The figure above shows the speed time graph (t, v) of a train travelling along a straight horizontal track between two stations which are km apart. The train starts from rest at the first station and accelerates uniformly for m, reaching a speed of 36 ms− decelerates uniformly at ms− This resource is a complete lesson that covers Displacement & Velocity-Time Graphs for the OCR A Level Physics A course. However, it is useful for other exam boards too. -Velocity–time graphs; acceleration is gradient; displacement is area under graph. -A full presentation including example questions with worked solutions Distance and Displacement from a velocity vs. time graph. Ask Question Asked 6 years ago. Modified 6 years ago. Viewed 7k times -1 Missing: studio When the displacement of the particle is plotted as a function of time, it is displacement - time graph. As v = ds/dt, the slope of the s - t graph at any instant gives the velocity of the particle at that instant. In Fig. the particle at time t1, has a positive velocity, at time t2, has zero velocity and at time t3, has negative velocity 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) Missing: studio We move to the left by six. So in the case of displacement, you subtract the six, and you have a net displacement of plus two. But distance, the total path traveled, you have the eight to the right, and then six to the left. Which gives you a total path traveled of Let's do one more example here Note that this is the same operation we did in one dimension, but now the vectors are in three-dimensional space. Figure 2: The displacement Δr = r (t2) −r (t1) Δ r → = r → (t 2) − r → (t 1) is the vector from P1 P 1 to P2 P 2. The following examples illustrate the concept of displacement in multiple dimensions Worked example. A swing is pulled 5 cm and then [HOST] variation of the horizontal displacement x of the swing with time t is shown on the graph below. The swing exhibits simple harmonic [HOST] data from the graph to determine at what time the velocity of the swing is first at its maximum. Step 1: The velocity is at its maximum when

Remember, acceleration is the same as gradient, and acceleration = velocity change ÷ time. Look at the graph. The acceleration of the vehicle in the first 10 seconds is This video is created by [HOST] More videos are available at [HOST] Well actually I want to plot displacement over time because that will be more interesting. We know that displacement is the same thing as average velocity times change in time (displacement=Vavg*(t1-t2)). Right now we have something in terms of time, distance, and average velocity but not in terms of initial velocity and acceleration Maximum velocity is 5 ms –1 Distance 0 to 3 s = ½ × 3 × (= ) B1 Distance 3 to 5s = −∫5(− +) 3 t2 4t −15 dt M1 For usingv = 0 + at For finding the value of t when dv/dt = 0 For evaluating v(10) as vmax (the graph excludes the possibility of v(10) as vmin) Attempt to integrate and use limits Distance = ± m A1 Speed, velocity, scalars and vectors; Acceleration; Distance-time graphs of motion; Velocity-time graphs of motion; Completing calculations on curves Displacement-time graph: average and instantaneous velocity.

The displacement, velocity and acceleration of a particle performing linear SHM are periodic (harmonic) functions of time. For a particle starting from an extreme position, the x-t and a-t graphs are cosine curves; the v-t graph is a sine curve Q5. Sketch a displacement-time graph for a ball thrown vertically upwards with an initial velocity +Ö5g ms-1, Sketch a velocity-time graph to show this motion. The ball is modelled as a particle moving freely under the influence of gravity alone. c) Explain two additional factors which may be taken into account in a refinement of the above Part A: Average velocity is defined to be the displacement per time. v a v g = Δ x Δ t = 0 m − 8 m 6 s − 0 s = − 8 m 6 s (Use definition of average velocity.) v a v g = − 4 3 m s (Calculate and celebrate.) Part B: Average speed is So, in that case Distance $$\ne $$ Displacement Example: Let the velocity-time graph be as shown below: Now Displacment$$=$$ Area under the curve $$=\cfrac{1}{2}\times 5\times 2-\cfrac{1}{2}\times 5\times 2+\cfrac{1}{2}\times 5\times 2=5m$$ Whereas Distance $$=\cfrac{1}{2}\times 5\times 2+\cfrac{1}{2}\times 5\times 2+\cfrac{1}{2}\times 5\times The Velocity-Time Graphs: Displacement Calculations Interactive Video Tutorial describes the significance of area on a velocity-time graph.
