In physics, tangent refers to a line that touches but does not cross or intersect with another curve at one specific point.
Slope represents how steep or gradual a line or curve is at a particular point, and it can be calculated using tangent.
Derivative: In calculus, the derivative of a function represents its rate of change at any given point, often calculated using tangent lines.
Instantaneous velocity is the velocity of an object at a specific instant in time, which can be determined by finding the slope (tangent) of its position-time graph.
