### The Force of Gravity

Gravity is the force that makes things fall. Gravity is a force that pulls things to the ground. Gravity stops objects from floating up. Gravity holds things down.

Remember four things that forces can do:

1. Make an object start moving

2. Make an object stop moving

3. Change the speed of an object

4. Change the direction of a moving object

The force of gravity can do the same things.

### Gravity Makes an Object Start Moving

If you let go of a ball, the ball drops to the ground. You do not need to push the ball to make the ball fall. Gravity makes the ball start moving.

### Gravity Makes an Object Stop Moving

If you toss a ball up, the ball will soon start to fall. Before the ball starts to fall, the ball will stop in the air. The ball stops for a very short time. You do not see the ball stop. The force of gravity makes the ball stop going up.

### Gravity Changes the Speed of a Moving Object

When an object falls, the object moves faster and faster as it gets closer to the ground. Gravity makes things move faster as they get closer to Earth.

### Gravity Changes the Direction of a Moving Object

If you throw a ball to a friend far away, the ball starts to fall. The direction of the ball changes. The ball starts to fall down. Gravity changes the direction of the ball.
