# What is Speed?
<p>Speed is the rate of change in position of an object with respect to time. It is a scalar quantity, meaning it has only magnitude and no direction. <strong><a href="https://megfeed.com/what-is-speed/">Speed</a></strong> is measured in units of meters per second (m/s). An object's speed is the product of its velocity and the magnitude of its velocity vector.</p>
<h2>Unit of speed</h2>
<p>The unit of speed is the meter per second. This is the standard unit of speed and is used to measure the speed of objects in motion. The meter per second is a unit of speed that is used to measure the speed of objects in motion. This unit of speed is the standard unit of speed and is used to measure the speed of objects in motion.</p>
<h2>Example of speed</h2>
<p>Speed is the rate at which an object moves through space. It is a measure of how fast an object is moving. Speed can be measured in a number of ways, including by using a stopwatch or by measuring the distance an object travels in a given period of time.</p>
<p>For example, if a car is traveling at a speed of 60 miles per hour, it will travel 60 miles in one hour.</p>
<h2>What is the difference between speed and velocity and speed?</h2>
<p>The <strong><a href="https://megfeed.com/difference-between-speed-and-velocity/">difference between speed and velocity</a></strong> is that velocity is a vector quantity and has both magnitude and direction, while speed is a scalar quantity and only has magnitude. This means that, while you can express the speed of an object as a number, you need both a number and a direction to express its velocity. For example, if an object is moving north at 5 m/s, its velocity is 5 m/s north.</p>
<p>An object's speed is just the magnitude of its velocity vector. So, in the example above, the object's speed would be 5 m/s.</p>
<p>It's important to note that, while velocity is a vector quantity, speed is not. This means that, while you can add velocities together to find a resultant velocity, you cannot add speeds together.</p>
