what is the nature of speed time graph for uniform motion?

For uniform motion, the distance-time graph is a straight line parallel to the time axis as speed will be constant.

A horizontal line on a speed-time graph represents a constant speed. A sloping line on a speed-time graph represents an acceleration. The sloping line shows that the speed of the object is changing. The object is either speeding up or slowing down.

If an object covers equal distance in equal interval of time, then time speed graph of an object is a straight line parallel to time axis then body is moving with a uniform speed. Non-uniform speed : If the speed of a body is changing with respect to time it is moving with a non-uniform speed.

The term constant acceleration means the acceleration is uniform that is it has a regular rate of change of velocity wrt time i.e. the incremental change in velocity is uniformly fixed wrt time; hence the reason why it appears a straight line on a velocity time graph. The motion is known as “uniform acceleration”.

The area under a speed-time graph represents the distance travelled. This is a velocity time graph of an object moving in a straight line due North. The displacement of this object is the area of the velocity time graph.

Uniform Motion: Definition: This type of motion is defined as the motion of an object in which the object travels in a straight line and its velocity remains constant along that line as it covers equal distances in equal intervals of time, irrespective of the duration of the time.

Ex: A car moving in a speed of 60kmph for a specific period of time is said to be in uniform velocity. Ex: A car takes 10 seconds to reach from 0 to 30 kmph requires the same 10 seconds to reach from 30 to 60 kmph is said to be in uniform acceleration.

time graph to determine velocity, we can use a velocity vs. time graph to determine position. We know that v = d/t. If we use a little algebra to re-arrange the equation, we see that d = v × t.

Slope on a position time graph is velocity. What is the acceleration of the object at t = 7.0 s? Zero- if the velocity is linear on a position time graph, the acceleration is zero.

Velocity time graph is the graph of velocity against time which shows how the velocity changes with respect to time. Slope of Displacement-time graph: The slope of a velocity-time graph would give the acceleration of the object.

time graph plots acceleration values on the y-axis, and time values on the x-axis. ... time graph, the slope at that point (derivative) will always be equal to the acceleration at that time. So, if at some moment your acceleration is positive, then at that moment your velocity will be increasing.

The position-time graph describes the motion of an object over a period of time. Time in seconds is conventionally plotted on the x-axis and the position of the object in meters is plotted along the y-axis. The slope of the position-time graph reveals important information about the velocity of the object.

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.

In non uniform motion, movement of a body is along the straight line with variable speed. In uniform motion, body covers equal distance in equal interval of time. In this type of motion, the body does not cover the equal distance in equal interval of time.

Average speed is distance divided by time. Velocity is speed in a given direction. Acceleration is change in velocity divided by time. Movement can be shown in distance-time and velocity-time graphs.

Graph Values For example, a continuous graph of velocity over a given unit of time can be evaluated to determine the overall distance traveled. Conversely, a discrete graph, when evaluated as a series or sequence, will return the value of velocity that the system tends to as time moves on.

For a body moving with constant velocity, the displacement time graph is a straight line inclined at any angle from the time axis.
