Velocity
Velocity is a term used to describe the rate of change of an object’s position in a specific direction
Velocity is a term used to describe the rate of change of an object’s position in a specific direction. It is a vector quantity, meaning it has both magnitude and direction. In physics, velocity is often denoted by the symbol “v.”
To calculate velocity, you need to know both the object’s displacement and the time it took for that displacement to occur. The formula for velocity is:
velocity = displacement / time
where displacement refers to the change in position or distance traveled, and time refers to the duration of the displacement.
For example, let’s say an object travels a distance of 100 meters in 10 seconds. The displacement would be 100 meters, and the time would be 10 seconds. Using the formula, we can calculate the velocity:
velocity = 100 meters / 10 seconds
= 10 meters per second
So, the object’s velocity is 10 meters per second.
Remember that velocity includes direction. If an object is moving forward, the velocity value will be positive. However, if it is moving backward or in the opposite direction, the velocity value will be negative.
It is also important to note that velocity can change over time due to acceleration. Acceleration refers to the change in velocity per unit time and can be either positive or negative. If an object’s velocity is increasing, it has positive acceleration. Conversely, if the velocity is decreasing, it has negative acceleration.
In summary, velocity is the rate of change of an object’s position or displacement over time and includes both magnitude and direction. It can be calculated by dividing the displacement by the time elapsed.
