Which statement is true about speed and velocity?(1 point) Responses Both speed and velocity are vector quantities. Both speed and velocity are vector quantities. Speed is a scalar quantity, and velocity is a vector quantity. Speed is a scalar quantity, and velocity is a vector quantity. Speed is a vector quantity, and velocity is a scalar quantity. Speed is a vector quantity, and velocity is a scalar quantity. Both speed and velocity are scalar quantities.
Speed is a scalar quantity, and velocity is a vector quantity.
is this right
Yes, that is correct. Speed is a scalar quantity because it only has magnitude (a numerical value) and no direction, while velocity is a vector quantity because it has both magnitude and direction.
The correct statement is: Speed is a scalar quantity, and velocity is a vector quantity.
To understand why this statement is true, we need to understand the definitions of speed and velocity.
Speed refers to the rate at which an object covers a distance. It is a scalar quantity because it only has magnitude (size) and no direction. For example, if a car is traveling at a speed of 60 km/h, it tells us how fast the car is moving but not the direction in which it is moving.
On the other hand, velocity refers to the rate at which an object changes its position. It is a vector quantity because it has both magnitude and direction. Velocity includes information about the object's speed as well as the direction in which it is moving. For example, if a car is traveling at a velocity of 60 km/h, north, it tells us the speed (60 km/h) and the direction (north) in which the car is moving.
Therefore, speed is a scalar quantity because it has only magnitude, while velocity is a vector quantity because it has both magnitude and direction.
