Which choice represents velocity?(1 point)
c) 10 m/s
Velocity is a vector quantity that represents the rate at which an object changes its position. It has both magnitude and direction. Therefore, the choice that represents velocity is a vector quantity.
To determine which choice represents velocity, we first need to understand what velocity is. Velocity is a vector quantity that describes the rate at which an object changes its position in a particular direction. It is the combination of speed (the magnitude of the velocity) and direction.
Now, let's look at the given choices and evaluate which one represents velocity:
1. Distance covered by an object
2. Speed of an object
3. Time taken by an object to travel a certain distance
4. Displacement of an object
Option 2, "Speed of an object," does not fully represent velocity because it only describes the magnitude or numerical value of the rate of movement. It does not indicate the direction.
Option 4, "Displacement of an object," represents velocity since it specifies both the magnitude and the direction of the change in position. Displacement is the shortest distance between the initial and final positions of an object, taking into account the direction.
Therefore, the correct choice that represents velocity is option 4, "Displacement of an object."
