Velocity-time graphs are used to describe the motion of objects which are moving in a straight line. Let's see what one might look like. On the last page, the graph showed position (a vector quantity) plotted against time (a scalar quantity). As it falls, it decreases the same way, just from $0$ to $-20$ m/s (it becomes more negative because acceleration and velocity have the same direction). Re: time/speed graph. What is the shape of the acceleration vs time graph? I am thinking that because the relationship with distance and Electric Field strength is an inverse square, that the relationship with distance and Electric Force is also an inverse square. A person runs 12 metres in 2 seconds. Set the position, velocity, or acceleration and let the simulation move the man for you.

Record data into the data table. Students read this from the graph. Find Bob’s acceleration at time. time graph, multiplied by the mass. The principle is that the slope of the line on a velocity-time graph reveals useful information about the acceleration of the object. The graphs on the top of the next column represent the motion of an object along a line which is the positive position axis. A rocket, initially at rest, is fired vertically upward with an acceleration of 12. Answer the following questions using the velocity vs. I is the velocity-time graph for the motion.
