How can you obtain the average velocity from a displacement time graph?
-- Pick two points on the graph. -- Find the difference in time between the two points. -- Find the difference in displacement between the same two points. -- (Difference in displacement) divided by (difference in time) is the average Speed . You can't tell anything about velocity from the graph except its magnitude, because the graph displays no information regarding the direction of motion.
How can you tell the difference between a speed and a velocity graph?
Very simply . . . you're not likely to ever see a velocity graph. At least notuntil you get into advanced engineering or science.Velocity is speed and its direction . . . more information than can be displayedon a simple graph.
What is an example of the difference between speed and velocity?
Speed is what it is: speed. Velocity is speed in a given direction, a vector quantity.
What is the nature of velocity time graph of a body moving with uniform retardation?
A body moving at a uniform speed may have a uniform velocity, or its velocity could be changing. How could that be? Let's look. The difference between speed and velocity is that velocity is speed.
What is speed the difference Between speed and velocity?
Speed is just a number; velocity includes information about the direction. In physical terms, speed is a scalar, whereas velocity is a vector.
Is Average velocity the slope of the line tangent to the curve on a velocity-time graph at a specific instant of time?
No. What you've described is instantaneous acceleration. To lift the average speed from a graph, you need a graph of distance-time. Pick two points in time, and find the distance at both those times. The average speed over that time interval is (difference between the distances at the beginning and end) divided by (difference between the two times). If you're just going for the average, then it doesn't matter what happened during the interval, only the values at the end-points. The slope of the line tangent to the curve on your distance-time graph is the instantaneous speed at that point in time. We're saying "speed" in this discussion because there's actually no such thing as a graph of velocity. No simple thing anyway. Velocity is a vector, whose magnitude is speed and which includes a direction. It's easy to graph speed vs time, but not that easy to graph direction vs time. So all the graph shows is speed.
What is the difference is between speed and velocity?
Speed is just a number; velocity includes information about the direction. In physical terms, speed is a scalar, whereas velocity is a vector.
The distance between speed and velocity is that velocity includes?
Velocity includes direction. And it's the 'difference', not the 'distance'.
What is the difference between speed velocity acceleration?
Speed is the rate of change in distance, whereas velocity is speed and direction of travel. Acceleration is the change in velocity (including direction).
What factor is the difference between speed and velocity?
Speed is exactly like velocity, except velocity has a fixed direction. So speed would be 50mph, whereas velocity would be 50mph NE
How are speed and velocity related and what is the key difference between the two?
Speed and velocity are both measures of how fast an object is moving. The key difference between the two is that velocity includes direction, while speed does not. Velocity is a vector quantity, meaning it has both magnitude (speed) and direction, while speed is a scalar quantity, only having magnitude.
What is the difference between a speed vs time graph and a distance vs time graph?
The dependent variable.
