___________ in a particular direction is velocity.

Correct option is C

The correct answer is (c) Speed.

Velocity refers to the speed of an object in a particular direction. While speed is a scalar quantity that represents how fast an object is moving, velocity is a vector quantity that includes both the magnitude (speed) and the direction of motion. Therefore, velocity describes the rate at which an object changes its position in a specific direction.

Information Booster:

• Speed is the rate at which an object covers distance, but it does not include direction.
• Velocity includes both speed and direction, making it a vector quantity.
• Displacement is the shortest distance from the initial to the final position of an object, considering the direction.
• Acceleration refers to the rate at which velocity changes over time.
• Velocity can be positive, negative, or zero, depending on the direction of movement relative to a reference point.
• Velocity is crucial in describing motion, particularly when the direction of movement is important, such as in physics and engineering problems.
