difference between speed and velocity
Answers
Answer:
Explanation:he speed indicates the relationship between the distance traveled by an object and the time that this used to cover it. As such, it can be measured in meters, kilometers, miles, or knots (in the water environment), per hour, or per second.
Since speed is expressed according to distance and time, it is characterized by being a scalar quantity, which means that only numerical units are used to describe speed.
he rate expresses the ratio between the distance traveled by an object and the time it takes you to cross it towards a direction specific.
Basically, speed refers to the positional change of an object, from an initial reference point to the place to which this object has moved (the endpoint of movement), and to the time it has taken to do so.
Being a magnitude that also determines the direction in which the displacement occurs, the velocity is considered a vector magnitude.
Speed is measured in meters per second (m / s, according to the International System of Units), by direction.
In this sense, for an object to have a constant speed, it must move in a constant direction for a certain amount of time. Any change in direction will simply variations in speed.
Speed characteristics
Answer:
Speed, being a scalar quantity, is the rate at which an object covers distance. The average speed is the distance (a scalar quantity) per time ratio. Speed is ignorant of direction.
he other hand, velocity is a vector quantity; it is direction-aware. Velocity is the rate at which the position changes. The average velocity is the displacement or position change (a vector quantity) per time ratio.
