Sep 12, 2022 · However, we can calculate the instantaneous speed from the magnitude of the instantaneous velocity: \[Instantaneous\; speed = |v(t)| \ldotp \label{3.6}\] If a particle is moving along the x-axis at +7.0 m/s and another particle is moving along the same axis at −7.0 m/s, they have different velocities, but both have the same speed of 7.0 m/s.
The three steps must have equal displacement. The displacement of the third step is larger than the displacement of the first two. The average velocity must add up to zero. The distance and average velocity must add up to zero. What can we learn about motion by looking at velocity vs. time graphs?
Instantaneous speed is found by taking the absolute value of instantaneous velocity, and it is always positive. Average speed is total distance traveled divided by elapsed time. The slope of a position-versus-time graph at a specific time gives instantaneous velocity at that time.
The instantaneous velocity is shown at time t 0 t 0, which happens to be at the maximum of the position function. The slope of the position graph is zero at this point, and thus the instantaneous velocity is zero.
Learn how to find an object’s instantaneous speed or velocity in three ways - by using calculus, by looking at the slope of a given point on a graph of an object’s rate vs. time, or by using kinematic formulas if the object’s acceleration is constant.
