Tangential velocity and average velocity are both concepts used to describe the motion of objects, but they refer to different aspects of motion.
Tangential Velocity: Tangential velocity is a measure of how fast an object is moving along its curved path at a particular instant. It is the velocity of an object tangent to its path at any given point. Tangential velocity is a vector quantity because it has both magnitude (speed) and direction, and it represents the instantaneous velocity of an object at a specific moment in time.
Average Velocity: Average velocity, on the other hand, is a measure of displacement per unit of time. It is calculated by dividing the total displacement of an object by the total time taken. Average velocity is also a vector quantity because it includes both magnitude (speed) and direction. Unlike tangential velocity, which describes the instantaneous velocity, average velocity provides information about the overall motion of an object over a given time interval.
To summarize, tangential velocity focuses on the instantaneous velocity along a curved path, while average velocity represents the overall displacement per unit of time over a given interval.
