A person would be squashed by gravity on Mars if there were a large slab of rock
on top of him.
The acceleration of gravity on Mars is 3.77 meters per second2 ... about 38% of
its value on Earth. So an astronaut who weighs 200 pounds with all his gear on
Earth would have to drag around 76 pounds on Mars.
Not at all! Since Uranus is gaseous rather than solid, its force of gravity is actually less than Earth's. If you weighed 100 pounds on Earth, you would weigh 86 pounds on the surface of Uranus, if you could find some place to stand on. You would freeze to death on Uranus, though, as the temperature is around -300 degrees F.
Yes, in this context, the force acting opposite to the man climbing the mountain would be the force of gravity, which pulls the man downward towards the Earth. The man must exert force to overcome gravity and climb the mountain.
Gravity is indeed a force, but only one out of many. magnetic, frictional, mechanical ... . When an ordinary force applied to an object, (me pushing my wheelbarrow) this would not be considered as being affected by gravity.
That's "centrifugal force". It's not a "real" force like gravity, but is a convenient way of describing the effect of the inertia of the planets. (The planets would move in straight lines if they were not in a gravity field.)
8,9 m/s2 The gravitational attraction on the surface of Venus.
On Uranus, you would choke, be squashed, and burn up.
Yes, the gravity on Venus is about 91% of the gravity on Earth. So, a human on Venus would not be significantly squashed by the gravity, but they would feel heavier than on Earth due to the increased gravitational force.
Gravity pulls objects toward the center of the Earth. However, the ground provides an upward force called "normal force" that counteracts gravity, keeping us from being squashed into the ground. This balance between gravity and the normal force allows us to stand and move on the Earth's surface.
The force that causes someone to speed up as they fall is gravity. Gravity is the force of attraction between two objects with mass, pulling them towards each other.
Yes, there can be negative gravity. If a gravity is a pulling force then in the other hands a negative gravity would be a pushing force, in other words, the negative gravity would push us to wherever and the positive gravity on Earth would pull us.
The force that brings someone back to the ground after jumping is the force of gravity. Gravity pulls downwards on the person, counteracting the force generated by their jump and causing them to descend back to the ground.
Not at all! Since Uranus is gaseous rather than solid, its force of gravity is actually less than Earth's. If you weighed 100 pounds on Earth, you would weigh 86 pounds on the surface of Uranus, if you could find some place to stand on.

The weight of the object would change if gravity changes. cw: Yes, if the FORCE of gravity changes, the FORCE of the object in the downward direction changes.
When there is no net force of gravity, all the opposing forces of gravity cancel out. For example, most of the way to the moon, the gravity pulling from the moon would cancel out the gravity from the Earth. At that point, there would be no net force of gravity. KEEP IN MIND, that this is something very different from the weightless feeling you get when falling. When falling, gravity still affects you (hence you accelerate downwards). If there is no net force of gravity, gravity will not affect you at all.
There would be no gravity so we all would die as the gravitational force pulls out when no gravity
No. Gravity is a property of matter that produces force. But there's no way a force is going to 'become' gravity, although a constant linear acceleration would be indistinguishable from gravity.
If the Earth would be a perfect sphere, you would experience no gravity in the center because all the mass around you would pull at you with the same strength in all directions, netting you a zero total force.
