A velocity-time graph shows **the speed and direction an object travels over a specific period of time**. Velocity-time graphs are also called speed-time graphs. The vertical axis of a velocity-time graph is the velocity of the object.

Even so, what does no velocity look like on a graph?

If the graph is flat or horizontal, then the object is not moving, the **slope is zero**, and the velocity is zero. It is important that when you have a graph, there is a title, axes labels, and units.

Never mind, does a velocity-time graph show displacement? Calculate the total displacement of the object, whose motion is represented by the velocity-time graph below. The displacement can be found by calculating the **total area of the shaded sections between the line and the time axis**.

Not only, can you find acceleration from a velocity-time graph?

Acceleration is **determined by the slope of time-velocity graph**. If the time velocity graph is a straight line, acceleration remains constant. If the slope of the straight line is positive, positive acceleration occurs. If the slope of the straight line is negative, negative acceleration or retardation occurs.

What is significance of velocity-time graph?

Velocity-time graphs are used to **describe the motion of objects which are moving in a straight line**. They can be used to show acceleration and to work out displacement.

The area under the velocity-time graph represents **the distance travelled**. Velocity-time graph for a car moving with uniform acceleration is a straight line and the area of the graph gives the distance travelled during a time interval.

If velocity is 0 , that means **the object is not moving**, but with acceleration present, there is a force acting on the object. ... Velocity slows to a halt, but is subjected to an acceleration of 9.8 ms2 [down] .

The principle is that **the slope of the line on a** velocity-time graph reveals useful information about the acceleration of the object. If the acceleration is zero, then the slope is zero (i.e., a horizontal line). If the acceleration is positive, then the slope is positive (i.e., an upward sloping line).

Velocity versus time graphs represent changes which occur in an object's velocity with respect to time. The slope of the line is the acceleration (change in velocity divided by the change in time) of the object. The area under the line (between the line on the graph and the time axis) is the displacement of the object.

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.

If the acceleration is constant, it is possible to find acceleration without time if we have the initial and final velocity of the object as well as the amount of displacement. The **formula v2=u2+2as** where v is the final velocity, u is the initial velocity, a is the acceleration and s is the displacement is used.

Distance time graph that tells us how much distance you have travelled while the velocity time graph **tells you your acceleration**.

1) Area of the velocity time graph gives us displacement. 2) Slope of the velocity time graph gives acceleration. Advantages of Distance-time graph: 1) **It helps us to locate the position of the object.**

With no acceleration, the "velocity" is constant ... the **speed isn**'t changing and the direction isn't changing. A so-called "velocity/time" graph is really just a "speed/time" graph, because it doesn't show any information about the direction of motion. ... So the graph never gets any higher or lower.

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.

The area under the velocity-time graph represents **distance covered** and the slope of the velocity-time graph represents acceleration.

From speed-time graph of a body, we can calculate **acceleration of the body and the distance travelled by the body**.

Explanation: An object having zero velocity implies **that it is stationary at a particular location**. If we plot it on a velocity-time graph which represents velocity on the y -axis and time on the x -axis, it is represented by x -axis. Value of y (velocity), is 0 for all values of x (time).

For the most part velocity is not zero **if an object is accelerating**. ... If the velocity is constant however, the acceleration is zero (because the velocity isn't changing over time). Although at an instant in time it is possible to have zero velocity whilst accelerating.

Negative velocity and positive slope,: object is slowing down. Velocity-Time Graphs. If the V-T line has a negative slope, **the object is undergoing acceleration in the negative direction**.

Simply **subtract the x-values and the y-values to find the lengths**. Therefore, if we were to plug in the points of (x1, y1), and (x2, y2), then move the square over to the other side of the equation so that it becomes a square root, we'll get the formula for distance.

The distance travelled is the path taken by a body to get from an initial point to an end point in a given period of time, at a certain velocity. If the velocity is constant: **Distance = time * velocity.** d = v*t.

When a car moves faster, its velocity increases. ... When the car's velocity changes, the car is **accelerating**. Acceleration is a measure of the change in velocity during a period of time. An object accelerates when its velocity changes as a result of increasing speed, decreasing speed, or a change in direction.

Note that when the acceleration is negative — on the interval [0, 2) — that means that the velocity is decreasing. **When the acceleration is positive** — on the interval (2, 4] — the velocity is increasing.

Velocity vs. time graph shows **the variation of velocity with time**.

To find out something's speed (or velocity) after a certain amount of time, you **just multiply the acceleration of gravity by the amount of time since it was let go of**. So you get: velocity = -9.81 m/s^2 * time, or V = gt.

To solve for time, **divide the distance traveled by the rate**. For example, if Cole drives his car 45 km per hour and travels a total of 225 km, then he traveled for 225/45 = 5 hours.
