Questions 1. What is the goal of science? The major goal of science is to ask & answer questions about the physical universe that we live in. How is observation different from imagination? Observation gathers only what data is obviously true. Imagination can go anywhere—factual …

Gravity, or gravitation, is a natural phenomenon by which all things with mass or energy—including planets, stars, galaxies, and even light—are attracted to one another. On Earth, gravity gives weight to physical objects, and the Moon's gravity causes the tides of the oceans.

Information
Acceleration: about 9.8 metres
Causes
Objects with mass have gravity. Gravity also gets weaker with distance. So, the closer objects are to each other, the stronger their gravitational pull is. Earth's gravity comes from all its mass.
Units
The gravity of Earth, which is denoted by g, refers to the acceleration that the Earth imparts to objects on or near its surface. In SI units this acceleration is measured in metres per second squared (in symbols, m/s2) or equivalently in newtons per kilogram (N/kg).
Roles
Gravity
is the powerful force that glues our universe together. Gravity helped form our solar system, the planets, and the stars. It holds the planets in orbit around the Sun, and moons in orbit around the planets. The gravitational pull of the Sun and Moon creates the tides on Earth.
Velocity
Gravity causes an object to fall toward the ground at a faster and faster velocity the longer the object falls. In fact, its velocity increases by 9.8 m/s2, so by 1 second after an object starts falling, its velocity is 9.8 m/s.
Gravity game
Gravity is the force by which a planet or other body draws objects toward its center. The force of gravity keeps all of the planets in orbit around the sun. Earth's gravity is what keeps you on the ground and what makes things fall.The force of gravity comes from the mass of an object. The more mass an object has, the more gravity it has. Gravity also gets weaker with distance. So, the closer objects are to each other, the stronger their gravitational pull is.Earth's gravity comes from all its mass. All its mass makes a combined gravitational pull on all the mass in your body. That's what gives you weight. And if you were on a planet with less mass than Earth, you would weigh less than you do here.Gravity is also what keeps the moon in orbit around Earth. Earth's gravity pulls on the moon and keeps it from flying off into space.The force of gravity is always attractive. It never pushes things apart.
Why is gravity so important?
Gravity is one of the fundamental forces of the universe. It is the force that attracts objects to each other. Without gravity, the universe would be a very different place.Gravity is what gives objects mass. It is also responsible for the orbits of planets and stars. Without gravity, the universe would be a very different place.
Can you explain gravity to me?
Gravity is a force of attraction between objects. The more massive an object is, the more gravity it has. Gravity also gets weaker with distance. So, the closer objects are to each other, the stronger their gravitational pull is.Earth has more gravity than the moon. That's why people weigh more on Earth than they do on the moon. And it's why the moon orbits around Earth instead of flying off into space.Gravity is also what keeps you glued to the ground. If you jump up, gravity pulls you back down again. It's also what makes things fall.Gravity is caused by mass. The more mass an object has, the more gravity it has. That's why the Earth has more gravity than the moon. The Earth has more mass than the moon.Mass is the amount of matter in an object. Matter is the stuff that all things are made of. Atoms are the smallest bits of matter.Earth has more gravity than the moon because it has more mass. The more mass an object has, the more gravity it has.The force of gravity is also weaker at a distance.

What are 5 facts about gravity?
Gravity is the force by which a planet or other body draws objects toward its center. The force of gravity keeps all of the planets in orbit around the sun. Earth's gravity is what keeps you on the ground and what makes things fall.Without gravity, we would float off into space. The force of gravity is what gives us weight. If you were on a planet with less gravity than Earth, you would weigh less than you do here. If you were on a planet with more gravity, you would weigh more.Earth's gravity comes from all its mass. All its mass makes a combined gravitational pull on all the mass in your body. That's what gives you weight. And if you were on a planet with less mass than Earth, you would weigh less than you do here.Gravity is also what keeps the moon in orbit around Earth. And it's what makes it possible for us to have tides. The moon's gravity pulls on the oceans, causing the tides.These are just a few of the many things that gravity does. It's a fascinating force, and scientists are still learning about all its effects.
