Which of the following is a scalar quantity?(1 point) Responses acceleration acceleration speed speed displacement displacement velocity velocity
speed
The scalar quantity among the options listed is speed.
To determine which of the given options is a scalar quantity, we need to understand the nature of scalar and vector quantities.
Scalar quantities are mathematical quantities that have only magnitude (size or value) and no direction. On the other hand, vector quantities have both magnitude and direction.
Given the options, acceleration, displacement, and velocity are vector quantities because they have both magnitude and direction associated with them.
Speed, on the other hand, is a scalar quantity because it only represents the magnitude or the numerical value of how fast an object is moving. It does not include any information about the direction of motion.
Therefore, the correct answer is speed.
