Learning intentions:
what a horizontal line on a velocity-time graph tells us
how to tell from a velocity-time graph if an object is accelerating or decelerating
what the area under a velocity-time graph tells us
Task
Use the car chase to time when the car gets to those speeds.
Change speed to velocity and plot a graph of velocity against time. Use graph paper and a pencil.
Calculate the acceleration at each stage using the equation. Acceleration = final velocity - starting velocity time
The distance travelled is the area under the graph. How far did the car go in that time.
The video comes in two parts.
