Asked by Juliet

When an object is moved from sea level to the top of a really high mountain, what, if anything changes about the weight of the object?

Could someone please help me explain this problem.

THANK YOU!!!

Weight is a force, and as described by Newton's Second Law, F=ma, where m=mass and a=acceleration. At sea level on Earth, the acceleration is 9.81m/s down, which is the pull of gravity. By taking the object up to the top of a high mountain, it will be less affected by the pull of gravity, so it will weigh less. This still follows Newton's Law: since acceleration has decreased, F must decrease, because the mass is always constant no matter where it is taken (on this planet, or off).
