Velocity-time graphs are essential for analyzing motion, where the y-axisrepresents velocity and the x-axis represents time. The slope of these graphs indicates acceleration, with steeper slopes signifying greater acceleration magnitudes. Average acceleration is calculated between two points, while ...

Velocity–time and speed–time graphs A change of velocity is called acceleration. Speeding up, slowing down and changing direction are all examples of acceleration. Fig. 9.2 shows how to interpret a velocity–time graph. Image A positive slope (gradient) means that the speed is increasing – ...
The velocity-time graph for the motion is shown above. Find (i) the distance travelled by the elevator, (ii) the acceleration during the first stage and the deceleration during the third stage. A cyclist starts from rest at point A and moves in a straight line with acceleration 0.5 m s...
A projectile is accelerating at a constant rate and increases its velocity from 10 m/s to 100 m/s. It does this in 100 meters. How long does this take? What are the equations that describe free-fall motion? How do you describe motion ...
Linear Acceleration Graphical Analysis of Acceleration : Velocity vs Time Graphs 1. For the v vs t graph shown below, (a) find the acceleration from t = 4 sec to t = 6 sec (-15/2 m/s 2 ) (b) find the acceleration from t = 8 sec to t = 10 sec (5 m/s 2 ) (c) circle...
Acceleration of the Velocity-Time graph In the given graph, a = (40-20)/(4-2) = 10 m/s2. For a particle it is equal to the slope of a velocity-time graph. Solved Example For You Q. A stone of mass m is thrown straight upward from the top of a multi-story building with an...
