In this part :
Gravity is the force that pulls objects with mass toward the center of Earth.
How does gravity affect the movement of objects ?
▌The force of gravity pulls objects down toward the ground, such as skydivers that fall down toward the ground.
▌The force of gravity between the Sun and objects in the solar system keeps the planets revolve in fixed orbits.
▌The gravity of the moon affects the ocean tides.

The Effect of Gravity on the Movement of Objects
Girl on a slide
• The force of gravity is pulling the girl and, as a result, she moves down the slide.
• If there were no gravity:
- There would be no force that pulls the girl downward.
- The girl would also not be held to the slide.

Revolving of the moon around Earth
• The force of gravity is pulling the moon, as a result, the moon still revolves in its orbit
around Earth.
• If there were no gravity between the moon and Earth,
the moon would just float off
into space.

Gravity
► Gravity pulls objects toward the center of Earth.
► Gravity affects two objects even when they do not touch each other, such as the moon and Earth.
► There is gravitational attraction (or gravitational pull) between Earth and the moon.

Mass and gravitational force
Gravitational force (gravity) of an object increases, as its mass increases and vice versa.
Distance and gravitational force
Gravitational force (gravity) decreases, when the distance between two objects increases and vice versa.
