
Ans. No, the acceleration due to gravity is not the same on other celestial bodies in the universe. It varies depending on the mass and radius of the celestial body. For example, the acceleration due to gravity on the Moon is about 1/6th of that on Earth, while on larger planets like Jupiter, it is much stronger. Each celestial body has its own unique acceleration due to gravity.
