Is distance-time graph always positive?
That is not a negative slope. A negative slope is when the y-axis value decreases with increasing x-axis value. The slope of a distance-time graph is always positive or flat, because your distance travelled can never decrease as time moves forwards.
Can the displacement time graph has a negative slope give reason?
Reason : When the speed of body decreases with time the position-time graph of the moving body has negative slope.
What graph has a negative slope?
line graph
Graphically, a negative slope means that as the line on the line graph moves from left to right, the line falls. We will learn that “price” and “quantity demanded” have a negative relationship; that is, consumers will purchase less when the price is higher.
What is the slope of a distance-time graph?
In a distance-time graph, the slope or gradient of the line is equal to the speed of the object. The steeper the line (and the greater the gradient) the faster the object is moving.
Can a distance graph be negative?
Can a distance-time graph have a negative slope? Nope. Distance is a non-directional quantity. During a motion, it can only either be kept unchanged or increased.
Is distance can be negative?
Distance cannot be negative, and never decreases. Distance is a scalar quantity, or a magnitude, whereas displacement is a vector quantity with both magnitude and direction. It can be negative, zero, or positive.
What does the slope of distance graph indicate?
The slope of the distance-time graph indicates speed. It is because the slope of a distance-time graph determines the speed of that body, so the steeper the slope greater will be the speed of the body.
How do you describe a distance time graph?
A distance-time graph shows how far an object has travelled in a given time. Distance is plotted on the Y-axis (left) and Time is plotted on the X-axis (bottom). A moving object is always ‘increasing’ its total length moved with time. ‘Curved lines’ on a distance time graph indicate that the speed is changing.
Can distance time graph be decreasing?
In a distance-time graph, the gradient of the line is equal to the speed of the object. The greater the gradient (and the steeper the line) the faster the object is moving….Distance-time graphs for accelerating objects – Higher.
| Section of graph | Gradient | Speed |
|---|---|---|
| C | Decreasing | Decreasing |
| D | Zero | Stationary (at rest) |
What does a positive slope on a distance time graph mean?
The principle is that the slope of the line on a position-time graph reveals useful information about the velocity of the object. If the velocity is changing, then the slope is changing (i.e., a curved line). If the velocity is positive, then the slope is positive (i.e., moving upwards and to the right).
