Linear speed (or velocity) is the measure of the displacement of an object over time in a straight line. It is the rate of change of the distance travelled by the object per unit time. Linear velocity is a vector quantity, meaning it has both magnitude (speed) and direction. It is commonly measured in meters per second (m/s) or kilometers per hour (km/h).

Linear speed can be calculated by dividing the distance travelled by the time taken to travel that distance:

Linear speed = distance travelled / time taken

Alternatively, if the displacement of the object is known, the linear speed can be calculated as the derivative of the displacement with respect to time:

Linear velocity = d(displacement) / dt

Linear speed plays a crucial role in many areas of physics, including mechanics, kinematics, and dynamics. It is used to describe the motion of objects, the energy they possess, and the forces acting upon them.

The formula for determining the linear speed/velocity is defined as:
\(v\) \(=\) \(\dfrac{d}{t}\)
\(v\): the velocity/speed
\(d\): the distance
\(t\): the time
The SI unit of linear speed/velocity is: \(meter/second \text{ }(m/s)\)
