When the motion of an object is shown by a straight line on a distance vs time graph the slope of the line is the?
The slope of a distance versus time graph is velocity. This is shown at two points. Instantaneous velocity at any point is the slope of the tangent at that point.
What does a straight line represent on a distance vs time graph?
‘Straight lines’ on a distance-time graph tell us that the object is travelling at a constant speed. Note that you can think of a stationary object (not moving) as travelling at a constant speed of 0 m/s. ‘Curved lines’ on a distance time graph indicate that the speed is changing.
What does it mean when there is a straight line on a velocity-time 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 negative slope on a distance versus time graph represent?
In position and time graphs, the slope of line indicates the velocity. Therefore negative slope of a position-time graph actually indicates negative velocity. Negative velocity is defined as the velocity of the object moving in an opposite direction.
When the motion of an object is shown by a straight line?
Motion with Constant Velocity: When an object is moving with constant velocity, it does not change direction nor speed and therefore is represented as a straight line when graphed as distance over time. You can also obtain an object’s velocity if you know its trace over time.
When an object is in motion its?
An object is in motion if it changes position relative to a reference point. Objects that are fixed relative to Earth – such as a building, a tree, or a sign – make good reference points.
How do you describe motion on a distance time graph?
If an object moves along a straight line, the distance travelled can be represented by a distance-time graph. 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.
What does a curved line on a graph mean physics?
If a position graph is curved, the slope will be changing, which also means the velocity is changing. Changing velocity implies acceleration. So, curvature in a graph means the object is accelerating, changing velocity/slope.
What does straight line mean in physics?
What is Motion in a Straight Line? If an object changes its position with respect to its surroundings with time, then it is called in motion. Motion in a straight line is nothing but linear motion. As the name suggests, it’s in a particular straight line, thus it can be said that it uses only one dimension.
What does a straight line represent?
A straight line is a curve such that every point on the line segment joining any two points on it lies on it. If a point moves on a plane in a given direction then its locus is called a straight line and the equation of its locus is called the equation of the straight line.
When the slope of an object is negative?
time graph reveals pertinent information about an object’s velocity. For example, a small slope means a small velocity; a negative slope means a negative velocity; a constant slope (straight line) means a constant velocity; a changing slope (curved line) means a changing velocity.
When the slope of an object is negative it indicates that the object is moving?
An object moving in the negative direction with positive acceleration is slowing down (since the a vector is in the opposite direction as the motion). So on a p-t graph, this object will be represented by a line which slopes downwards (- velocity) and levels off or becomes more horizontal over time (slowing down). 32.
What does the slope of a distance versus-time graph show?
The slope of a distance versus time graph provides the instantaneous speed of an object. If data from this graph is then used to construct a speed versus time graph, the slope of that graph would provide the instantaneous acceleration. What variables would be used to show motion of an object on a graph?
What happens when an object is not moving on the distance time graph?
If an object is not moving, the distance-time graph results in a horizontal line which shows that the object is at rest.
What does a straight line on a distance graph mean?
Ans. A straight line on a distance time graph denotes that an object is moving with a constant speed. You can also consider a non-moving stationary object also as a body progressing at a constant speed. Remember that, this graph, generally, does not have a line sloping downwards as every object with motion is “increasing” its length with time.
Which is greater the speed of the graph or the distance?
The steepness of the slope of the graph gives the speed. If the slope is greater (i.e., if the slope is steeper as in line OA of above time and distance graph, the speed is greater than the speed shown by line AB because its slope is flatter).
