Question

What name is given to the speed in a specified direction?

Answer 1

Hint:The magnitude of the rate of change of an item's position with time or the magnitude of change of its position per unit of time is the speed (often referred to as v) of an object in daily use and in kinematics; it is therefore a scalar number. The average speed of an object in a given time interval is the item's distance travelled divided by the period's duration; the instantaneous speed is the average speed's limit as the interval's duration approaches zero.

Complete step by step answer:
Velocity refers to an object's speed in a certain direction. Velocity is also the pace at which an object's location changes in relation to a frame of reference and time. In its most basic form, velocity may be defined as the rate at which anything moves in a given direction. The rate of change of an object's location with regard to a frame of reference is its velocity, which is a function of time.

A definition of an object's speed and direction of motion is referred to as velocity. In kinematics, the branch of classical mechanics that explains the motion of bodies, velocity is a basic notion. Velocity is a physical vector quantity that requires both magnitude and direction to define.

Speed is the scalar absolute value (magnitude) of velocity, and it is a coherent derived unit whose quantity is measured in metres per second (m/s) in the SI (metric system). "5 metres per second east" is a vector, but "5 metres per second" is a scalar. The item has a changing velocity and is said to be undergoing acceleration if there is a change in speed, direction, or both.

Note:An object must have a constant speed in a constant direction to have a constant velocity. The object's motion is restricted to a straight route when it has a constant direction. As a result, motion along a straight line at a constant speed is referred to as constant velocity. An automobile travelling at a constant 20 km/h in a circular course, for example, has a constant speed but not a constant velocity since its direction varies. As a result, the automobile is regarded as accelerating.
