Yes. If the graph is zero everywhere, then the object is stationary.

If the object is not stationary, then the graph must depart from zero.

Yes, the object is stationary when the velocity is zero, the point or points where the graph crosses the horizontal time axis

0If the curve is horizontal, then the speed is constant. If that horizontal graph lies on the x-axis, then the constant speed is zero, and the object is stationary.

If the line is a horizontal line coincident with the x (time) axis and at y = 0 (velocity) axis it is stationary

The object is stationary as its velocity is zero. The velocity of an object is the gradient of its distance-time graph and as the graph is a horizontal straight line, its gradient is zero. The object is stationary also as its distance from the time axis is not increasing.

Of course yes. An object is stationary when the graph is horizontal in a displacement-time graph.

A straight line that coincides with the time axis, i.e., its value is zero at any time.

Radial acceleration.The velocity time graph usually shows only radial velocity. That is the component of the velocity in the direction towards or away from the reference point (the origin). It does not record information on any transverse component.It may be easier to understand this argument in the context of a distance time graph. What is the graph of an object going around the origin at a constant speed? The distance is the same all the time and so the graph will be a flat line. But a flat line is supposed to mean the object is stationary! The problem is that it is moving but not in the radial direction - not towards or away from the origin. The distance time graph therefore does not register any movement and so the object is shown to be stationary.Radial acceleration.The velocity time graph usually shows only radial velocity.

Object will change distance time graph when speed is changing. Distance time graph don't changed indicate of the stationary.

On a velocity vs time graph, an object that is motionless is represented by a horizontal line through the zero velocity point.

The slope of the line of a distance versus time graph is the velocity of the object. If this is a constant, in other words the graph is a straight line, the object is not changing its velocity and so is not accelerating. If the object is accelerating, the velocity of the object will be changing, thus the graph will not be a straight line, but a curve - the amount of curvature (and direction) tells you how much the object is accelerating (and in what direction - velocity and acceleration are vector quantities with both magnitude and direction).

The velocity of the object at time = 0

from a velocity time graph you can find the distance the object travelled per second.

The rate of acceleration is a measure of the change of the velocity of an object with time. On a graph of velocity versus time, it is represented by the slope of the line so graphed. If velocity is changing in time, the object described is being accelerated. The greater the slope of the graph, the greater the change of velocity per unit of time and the greater the acceleration of that object. true

A negative slope on a velocity-time graph indicates a decreasing velocity over time, which means the object is slowing down. As time increases, the velocity decreases.

If the Object is falling at a constant velocity the shape of the graph would be linear. If the object is falling at a changing velocity (Accelerating) the shape of the graph would be exponential- "J' Shape.

The graph curves upward, because as time goes on, the speed of the object ... the magnitude of its velocity ... keeps growing.

A position time graph can show you velocity. As time changes, so does position, and the velocity of the object can be determined. For a speed time graph, you can derive acceleration. As time changes, so does velocity, and the acceleration of the object can be determined.If you are plotting velocity (speed) versus time, the slope is the acceleration.

this time is basically the instant when an object has a particular velocity(instantaneous velocity). so on the graph draw a line from the particular value of the velocity and then draw a vertical line on time axis to find the time for that velocity.

velocity is nothing but speed of a body in the given direction. suppose if body is moving with constant velocity then VT graph will be parallel to the X -axis, if not then the VT graph is not parallel to the X-axis it means then object is moving with different velocity or it has its dierection or both velocity and aswell as direction.

The slope of a velocity-versus-time graph represents the acceleration of the object.

The slope of velocity is the acceleration of the object and indirectly the force of the object given the its mass.

It represents the velocity of the object.

the velocity of the object

The slope of the graph at any point is the object's speed at that time. (Not velocity.)

Normally a position-time graph is actually a distance-time graph where the distance of an object is measured from a fixed point called the origin. The slope (gradient) of the graph is the radial velocity - or the component of the velocity in the radial direction - of the object. That is, the component of the object's velocity in the direction towards or away from the origin. Such a graph cannot be used to measure the component of the velocity at right angles to the radial direction. In particular, an object going around in a circle would appear t have no velocity since its distance from the origin remains constant.

A distance-time graph shows the movement of an object with respect to time. The average slope between any two points on the graph is equal to the average velocity of the object between those two points. The instantaneous slope (or derivative) at a point on the graph is equal to the instantaneous velocity of the object at that point.
