Instantaneous velocity is the rate of change of an object's displacement at a specific moment in time. It is a measure of how fast an object is moving in a particular direction at a specific point in its motion.
Average velocity is calculated by dividing the total displacement of an object by the total time taken, while instantaneous velocity is calculated at a specific point in time by taking the derivative of the position-time graph.
To determine the instantaneous velocity from a graph, find two points on the graph that are very close together. Then, calculate the slope of the line connecting these two points. This slope represents the instantaneous velocity at that specific point on the graph.
Yes, instantaneous velocity can be negative. This means that the object is moving in the negative direction at that specific point in time. It is important to pay attention to the direction of the velocity when interpreting a graph.
Instantaneous velocity is typically measured in units of distance per time, such as meters per second or kilometers per hour. The specific unit used will depend on the units of the coordinates on the graph.
