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 the slope of a distance-time graph gives?
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.
What does the slope of a distance vs time line graph tell you?
The slope of a distance-time graph
represents speed
. The steeper the slope is, the faster the speed. Average speed can be calculated from a distance-time graph as the change in distance divided by the corresponding change in time.
What does slope of graph represent?
The slope of a position graph represents
the velocity of the object
. So the value of the slope at a particular time represents the velocity of the object at that instant.
When the slope of a line in a position versus time graph is positive what does that describe?
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 positive, then the slope is positive (i.e., moving upwards and to the right).
Why does the slope of a position-time graph represents velocity?
The slope of a position-time graph represents velocity. The steeper the slope is,
the faster the motion is changing
. Average velocity can be calculated from a position-time graph as the change in position divided by the corresponding change in time.
What type of motion is occurring when the slope of a position vs time graph is zero?
The type of motion occurring when the slope of a distance vs. time graph is zero is
the object being measured was held at a single position away from the sensor
.
What does the slope and area of velocity-time graph represents give explanation for obtained answer?
-As the slope of a velocity-time graph represents
the acceleration of the body
, the area under the curve represents the displacement or the distance travelled by the body with the applied velocity and time.
What does the slope of velocity-time graph?
The slope in the velocity-time graph represents
the acceleration
.
What type of motion is occurring when the slope is changing?
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
.
What does the slope of a velocity graph represent express it mathematically?
Determining the Slope on a v-t Graph. It was learned earlier in Lesson 4 that the slope of the line on a velocity versus time graph is
equal to the acceleration of the object
. … If the object is moving with an acceleration of -8 m/s/s, then the slope of the line will be -8 m/s/s.
How is changing velocity displayed in terms of slope?
If
the acceleration is positive
, then the line is an upward sloping line (i.e., the slope is positive). If the acceleration is negative, then the velocity-time graph is a downward sloping line (i.e., the slope is negative). If the acceleration is great, then the line slopes up steeply (i.e., the slope is great).
What type of motion is occurring when the slope of a position vs time graph is changing test your answer to this question using the motion detector?
A: When the slope of a position vs. time graph is changing this means that the subject is
changing their direction from walking ether walking towards the sensor or walking away from the sensor creating a change in the graph or a spike in it
.
What does it mean when the slope of a position-time graph is zero?
In a position-time graph,
the velocity of the moving object
is represented by the slope, or steepness, of the graph line. If the graph line is horizontal, like the line after time = 5 seconds in Graph 2 in the Figure below, then the slope is zero and so is the velocity. The position of the object is not changing.
How do the lines on the velocity-time graph differ for moving towards the motion detector compared to moving away from the motion detector?
How do the lines on the velocity-time graph differ for moving towards the motion detector compared to moving away from the motion detector? a.
When moving towards the detector, the line slopes upward
; when moving away from the detector, the line slopes downward.
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 type of motion is occurring when the slope of the graph velocity vs time is positive?
Note that a motion described as
a changing
, positive velocity results in a sloped line when plotted as a velocity-time graph. The slope of the line is positive, corresponding to the positive acceleration.
What is motion short answer?
Motion is
change of location
or position of an object with respect to time. Change in motion is the result of an applied force. Motion is typically described in terms of velocity also seen as speed, acceleration, displacement, and time.
What is the physical meaning of the slope physics?
Slope is
the change in the y-coordinate with a unit change in x coordinate
. ( means y changes by p units for a unit change in x) ( represents change) When the value of y coordinate increases with an increase in x, we say the graph has a positive slope. ( p has a positive value)
How do you explain motion to a child?
In science, motion is a change in position compared to a place or an object that is not moving. The place or object that is not moving is called the frame of reference. Motion is a kind of puzzle because every object in the universe is in motion. This means that no frame of reference is correct in every situation.
How many types of motion are there in physics?
In the world of mechanics, there are
four basic
types of motion. These four are rotary, oscillating, linear and reciprocating.
How do you find the slope on a graph in physics?
Pick two points on the line and determine their coordinates. Determine the difference in y-coordinates of these two points (rise). Determine the difference in x-coordinates for these two points (run).
Divide the difference in y-coordinates
by the difference in x-coordinates (rise/run or slope).
What does a straight line mean on a velocity time graph?
On a velocity-time graph… straight lines imply
constant acceleration
. curved lines imply non-constant acceleration. an object undergoing constant acceleration traces a straight line.
What does a velocity time graph show that changes over time?
A velocity-time graph shows
changes in velocity of a moving object over time
. The slope of a velocity-time graph represents acceleration of the moving object.
Why distance is area under velocity time line?
The area under a speed-time graph is the distance. … This is because
speed and distance are scalars
. The area under a velocity-time graph is the displacement. Velocity can be negative if an object is moving backwards.
