Acceleration

This is my friend Tyler and his board. As you can see really likes boogie boarding, so while out catching waves I realized that there's an increase in acceleration as the wave carries you through the water! Acceleration is the change in speed/velocity, whether it's increasing or decreasing. So it can be through increase in speed, decrease in speed, or change in direction. There are many factors that can affect the acceleration of the board, such as direction whether you're going straight, to the side, or stopping yourself. 
A (acceleration) is equal to delta v (change in velocity) over delta t (change in time), since it's based on velocity which speed in a given direction. It could be written as 1 m/s^2 because if you set up the equation you would end up with meters over seconds squared. He accelerated through the water by increasing speed as the waves got closer the shore, also accelerating when he turned back or changed directions in the water to either stop, or go back through the wave to avoid the rocks. I love the beach and Physics really has taught me to look at all the little things and to see that science is all around us!
