Jan 23, 2009 · If you have the equation of the distance-time graph, you can take its derivative and that will give you a general equation for instanteneous velocity. For instance, if a particle's position is... Maybe. Then again, you might have had to slow down because of heavy traffic for a while, but later you were able to drive a bit faster. So, over the two hours your speed averaged out to 60 mph. This is called Average Velocity or Average Speed and it is a common example of using an average rate of change in our everyday lives.

      Find instantaneous acceleration at a specified time on a graph of velocity versus time. The importance of understanding acceleration spans our day-to-day experience, as well as the vast reaches of outer space and the tiny world of subatomic physics. Rates of change and the slope of a curve . To see another way in which the derivative appears, let's go back to our earlier discussion about making measurements. Recall that we looked at a graph that describes the result of some scientific observation (the measurement of the value of the variable y at different times t).

      find the average velocity from t = 3 to t = 5. Solution: Use the average velocity formula! Therefore, the average velocity is 8 2) Find the velocity function and the acceleration function for the function s(t) = 2t 3 + 5t - 7. Solution: Use the instantaneous formulas. v(t) = s'(t) = 6t 2 + 5 a(t) = v'(t) = 12t How to Find the Tangent on a Graph in Excel. The tangent line for a graph at a given point is the best straight-line approximation for the graph at that spot. The slope of the tangent line reveals how steep the graph is rising or falling at that point. This type of information can be utilized on a business graph to ... The strain rate you get is an instantaneous value of strain rate - this will change during the testing, so you need to make the decision whether you take the average value, peak value, or some other.

To find this slope, we draw a tangent lineat the point of interest (in this case at 10 s). A tangent line is a line that touches a curve at only one point and is representative of the slope of the curve at that point.

      b.) Notice that each of these points is in the middle of a line segment on the graph. Because of this, the instantaneous velocity at these points is the same as the average velocity over the time intervals represented by each segment, so: v(t) = (x f - x i)/(t f - t i) v(1) = (3 - 0)/(2 - 0) = 3/2 = 1.5 m/s v(3) = (3 - 3)/(4 - 2) = 0/2 = 0 m/s You can find the previous tutorial post in this series here and the overview of the entire series here.

      If the graph of a Displacement-Time graph is curved or bent at any point, then motion is not constant and the object is undergoing acceleration. o Instantaneous Velocity: In a Displacement-Time Graph instantaneous velocity can be found by graphing the straight tangent line to the point where the instantaneous velocity to be found is located. To calculate the speed of an object from a graph representing constant velocity, all that is needed is to find the slope of the line; this would indicate the change in distance over the change in time. However, changing velocity it is not as straightforward. Since our velocity is constantly changing, we can estimate velocity in different ways.

      Amplitudes are expressed either as instantaneous values or mostly as peak values. Amplitude is the fluctuation or displacement of a wave from its mean value. With sound waves, it is the extent to which air particles are displaced, and this amplitude of sound or sound amplitude is experienced as the loudness of sound .
