What is the explanation for the area under the curve?
In statistics you can find the area under a curve to establish what to expect between two input numbers. If there is a lot of area under the curve the graph is tall and there is a higher probability of things occurring there than when the graph is low.
How do you find distance in a speed time graph?
The distance from the origin at time t, in the direction of motion, is the area under the graph between time 0 and time t. In a simple speed-time graph the area may be calculated using simple formulae for the areas of triangles, rectangles, trapeziums. In more complicated cases you will need to integrate for the area under the speed-time curve. And in seriously complex cases, you will have to use numerical estimation for the area.
How do you find acceleration using a speed-time graph?
true
How can you find the instantaneous acceleration of an object whose curve on the velocity time graph is a straight line?
It is the gradient (slope) of the line.
How do you find average speed on a graph?
Assuming it's a graph of speed vs time, then between 2 times, the average is the distance (= area under the graph between those times) divided by the time difference.
How do you find the slope of a graph if it is a curve?
You find the slope of the tangent to the curve at the point of interest.
How do you find maximum speed in a time position graph?
To find the maximum speed in a time-position graph, you would need to locate the steepest slope or the point with the highest gradient on the graph. This slope represents the highest rate of change in position over time, which corresponds to the maximum speed.
How do you find retardation if speed and stopping time is given?
Retardation can be found by dividing the change in velocity (initial speed minus final speed) by the stopping time. Retardation represents the rate at which an object slows down.
How do you find acceleration of a speed time graph?
To find acceleration from a speed-time graph, you need to calculate the slope of the speed-time graph. The slope at any point on the speed-time graph represents the acceleration at that specific time. If the speed-time graph is linear, then the acceleration will be constant. If the speed-time graph is curved, you can find the acceleration by calculating the slope of the tangent line at a specific point.
How can you get the speed of an object from its distance-time graph?
You can find the speed of an object from its distance-time graph by calculating the slope of the graph at a specific point. The slope represents the object's velocity at that particular moment. By determining the slope, you can find the speed of the object at that point on the graph.
What is the explanation for the area under the curve?
In statistics you can find the area under a curve to establish what to expect between two input numbers. If there is a lot of area under the curve the graph is tall and there is a higher probability of things occurring there than when the graph is low.
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.
How do you find retardation if speed of a bus and its stopping time interval is given?
Reteradation will be half of acceleration
How do you find the average speed from a velocity time graph?
To find the average speed from a velocity-time graph, calculate the total distance traveled and divide it by the total time taken. This will give you the average speed. Alternatively, you can find the slope of the secant line that connects the initial and final points on the graph to determine the average speed.
How do you solve an acceleration vs time graph problem?
To solve a problem involving an acceleration vs. time graph, you can find the velocity of the object at different time intervals by calculating the area under the graph. To find the displacement of the object, you can integrate the acceleration function over the given time interval to get the velocity function, then integrate the velocity function to get the displacement function.
How do you find distance in a speed time graph?
The distance from the origin at time t, in the direction of motion, is the area under the graph between time 0 and time t. In a simple speed-time graph the area may be calculated using simple formulae for the areas of triangles, rectangles, trapeziums. In more complicated cases you will need to integrate for the area under the speed-time curve. And in seriously complex cases, you will have to use numerical estimation for the area.
How do you determine the speed of an object by looking at a graph?
To determine the speed of an object from a graph, you can calculate the average speed by finding the slope of the line connecting two points on the graph. The steeper the slope, the higher the speed. Alternatively, you can also find the instantaneous speed by looking at the slope of the tangent line at a specific point on the graph.
