Velocity is a measure of the speed and direction of an object's movement. It is calculated by dividing the change in an object's position by the change in time.
Velocity and speed are often used interchangeably, but they are different concepts. While speed only measures how fast an object is moving, velocity also takes into account the direction of movement.
The units of velocity are distance traveled (such as meters or feet) divided by time (such as seconds or minutes). The most common unit of velocity is meters per second (m/s).
Velocity can be represented on a graph by plotting the change in an object's position (y-axis) over time (x-axis). The slope of the line on the graph represents the object's velocity, with steeper slopes indicating higher velocity.
Acceleration is the rate of change of an object's velocity. If an object experiences a constant acceleration, its velocity will change at a constant rate. This means that the object's velocity will increase or decrease by the same amount every unit of time.
