There are different types of velocities in the science of Physics, which play different roles in our everyday life. People get confused with different types of velocities there are and the meaning of each and every one of them. Thanks to physics Physics we are able to see velocity, scalar and vector quantities, initial and final velocities, average velocity, and most importantly, constant and changing velocity. These are different types of velocities in physics and people get confused on them because their meanings are very similar or very confusing, but all these velocities play big roles in the science of physics.
Velocity is different from speed even though they both have similar meanings. Speed tells you how fast an object is moving and it’s the rate of change in position. Velocity and speed both tell the fastness of an object, but velocity also tells the object’s direction as well. An example of velocity is that an object is moving at 30 meters per second towards the southwest direction. In order to find velocity we divide distance traveled by time. The reason why this is an example of velocity is because it gives us the speed and the direction towards which the object is moving. Since velocity tells us the speed and the direction it’s known as a vector quantity.
A vector quantity, such as velocity, tells us about the magnitude and direction. Another vector quantity is force, which may be confusing to some people. The other type of quantity is scalar quantity, which is very similar to a vector, except for the fact that a scalar quantity only has a magnitude, but no direction. A vector wouldn’t be considered a scalar because it only tells us the magnitude. An example of the scalar quantity is speed.
Another type of velocity that people get confused on is initial and final velocity. Initial velocity and final velocity are the velocities a moving object has at the beginning and at the end of the motion, respectively. An example of an initial velocity would be if a car starts its motion from the rest, then its initial velocity is zero meters per second. People get confused with the final and initial velocity because they overthink it or they switch the final and initial velocity.
