 * Water Droplets** is a photo being used for Ms. Rabold's physics in pictures project. This picture is being used because it features a water droplet on the edge of a clay pot and below it is a smaller water droplet falling from the edge of it. It grows in size and the further down it goes, the further away it gets from the first, and smallest drop.
 * **Contents**

Velocity, by definition, is the rate of change of a position of a body in a specified direction. The equation for velocity is =V= △X / △Y= The picture shows a water droplet that is falling from the edge of the pot. As the water droplet falls, its velocity increases because of the acceleration of gravity that it experiences. The further that it gets from it's origin point, the faster that it gets until it reaches its terminal velocity, which is the fastest that it will go as it's falling.

=**Refraction of Light in Water**=

In this picture, there is the reflection of the light in the water droplet. This is called water refraction, which is when the direction of the wave changes. The refraction, when looking at the object, is one because the light refraction of air is one. Water, however, has a refractive index of 1.3. When you look into a bowl of water, or in this case when you're looking at the water droplets, the object is reflected because the light rays are being bent when they pass through the air and into the water.

=Gravity=

Gravity is the pull of an object of a lesser towards the earth. The acceleration of gravity is 10, and the picture the water droplet is falling from the larger droplet towards the ground. It is accelerating at a steady rate of 10 m/s, and as the droplet falls it gains speed. The gravitational force of the water droplet is greater than the one that the original droplet has on the one that is falling, thus the droplet is falling to the ground instead of going up and rejoining the original droplet. =**See Also**=
