The Velocity-Time Graphs: Displacement Calculations Video Tutorial describes the significance of area on a velocity-time graph. Details about how to calculate the area between the line and the time axis are explained and modeled through numerous examples.
Displacement-time graphs show the displacement of an object from a fixed origin as it moves in a straight line. They show displacement (on the vertical axis) against time (on the horizontal axis) Displacement-time graphs can go below the horizontal axis whereas distance-time graphs can not.
How would you calculate the displacement of an object that decreases velocity then remains at a constant velocity? Especially if the graph crosses to underneath the time axis to negative velocity?
In the linear portion of the stress-strain diagram, the tress is proportional to strain and is given by $\sigma = E \varepsilon$ since $\sigma = P / A$ and $\varepsilon = \delta / L$, then $\dfrac {P} {A} = E \dfrac {\delta} {L}$ $\delta = \dfrac {PL} {AE} = \dfrac {\sigma L} {E}$ To use this formula, the load must be axial, the bar must have a ...
Displacement can be calculated by measuring the final distance away from a point, and then subtracting the initial distance. Displacement is key when determining velocity (which is also a vector). Velocity = displacement/time whereas speed is distance/time.
Calculate the total displacement of the object, whose motion is represented by the velocity-time graph below. The displacement can be found by calculating the total area of the shaded sections...
Displacement-time graphs show the changing position of an object in motion. They also show whether an object is moving forwards (positive displacement) or backwards (negative displacement) Velocity = Gradient of a displacement-time graph. The greater the slope, the greater the velocity.
