t graph during this hour. On v vs. t graphs, zero velocity lies on the x-axis where the y value is 0 km/hr. Distance from v vs. t graphs To find the distance traveled from a velocity versus time graph, we use a graphical interpretation of the equation d = vt. Consider the ...
Explain the relationships between instantaneous velocity, average velocity, instantaneous speed, average speed, displacement, and time. Calculate velocity and speed given initial position, initial time, final position, and final time. Derive a graph of velocity vs. time given a graph of position vs....
velocity case 2: speed-time graphs with constant acceleration when the acceleration is constant, and the initial speed of the particle is zero, the speed of the particle will increase linearly, as predicted by the equation: v = u + at since u = 0 v = at speed-time graph with constant...

Check carefully whether a graph is a speed-time graph or a distance-time graph. On true speed–time graphs, the speed has only positive values. On velocity–time graphs the velocity can be negative. Image Tachographs are instruments that are put in lorry cabs to check that the lorry ...
Time limit: 45 minutes.Score: Your score is equal to the number of correct answers (no deduction for incorrect answers). If there are tie scores, the entries will be compared, from the end of the test forward, until the tie is resolved. Thus, the answers to the last few questions may...
