Speed-time graphs. The speed-time graph below illustrates how the speed of an object changes with time. A horizontal line on a speed-time graph represents a steady speed....
The area under a velocity-time graph is equal to the distance travelled by an object. To find the area under the graph, break it down into small shapes and add the areas of the shapes.
Speed-time graphs show speed on the vertical axis and time on the horizontal axis. The gradient of a speed-time graph represents acceleration because \(gradient =...
The knot (/ n ɒ t /) is a unit of speed equal to one nautical mile per hour, exactly 1.852 km/h (approximately 1.151 mph or 0.514 m/s). [1] [2] The ISO standard symbol for the knot is kn. [3]

- The speed of a body in a specific direction is the measure of Velocity. Rate of change in displacement with respect to time is known as velocity. V...
- Speed is measured as the ratio of distance to the time in which the distance was covered. Speed is a scalar quantity as it has only direction and n...
- There are four types of speed and they are: Uniform speed Variable speed Average speed Instantaneous speed
- When an object is moving with variable speed, then the speed of that object at any instant of time is known as instantaneous speed.
- Average velocity is a vector quantity. Average velocity is defined as the change in position or displacement (∆x) divided by the time intervals (∆t...

What is a Speed Time Graph? Speed time graphs, as the name implies, indicate the relationship between speed and time. In a typical speed time graph, the x-axis represents time while the y-axis represents speed.
