## What is the slope of a speed vs time graph?

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 the line slopes upward from left to right, this means the object is speeding up.

## What is the slope of the graph equals to?

The slope equals the rise divided by the run: . You can determine the slope of a line from its graph by looking at the rise and run. One characteristic of a line is that its slope is constant all the way along it.

## What does the slope of a position vs time graph represent?

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 does velocity and speed have in common?

Velocity is a vector quantity and has both magnitude and direction. In fact, for a straight line motion, the speed and velocity of an object are the same (since distance and displacement will be the same). Speed and velocity are measured in the same units: meters per second or m/s.

## What is difference between speed and velocity Class 9?

Answer. Speed is defined as the distance travelled by a body in a given interval of time. Velocity is defined as the displacement of a body in a given interval of time. It is a scalar quantity.

## How can we use speed and velocity in our daily lives?

• Examples:
• 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.
• 5) Velocity of a ball when hitted with a bat.
• 6). Velocity of water coming from a tap.
• 7). Velocity of the train .

## What is velocity in real life?

By definition, velocity refers to how fast a car moves towards a particular direction. So, if two cars move with the same speed towards different direction, they are moving with different velocities. To change the speed of a car, you push the accelerator of the car.

## Where do we use velocity in real life?

A car’s speedometer, for example, shows the magnitude—but not the direction—of the instantaneous velocity of the car. Police give tickets based on instantaneous velocity, but when calculating how long it will take to get from one place to another on a road trip, you need to use average velocity.
