Terminal Velocity

The video tutorial explains gravity as a force that accelerates objects towards Earth at 9.8 m/s². It introduces the concept of terminal velocity, where an object stops accelerating due to air resistance balancing gravitational force. The tutorial also discusses how parachutes increase drag, reducing terminal velocity for a safe landing.

What is the rate at which gravity accelerates objects towards Earth?

• 9.8 meters per second squared

• 5 meters per second squared

• 12 meters per second squared

• 54 meters per second squared

What happens to an object when it reaches terminal velocity?

• It decelerates rapidly

• It stops accelerating and maintains a constant speed

• It starts moving upwards

• It continues to accelerate

At approximately what speed does a human reach terminal velocity when falling?

• 121 meters per second

• 54 meters per second

• 9.8 meters per second

• 5 meters per second

How does a parachute help in landing safely?

• By increasing gravity

• By decreasing drag

• By increasing speed

• By increasing drag

What is the new terminal velocity with a parachute deployed?

• 54 meters per second

• 121 meters per second

• 9.8 meters per second

• 5 meters per second
