Does gravity get stronger or weaker the higher you go?

gravity increases with height. gravity is significantly less on high mountains or tall buildings and increases as we lose height (which is why falling objects speed up) gravity is caused by the Earth spinning. gravity affects things while they are falling but stops when they reach the ground.

Does gravity have to be stronger than lift to keep the plane up?

Each force has an opposite force that works against it. The plane goes up if the forces of lift and thrust are more than gravity and drag. If gravity and drag are bigger than lift and thrust, the plane goes down. Just as drag holds something back as a response to wind flow, lift pushes something up.

What causes the force of gravity to weaken?

Objects with more mass have more gravity. Gravity also gets weaker with distance. So, the closer objects are to each other, the stronger their gravitational pull is. All its mass makes a combined gravitational pull on all the mass in your body.

What happens if lift is more than weight?

If lift is greater than your weight, the plane shifts upward. If thrust is greater than drag, the aircraft will speed up, and subsequently, if drag is greater than the thrust, you’ll slow down. Lift is the force that counteracts the weight of an object in order to keep it in the air.

What if the Earth was twice as massive?

If Earth’s diameter were doubled to about 16,000 miles, the planet’s mass would increase eight times, and the force of gravity on the planet would be twice as strong. Life would be: Built and proportioned differently.

Can the moon affect your weight?

The force gravity exerts on a person determines the person’s weight. Even though your mass would be the same on Earth and the moon, if you weigh 132 pounds (60 kilograms) on Earth, you would weigh about 22 pounds (10 kilograms) on the moon.

How much work does lifting a heavy weight actually do?

When we lift the weight, we generate the force needed to counteract gravity by contracting and relaxing many fibers in our muscles constantly. If this contracting/relaxing was purely mechanical, it might do just a little work (not 0 because some kinetic energy will be lost to friction, but almost).

What is the difference between gravity and force exerted by man?

Unlike gravity, the force exerted by the man is in general not constant, does not depend only on position of the body (you may apply different force on the weight at the same height h on the way up vs. on the way down), and is not conservative (does not arise from a potential).

Are weightlifters reaching their maximum potential?

“If you look over time at the records for maximal lifts, they have crept up but are starting to plateau,” he says. “Today’s weightlifters, including those that use steroids, are near the limit of human potential.” It is the muscles that set the limit.

Should you use heavier weights to get stronger?

If you’re looking to get as strong as possible, you’ll be using a heavier weight than someone who is trying to get as big as possible. And to improve muscular endurance, you’ll use an even lighter weight. Strength training means choosing weights that allow you to train in a rep range of 1-6.
