Weightlessness occurs when an object quizlet app

Suppose you kick a soccer ball straight up to a height of 10 meters. Why are astronauts weightless in the Space Station? How does your weight compare to your normal weight on the ground? You are weightless whenever you are in freefall, and the Space Station and other objects orbiting Earth are in a constant state of freefall.

The planets never travel in a straight line as they orbit the Sun.

As long as the elevator is not accelerating, your weight on a scale in the elevator will be the same whether the elevator is on the ground or rising or falling at constant speed. I cannot even describe how much Course Hero helped me this summer. Share this link with a friend: The Sun would rotate faster than it does now.

It is the same. According to the law of conservation of angular momentum, what would happen? Because the planets are not traveling in straight lines, the planets are always accelerating, and Newton's second law tells us that a force must be acting to cause the acceleration. University of California, Los Angeles.

Therefore both objects will fall at the same rate and

And because there is no air on the Moon, they'll hit at the same time no matter what shape or density they have. You've reached the end of this preview. Because the Space Station is constantly in free-fall around the Earth. Therefore both objects will fall at the same rate. Therefore both objects will fall at the same rate and. Force is actually defined as the rate of change in momentum. Which of the following explains why you would be burned by sticking your hand briefly in the pot but not by sticking your hand briefly in the oven?

Gravitational potential energy is greater at for a larger height because the ball has a greater distance that it can fall and it accelerates as it falls.

This preview shows 2 out of 4 pages. Suppose you are in an elevator that is traveling upward at constant speed. The ball's gravitational potential energy is greatest at the instant when the ball is at its highest point. Other Related Materials 9 pages. Ask a homework question - tutors are online.
