How is speed and acceleration represented on a graph?
Speed is represented by the slope of a distance-time graph, where steeper slopes indicate faster speed. Acceleration is represented by the slope of a speed-time graph, where a steeper slope indicates a greater acceleration.
How is constant speed represented on a time graph?
On a time graph, constant speed is represented by a straight line with a constant slope. The slope of the line indicates the speed of the object – the steeper the slope, the faster the speed, and the shallower the slope, the slower the speed.
Does the slope of a speed-versus-time graph represents acceleration?
No, the slope of a speed-versus-time graph represents the rate of change of speed, not acceleration. Acceleration is represented by the slope of a velocity-versus-time graph.
What does straight line on a distance time graph tell you about the speed of an object?
It tells you that the speed of the object is not changing. The speed is represented by the slope in a distance vs. time graph, if slope doesn't change, speed doesn't.
How is constant speed represented on a distance time motion graph?
On a distance-time graph, a constant speed is represented by a straight, diagonal line with a constant slope. This slope indicates that the object is covering the same distance for each unit of time, meaning its speed is consistent throughout the motion.
How do you calculate average speed with speed-time graph?
To calculate average speed using a speed-time graph, first identify the total distance traveled and the total time taken. The area under the speed-time curve represents the distance, while the total time is represented on the x-axis. Use the formula: average speed = total distance / total time. This gives you the average speed over the entire duration represented in the graph.
Can initial speed be obtained from speed-time graph of a body?
Yes, the initial speed of a body can be obtained from its speed-time graph. The initial speed corresponds to the value of the speed at time ( t = 0 ), which is represented by the y-coordinate of the point where the graph intersects the y-axis. If the graph starts above the origin, that value indicates the body's initial speed. If it starts at the origin, the initial speed is zero.
Will The slope of the line on a speed-time graph tells the speed?
No, the slope of the line on a speed-time graph does not represent speed; rather, it indicates acceleration. A horizontal line indicates constant speed, while a sloped line shows changing speed. The speed itself is represented by the vertical value on the graph at any given point.
What is represented by the area under the slope line on a speed time graph?
That's the distance covered.
What relationship could be represented by a graph with a negative slope?
something which decreases over time e.g. speed of a car when the brakes are applied. Time on the x-axis and speed on the y-axis of the graph
What is the physical quantity measured under a speed time graph?
The physical quantity measured under a speed-time graph is acceleration. This is because acceleration is represented by the gradient of the graph, where a steeper gradient indicates a higher acceleration.
Is The slope on a position-time graph is representative of the acceleration of the object?
No. Slope of position/time graph is speed, or magnitude of velocity.Slope of speed/time graph is magnitude of acceleration.
