A=m/s×s. ∴A=meter. Therefore, the area under the curve of the velocity time graph gives distance covered by the body. Note: The gradient of the curve in the distance time graph defines the velocity of the body.

The area enclosed by the velocity-time curve and the time axis represents the distance travelled by the body.

The area under an acceleration graph represents the change in velocity. In other words, the area under the acceleration graph for a certain time interval is equal to the change in velocity during that time interval.

What does the area under a velocity graph represent? The area under a velocity graph represents the displacement of the object. To see why, consider the following graph of motion that shows an object maintaining a constant velocity of 6 meters per second for a time of 5 seconds.

You can’t fully represent displacement by finding the area, since as a vector quantity, displacement also requires a direction. Finding the area only gives an amount, no direction. The area under the curve is the magnitude of the displacement, which is equal to the distance traveled (only for constant acceleration).

In a velocity-time graph, acceleration is represented by the slope, or steepness, of the graph line. If the line slopes upward, like the line between 0 and 4 seconds in the Figure above, velocity is increasing, so acceleration is positive.

An object which moves in the positive direction has a positive velocity. If the object is slowing down then its acceleration vector is directed in the opposite direction as its motion (in this case, a negative acceleration).

To find the displacement (position shift) from the velocity function, we just integrate the function. The negative areas below the x-axis subtract from the total displacement. To find the distance traveled we have to use absolute value.

The reason is simple. Speed is the time rate at which an object is moving along a path, while velocity is the rate and direction of an object’s movement. Put another way, speed is a scalar value, while velocity is a vector.

Velocity: Velocity is a physical vector quantity. It has a magnitude as well as direction….Speed & Velocity.

Velocity is the rate of change of position with respect to time, whereas acceleration is the rate of change of velocity. Both are vector quantities (and so also have a specified direction), but the units of velocity are meters per second while the units of acceleration are meters per second squared.

So whether its a car moving, a ball being dropped, or the earth moving around the sun, all of these things have a velocity!

Frequency: Velocity is the rate of motion, speed or action. An example of velocity is a car driving at 75 miles per hour. Velocity is a vector quantity.

Velocity is quickness of motion or action. A synonym is celerity; a simpler word is speed. In physics, velocity specifically refers to the measurement of the rate and direction of change in position of an object. It is a vector quantity that specifies both the speed of a body and its direction of motion.

Velocity is speed with a direction. Saying Ariel the Dog runs at 9 km/h (kilometers per hour) is a speed. But saying he runs 9 km/h Westwards is a velocity.

Answer to Essential Question 2.3: Some examples of constant velocity (or at least almost- constant velocity) motion include (among many others): • A car traveling at constant speed without changing direction. A hockey puck sliding across ice. A space probe that is drifting through interstellar space.

Uniform Velocity: A particle is said to move with uniform velocity if it moves along a fixed direction and covers equal displacements in equal intervals of time, however small these intervals of time may be. E.g., an object, as like a car moving with a speed of 10 km h-1 towards the north has uniform velocity.

1) Revolution of Earth around the sun. 2) Revolution of moon around the earth. 3) Velocity of a satellite around the earth. 4) Velocity of a car while driving.

Velocity is defined as a vector measurement of the rate and direction of motion. Put simply, velocity is the speed at which something moves in one direction. The speed of a car traveling north on a major freeway and the speed a rocket launching into space can both be measured using velocity.

A train moving on a straight road along a particular direction with constant velocity. b. A train starting from a station picking up velocity, then moving with a constant velocity and finally coming to rest at the next station.

Mr. An object can change velocity in a number of ways: it can slow down, it can speed up, or it can change direction. A change in speed, or a change in direction, or a change in both speed and direction means that the object has a change in velocity.

gravitational force

v= V*e_v. So the change of velocity can happen if at least one of them , namely the V magnitude or the direction of e_v changes. The change of velocity is characterized by the a acceleration , the time derivative of the velocity as follows. a = dv/dt.

There are three ways an object can accelerate: a change in velocity, a change in direction, or a change in both velocity and direction.

Because acceleration has both a magnitude and a direction, it is a vector quantity. Velocity is also a vector quantity. Acceleration is defined as the change in the velocity vector in a time interval, divided by the time interval. The key feature of any particle accelerator is the accelerating electric field.
