explain how acceleration and displacement are calculated velocity-time graph plzz ans it's urgent
Answers
Answer:
Acceleration = Final Velocity - Initial velocity
Time
Displacement = Total Distance travelled
Total time taken
Answer:
For velocity versus time graphs, the area bound by the line and the axes represents the displacement. The diagram below shows three different velocity-time graphs; the shaded regions between the line and the time-axis represent the displacement during the stated time interval.
The shaded area is representative of the displacement during from 0 seconds to 6 seconds. This area takes on the shape of a rectangle can be calculated using the appropriate equation.
The shaded area is representative of the displacement during from 0 seconds to 4 seconds. This area takes on the shape of a triangle can be calculated using the appropriate equation.
The shaded area is representative of the displacement during from 2 seconds to 5 seconds. This area takes on the shape of a trapezoid can be calculated using the appropriate equation.
The method used to find the area under a line on a velocity-time graph depends upon whether the section bound by the line and the axes is a rectangle, a triangle or a trapezoid. Area formulas for each shape are given below.
Rectangle Triangle Trapezoid
Area = b • h Area = ½ • b • h Area = ½ • b • (h1 + h2)
