Gravity

Projectile motion and satellite motion both involve an object moving through a gravitational field. However, satellites are in a state of continuous free fall around a celestial body, while projectiles follow a parabolic path with a defined initial velocity and angle. Additionally, satellites have a stable orbit due to their speed and altitude, while projectiles experience a temporary motion before returning to the ground.

Sir Isaac Newton, the English Mathematician and Physicist who created the

theory of gravity that explained the effects of it that we see around us, called

it "Universal Gravitation".

Humans have developed adaptations such as bipedalism, strong musculature, and a well-developed inner ear system to help overcome the force of gravity. These adaptations allow us to walk upright, maintain balance, and resist the pull of gravity on our bodies. Additionally, advancements in technology like transportation and aerospace engineering have provided further means to mitigate the effects of gravity on human activities.

Gravity is the force that keeps Earth in orbit around the Sun. The gravitational pull between the two objects causes Earth to move in a curved path around the Sun, creating the elliptical shape of its orbit. Without gravity, Earth would not be able to stay in its orbit and would drift off into space.

The sun (Sol), like any star, gained so much mass (of mainly hydrogen, with some helium and lithium) that its core began a fusion reaction. Without gravity, it would not have had enough mass, and by extent pressure, to sustain fusion, and therefore would not be a star.

Yes, altitude can affect specific gravity and density due to variations in atmospheric pressure. As altitude increases, atmospheric pressure decreases, leading to a decrease in density and specific gravity of gases and substances. This is important to consider when measuring and calculating these properties at different elevations.

100 pounds on earth surface = 37.8 pounds on mars surface

Mass remains the same though.

The (centripital) force due to rotation is at its greatest at the equator, if you weigh 100 kg, the force of gravity on you = approx. 982 n anywhere on earths surface, the centripetal force at the equator = 3.4 n

Sir Isaac Newton is credited with discovering the law of gravity. He formulated the law of universal gravitation, which explains the force of gravity acting between all objects in the universe.

The source of gravity on the Moon is its mass. Gravity is a force that attracts objects with mass towards one another, and the amount of gravity depends on the mass of an object. The Moon's gravity is about 1/6th of Earth's gravity due to its smaller mass.

The object that exerts the force on another object is called the "force" or the "acting force."

No, essentially mass = gravity

the earths mass is roughly 81 * that of the moon, if you stood at the same distance from both, the force on you from the earth would be 81 * that of the moon.

The moon's gravity pulls on the Earth, causing ocean tides to rise and fall. It also creates tidal forces that slightly deform the Earth's shape and slow down its rotation. Additionally, the moon's gravitational pull helps stabilize Earth's axial tilt, which is important for our planet's climate and seasons.

Astronauts in space experience microgravity, where they are in a state of continuous free fall around the Earth. This creates the sensation of weightlessness. They do not completely overcome gravity, but rather experience an environment where the effects of gravity are significantly reduced due to the spacecraft's orbital motion.

Gravity pulls down on all air masses, including ones that contain clouds. But the cooler air masses are closer to the ground because they are denser (contain more molecules per volume) and displace the warmer air, which in effect rises. This warm air contains the water vapor that forms cloud droplets as it rises and cools. Eventually much of the cloud's water will condense into drops and fall back as rain.

The force of gravity on Jupiter is much stronger than on Earth due to Jupiter's larger mass. Jupiter's gravity is about 2.5 times that of Earth.

The Moon does have gravity, but its gravitational force is only about 1/6th that of Earth's. This is because the Moon is much smaller and less massive than Earth. The effect of gravity on the Moon is still strong enough to affect objects, including causing tides on Earth.

If the gravitational pull got three times stronger, your weight would also increase by three times. This means that you would feel heavier and it would be more difficult to move around or lift objects. Your body would experience an increase in pressure on your joints and muscles, which could lead to discomfort or fatigue.

If there was no gravity, the ball would not fall back down to the ground after being thrown. It would continue in a straight line with the same speed and direction it was thrown with until it was affected by another force.

Since there is no wind on the moon, any flag "flying" would have to be due to mechanical support -- exactly as was stated as having been done in 1969 (I recall that as I watched the flag being "unfurled").

Galaxies do exert significant gravitational attraction on other galaxies. For example, the Greater and the Lesser Magellanic Clouds are galaxies that orbit our own galaxy, the Milky Way. In that sense, the stars in one galaxy do have a gravitational interaction with those in other galaxies. Of course, the more distant galaxies have correspondingly less gravitational interaction with ours.

The sun controls gravity in our solar system keeping the planets in orbit just as the earth keeps the moon in orbit. Depending on how close you are to a planet will determine whether the suns or that planets gravity will act upon you. Gravity is everywhere in space.

Albert Einstein first proposed the idea that gravity bends the fabric of space in 1911. He and David Hilbert fully developed it in a mathematical framework in late 1915. Arthur Eddington reported in 1919 that Einstein's predictions were correct, but there was controversy over whether his statements were valid. Measurements from the 1922 eclipse in Australia left no doubt but that Einstein was correct.

The acceleration due to gravity on Earth is approximately 9.81 meters per second squared (m/s^2). This value represents the rate at which an object accelerates towards the Earth when in free fall.
