How does gravity affect objects in our universe?

Gravity in our universe Gravity is what holds the planets in orbit around the sun and what keeps the moon in orbit around Earth. The gravitational pull of the moon pulls the seas towards it, causing the ocean tides. Gravity creates stars and planets by pulling together the material from which they are made.

What does the force of gravity affect?

Objects on Earth are pulled toward the center of Earth. The force of gravity, like all other forces, can cause changes in the speed of objects. Gravity can also cause an object that is thrown into the air to change its upward motion, slow down, and fall back toward Earth’s surface.

Does gravitational force affect the motion of an object?

When objects fall to the ground, gravity causes them to accelerate. Acceleration is a change in velocity, and velocity, in turn, is a measure of the speed and direction of motion. Gravity causes an object to fall toward the ground at a faster and faster velocity the longer the object falls.

How does gravity affect matter?

Gravity is a force pulling together all matter (which is anything you can physically touch). The more matter, the more gravity, so things that have a lot of matter such as planets and moons and stars pull more strongly. The more massive something is, the more of a gravitational pull it exerts.

Can we see the force?

We can’t actually see forces, but we see their effect on objects. We see the Moon orbit the Earth, objects fall to the ground, and birds fly – all of these are because of forces. named after Sir Isaac Newton (1642 – 1727).
