Questions & Step-by-Step Solutions
Which of the following is true about the escape velocity from the surface of the Earth?
Step 1: Understand what escape velocity means. It is the speed needed to break free from the gravitational pull of a planet without any additional propulsion.
Step 2: Know that escape velocity does not depend on the mass of the object trying to escape. Whether it's a small rock or a large spaceship, the escape velocity remains the same.
Step 3: Realize that escape velocity does depend on the mass of the Earth. A larger mass means a stronger gravitational pull, which requires a higher speed to escape.
Step 4: Remember that escape velocity also depends on the radius of the Earth. A larger radius means you are further from the center of the Earth, which can lower the escape velocity.
