2.2 Velocity-Time Graphs
Speedometer
Instantaneous Speed: The speed of an object at a specific moment in time, which can be determined from the slope of the tangent line to the curve at that point on a velocity-time graph.
Instantaneous Velocity: The vector quantity that specifies the speed of an object in a particular direction at a specific moment, also defined by the slope of the tangent line on a velocity-time graph.
Velocity-Time Graph: Visual representation of an object’s motion that shows how an object’s velocity varies over time
The slope tells us the rate of acceleration, indicating how quickly the velocity of the object is changing at that given moment.
Curves: acceleration is not fixed and is changing over time
Differential Calculus
The area under the curve represents the displacement of the object during that time interval, allowing us to quantify the distance traveled.
