Force of Gravity
Gravity is a force that always attracts or pulls objects toward each other without direct contact or impact
Gravitational attraction depends on the mass of the two objects and the distance they are apart.
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. As an object falls, its speed will continually increase as Earth’s gravity continually pulls it downward. When air resistance is ignored, all objects will speed up at the same rate as they fall.
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.
The pull of Earth’s gravity keeps the Moon in orbit; the moon is constantly changing direction because of gravity.
The force of gravity pulls objects to the center.
