What does a diagonal line mean on a motion graph?

On a velocity-time graph a horizontal (flat) line indicates the object is travelling at a constant speed. A straight diagonal line indicates the object’s velocity is changing.

What does a sloping line downwards indicate on a motion graph?

Summary: A speed – time graph shows us how the speed of a moving object changes with time. The steeper the graph, the greater the acceleration. A horizontal line means the object is moving at a constant speed. A downward sloping line means the object is slowing down.

What does a slanted line mean on a distance-time graph?

A sloping line on a distance-time graph shows that the object is moving. 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.

What does a diagonal slope mean?

Lines that fall from left to right have a negative slope. So a diagonal line to the right ( / ) would have a positive slope. A diagonal line to the left ( \ ) would have a negative slope. A vertical line ( | )has an undefined slope and a horizontal line ( —- ) has a slope of 0.

What does a downwards slope on a velocity-time graph show?

In a velocity-time graph, acceleration is represented by the slope of the graph line. If the line slopes downward, like the line between 7 and 10 seconds, velocity is decreasing and acceleration is negative.

What does slope of position time graph indicate?

The slope of position time graph represents speed or velocity of the object or particle.

What is meant by slope of a graph?

In mathematics, the slope or gradient of a line is a number that describes both the direction and the steepness of the line. Slope is calculated by finding the ratio of the “vertical change” to the “horizontal change” between (any) two distinct points on a line.

What does the diagonal line mean in science?

A diagonal is a line joining two vertices in a polygon that are not on the same edge. …

What does slope of displacement time graph represent?

A sloping line on a displacement-time graph shows that the object is moving. In a displacement-time graph, the slope or gradient of the line, is equal to the velocity of the object.

What does the shape of the line on the graph represent?

Thus the shape of the line on the graph (straight, curving, steeply sloped, mildly sloped, etc.) is descriptive of the object’s motion. In this part of the lesson, we will examine how the actual slope value of any straight line on a graph is the velocity of the object. Consider a car moving with a constant velocity of +10 m/s for 5 seconds.

What does a horizontal line on a velocity-time graph indicate?

On a velocity-time graph a horizontal (flat) line indicates the object is travelling at a constant speed. A straight diagonal line indicates the object’s velocity is changing. In the graph on the left, the line sloping upwards shows the object is accelerating and the line sloping downwards in this case towards v = 0, shows it is decelerating.

What is the meaning of slope for a p-t graph?

The Meaning of Slope for a p-t Graph. Both of these examples reveal an important principle. The principle is that the slope of the line on a position-time graph is equal to the velocity of the object. If the object is moving with a velocity of +4 m/s, then the slope of the line will be +4 m/s.

When is the slope of the line equal to the acceleration?

In both instances above – the constant velocity motion and the changing velocity motion, the slope of the line was equal to the acceleration. As a last illustration, we will examine a more complex case – a two-stage motion.
