some may feel speed and velocity are same terms but both are diffrent,let seehow?
Speed=distance travelled/time,that means it depents on how much distance you travelled,its a scalar quantity that means it dont depents on the direction
velocity:it depents on diaplacement,ie;velocity=displacement/time,displacement is the measure of smallest distance between mean position and last,its a vecter quatity,so its value can be negetive,+ve,and may zero
Speed is just a number; velocity includes information about the direction. In physical terms, speed is a scalar, whereas velocity is a vector.
Speed is just a number; velocity includes information about the direction. In physical terms, speed is a scalar, whereas velocity is a vector.
Velocity includes direction in addition to speed, whereas speed is the magnitude of velocity without direction. In other words, velocity is a vector quantity while speed is a scalar quantity. Velocity gives information about both the speed and the direction of motion, whereas speed only provides information about how fast an object is moving.
Speed is a scalar quantity that measures how fast an object is moving, while velocity is a vector quantity that includes both the speed of an object and its direction of motion. Speed is just the magnitude of velocity.
Speed in a specified direction is referred to as velocity. Velocity is a vector quantity that includes information about both the speed and direction of an object's motion.
Speed and velocity
Yes, phase velocity can exceed the speed of light in certain mediums. This is known as superluminal phase velocity. However, this does not violate the principle of causality or the speed of light in vacuum as it is the group velocity, rather than the phase velocity, that carries the information in a wave.
If the direction of motion is constant then the velocity is the same as the speed in that direction. If the direction is not constant, the information given is nowhere near sufficient to calculate the velocity.
Velocity is a vector quantity, which means it is made up of more than one numeric value. Velocity vectors must contain information on speed and direction.
To extract the speed from velocity, which is a vector quantity, you take the magnitude of the velocity vector. The magnitude is the speed component of the velocity vector, indicating only the numerical value without any direction information. This gives you the scalar quantity of the speed.
Speed is a scalar quantity that represents the rate at which an object moves, whereas velocity is a vector quantity that includes both the speed and the direction of motion. Both speed and velocity measure how fast an object is moving; however, velocity provides additional information about the direction of motion, while speed does not.
Velocity refers to the rate of change of an object's position in a specific direction, while speed is the rate at which an object covers distance. Velocity includes direction information, whereas speed does not. Velocity is a vector quantity, whereas speed is a scalar quantity.
