Speed unlike acceleration or velocity does not specify _____?
A. Mass
B. Time
C. Direction
D. Distance
A. Mass
That’s wrong
I apologize for the mistake. The correct answer is D. Distance. Speed is a scalar quantity that only describes how fast an object is moving, while distance is a measure of the total path length traveled.
The correct answer is A. Mass.
To understand why speed does not specify mass, let's first break down what speed is. Speed is a scalar quantity that measures the rate at which an object covers distance. It is a measure of how fast an object is moving, without any regard to the direction in which it is moving.
Now, let's look at the other options:
B. Time: Speed is directly related to time. It tells us how much distance an object covers in a given amount of time.
C. Direction: Speed, unlike velocity, does not take into account the direction in which an object is moving. For example, if an object moves from point A to point B, regardless of whether it traveled in a straight line or took a curved path, its speed would remain the same.
D. Distance: Speed is directly related to the distance an object travels. It tells us how much distance an object covers in a given amount of time.
A. Mass: Mass is a measure of the amount of matter in an object. It is unrelated to an object's speed. Two objects with the same speed can have different masses. For example, a small car and a large truck can both be traveling at the same speed, but the truck will have a greater mass compared to the car.
