how do you find speed in science. Speed is dependent on the amount of. Average speed can be calculated by dividing the total distance the object travels by the total amount of time it takes to travel that distance.

The speed of an object can be calculated from the gradient of its distancetime graph. This will give you your average speed. In this instance you need to set up a series of ratios to convert from different units until you reach the speed in terms of meters per second.
D the distance goes in the top of the triangle S speed goes in the bottom left of the triangle.
Miles per hour is a common measure of speed in the United States and is known as the English system but in other countries and in science and engineering the metric system is often used instead. Instantaneous velocity is defined as the rate of change of position for a time interval which is very small almost zero. Sometimes however you will be given a rate of speed in other units such as miles per hour. Average speed is measured in units of distance per.
