<p>= area under a speed time graph Velocity-time graph problems On the graph below, indicate when the object is accelerating, elerating and maintaining a constant velocity Velocity-time graph Question: Consider the motion of the object whose velocity-time graph is given in the diagramWhat is the acceleration of the object between times and? Give the units of your answer. v(m/s) This yellow area is the same as the pink area. time graphs corresponding to the following descriptions of the motion of an object. Time (t seconds) (a) Usestrips  WorksheetVelocity-Time Graphs. Any point on such a graph will have coordinates (t,v), in which v is the velocity (a) Use the graph to estimate the speed of the car afterseconds. It then travels at a constant speed for a furtherseconds The object moves in the negative direction atm/s fors then in the positive direction atm/s forss then continues atm/s for then last secondb) The area under the graph from t =s to t =s is (2 s)(2 m/s) =mc) The area under the graph from t =s to t =s is =m (b) Use the graph to estimate the v(m/s) The area of the triangle is exactly the same as the area of the rectangle with a speed exactly half way between the two values, u & vAverage velocity. Sketch velocity vs. v ms—I The displacement of the body from t —FigO tot = the velocity-time graph of a car forseconds. (a)(a) Work out the average acceleration during theseconds. 2 Velocity-Time Graphs Example Questions. Fig. QuestionA ball is placed at rest at the top of a hill. The object is moving away from the  ×+2××= [1] Division of graph into triangles =m [1] Area under graph 5(b) Underestimate as more of the curve is above the line used for the estimate [1]  Figure The gradient of a displacement-time graph is velocityVelocity-time graphs. It then elerates at a constant rate of m/s ^2 forseconds. I is the velocity-time graph for the motion of a body. It travels with constant acceleration for the firstsecond and reaches a speed ofm/s. Time (seconds) (a) Use the graph to find the sprinter’s acceleration betweenandseconds. (b) Use the graph to find the acceleration of the car betweenandsecondsThe velocity-time graph below shows the run of a sprinter. The velocity of the body is v ms—I at time t seconds.</p></translate>
