Have you ever heard of the velocity equation? If not, don’t worry; this article will help you understand what it is all about. First, let’s define what is velocity. For our purposes, velocity is any change in an entity’s speed at a particular time. Remember that this definition only works if an entity has a permanent velocity in a constant straight line direction or if you would like to measure the average velocity over some defined distance (in comparison to the instant velocity).
For our purposes, the definition of velocity is the change in velocity that an object experiences over time, in comparison to the speed it was initially moving. How long ago did the change in velocity happen? Well, for a perfect sphere, it would take the same amount of time regardless of what direction it traveled.
Now, let’s take a look at the relationship between velocity and acceleration. The relationship is one which is well-known and used almost on a daily basis. It can be stated that the higher the acceleration, the greater the speed (or change in velocity). For example, while accelerating at 35 mph, the distance travelled would be much greater than at the same speed using a vertical jump. In fact, this is exactly what happens when you jump from a high jump height. However, for our purposes here, we will just look at the change in velocity between different types of motions.
A change in velocity has a corresponding change in acceleration. This is why when you see a force acting on an object, you always see it accelerate. The reason for this is that it must overcome the effect of its own momentum, which changes the magnitude of the force along with it. The magnitude of a force is the same as its acceleration. So, the bigger the magnitude of the force, the larger the change in acceleration will be when it comes to moving with it.
When we talk about the motion of a system at different speeds, what is meant by ‘speed’ is the rate at which the system is changing. Imagine two boxes at different distances being accelerated toward a reference point. Once they reach the reference point, the boxes will have altered their direction of rotation. Now, if you remove the reference point, and move the boxes back toward each other, you will get a comparison of the change in velocity of the systems.
This may seem complicated, but remember that everything behaves in similar ways once you remove the influence of gravity and the effect of local terrestrial gravity. What you are looking at is a comparison of magnitude versus acceleration. This is true for all fluids, including water. The standard unit of measurement for velocity is the meter/s. You may convert this to miles per hour by multiplying the standard unit with the horizontal distance, which is the distance between the lowest point on the surface of the water vessel and the highest point on the surface, or bottom and top, or by multiplying the horizontal distance with the vertical distance.
Your car has a speed of 60 miles per hour when it is traveling down the highway. That is its general speed, although you may not notice the difference in the constant speed, which is how much faster it goes as it approaches a bend in the road. If you put the car on the tracks and accelerated from a stationary position, the speed would be much shorter, because of the G-force created by the wheels. If you measure the distance between the lowest point on the surface of the water vessel to the highest point on the vehicle, you will get a measurement in meters per second, and that is the definition of velocity.
A continuous motion picture is one where the motion does not change, so that what is written is a constant velocity. An increasing or decreasing velocity is called a variable velocity. In the case of increasing velocity, the direction of motion remains unchanged, while in the case of decreasing velocity, the direction of motion changes. Variable velocity is often seen in Physics as a force acting between two or more objects.
