Physics of Jumping and Gravity

The video explores the concept of hang time, using Michael Jordan's famous dunk as an example. It explains how gravity affects hang time and introduces a quadratic equation to model it. The video further analyzes how hang time would differ on other celestial bodies like Venus, Jupiter, and the Moon, highlighting the impact of varying gravitational forces.

What did Michael Jordan say about his feeling when he is in the air?

• He feels like he has to come down immediately.

• He feels like he can fly forever.

• He feels like he never has to come down.

• He feels like he is falling.

What is the human limit for hang time on a flat surface?

• About 0.5 seconds

• About 1 second

What is the gravitational acceleration on Earth?

• 9.8 meters per second squared

• 24.92 meters per second squared

• 8.87 meters per second squared

Which equation models the height of a falling object?

• Initial height + initial velocity * time + 0.5 * gravity * time^2

• Initial height - initial velocity * time + 0.5 * gravity * time^2

• Initial height + initial velocity * time - 0.5 * gravity * time^2
