Gravitational Potential Energy Concepts

This video tutorial by K Science explains gravitational potential energy and how to calculate it using the equation E = M * G * H, where E is energy, M is mass, G is gravitational field strength, and H is height. The tutorial includes examples with a bird on the ground and in flight, demonstrating how changes in height affect energy. Viewers are encouraged to practice with questions and explore additional resources.

What is the basic equation for calculating gravitational potential energy?

• E = M * G * H

• E = M + G + H

• E = M / G / H

• E = M - G - H

Which of the following represents the gravitational field strength on Earth?

• 17 Newtons per kilogram

• 23 Newtons per kilogram

• 1.3 Newtons per kilogram

• 9.8 Newtons per kilogram

If a bird is standing on the ground, what is its gravitational potential energy?

• 0 Joules

• 17 Joules

• 1.3 Joules

• 9.8 Joules

What changes when a bird flies to a higher altitude?

• Mass

• Gravitational field strength

• None of the above

• Height

How does the gravitational potential energy change as the height of the bird increases?

• It remains the same

• It becomes zero

• It decreases

• It increases

What is the gravitational potential energy of a bird at 17 meters above the ground?
