  • So between zero and two seconds the object moved forward four meters. Between two and four seconds the object move backward four meters. And between four and six seconds the object moved backward another four meters, which means the total distance would be four meters plus four meters plus four meters, which would give you 12 meters of distance traveled. What does displacement mean? In physics, displacement is the difference in position. So if an object went forward then backward then forward again, the displacement could be represented with an arrow that points from the initial position all the way to the final position.

  • And that's why a formula for displacement can be thought of as the final position minus the initial position. This delta here represents the change in, which means final minus initial. The S. It's a vector, which means that the displacement is leftward or downward. The displacement can be negative. In other words, if you end up further left from where you started, your horizontal displacement's negative. And if you end up further down from where you started, your vertical displacement's negative.

  • In other words, if an object's taking a long winding path, you could find the average speed for the entire trip by taking the total distance for the entire trip and dividing by the time it took to travel that distance. Or to determine the instantaneous speed, you could look at an infinitesimally small distance and divide by the time it took to travel that infinitesimally small distance. The units for speed are meters per second. It is not a vector. And speed can only be positive or zero. Speed can never be negative. What's an example problem for speed look like? If you had this graph and you wanted to determine the average speed between zero and six seconds, you'd have to remember that average speed is the distance per time.

  • Or you could define the instantaneous velocity as the rate of displacement per time at a particular moment in time. So in other words, if an object took a long winding path and you wanted to determine the average velocity for the entire trip, you would take the displacement for the entire trip and divide by the time it took for that displacement. Or if you wanted the instantaneous velocity at a particular moment, you would take an infinitesimal displacement at that moment and divide by the time it took for that displacement. The units of velocity are meters per second.

  • And it is a vector. That means it can be negative. So if the velocity is directed leftward or downward, we typically consider the velocity to be a negative value. What's an example problem for velocity look like? If you had this graph and you wanted to determine the average velocity of the object between zero and six seconds, you'd have to remember that average velocity is the displacement per time. Since the object starts at zero meters and ends at six seconds at negative four meters, the displacement here is negative four. What does acceleration mean? Acceleration is the rate at which velocity changes. You could change your velocity by speeding up, slowing down, or by changing directions by turning. And it's good to remember that the acceleration of an object always points in the same direction as the net force on that object. So in other words, if you had a ball that had an initial velocity, vi, to the right and the ball speeds up to a larger v final to the right, there must have acceleration since the velocity changed.

  • How do you interpret a position versus time graph? Well, the value of the graph is giving you the position x. In other words, at some time, t, if you measure the value of the graph, on the vertical axis that value is giving you the position at that time, t. Why do we care about position versus time graphs? One reason we care is that the slope is gonna equal the velocity of the object. So if you can determine the slope, you can find the velocity. How do you find the slope? You find the region that you want to determine the slope in, and then you take the rise over the run, which is the change in x over the change in time for that portion of the graph. Since the rise over run here is displacement per time, the slope is equal to the velocity. Also, you can tell if there's acceleration on a position versus time graph depending on whether there's curvature or not.

  • Curvature that looks like a smiley face represents positive acceleration. And curvature that looks like a frowny face represents negative acceleration. Graphs that have constant slope would have constant velocity and zero acceleration. What would an example problem with position versus time graphs look like? Let's say we have this graph and we wanted to determine the instantaneous velocity at seven seconds. So we locate seven seconds. To find the velocity in this region we'll just find the slope in this region.

  • Since the slope is constant, we can find the slope between any two points in this region. Choosing six seconds and eight seconds will be the most convenient. So we'll use rise over run. The rise in this case would be the change in position. The run would be the change in time.
