## FAQs on Acceleration Due to Gravity Video Lecture - Physics Class 11 - NEET

 1. What is acceleration due to gravity?
Ans. Acceleration due to gravity refers to the acceleration experienced by an object when it falls freely under the influence of gravity. It is a constant value, approximately 9.8 meters per second squared (m/s²), near the surface of the Earth.
 2. How is the acceleration due to gravity calculated?
Ans. The acceleration due to gravity can be calculated using the formula g = G * M / R^2, where g is the acceleration due to gravity, G is the gravitational constant (approximately 6.674 × 10^-11 N*m²/kg²), M is the mass of the celestial body (e.g., Earth), and R is the distance between the center of the celestial body and the object.
 3. Does acceleration due to gravity vary on different celestial bodies?
Ans. Yes, the acceleration due to gravity varies on different celestial bodies. It depends on the mass and radius of the celestial body. For example, the acceleration due to gravity on the Moon is approximately 1/6th of that on Earth, while on Mars it is about 1/3rd.
 4. How does altitude affect acceleration due to gravity?
Ans. As altitude increases, the acceleration due to gravity decreases. This is because the distance between the object and the center of the Earth increases, resulting in a weaker gravitational force. However, this decrease is relatively small for small changes in altitude near the Earth's surface.
 5. How does the shape of an object affect the acceleration due to gravity?
Ans. The shape of an object does not significantly affect the acceleration due to gravity. As long as the object's mass and distance from the center of the celestial body remain the same, the acceleration due to gravity will be constant. The shape of an object primarily affects its air resistance or buoyancy in a fluid medium, but not its acceleration due to gravity.
