The video tutorial explains gravitational acceleration and how to calculate it for different celestial bodies. It starts with an example of calculating the gravitational acceleration on the moon using its mass and radius. The tutorial then moves on to calculate the gravitational acceleration on the Earth's surface and at a distance above it, demonstrating how gravity decreases with distance. Finally, it covers how to determine the mass of a planet using its gravitational acceleration and radius, using Planet X as an example.
