Answer :
Answer:
Here are the terms matched with their correct definitions:
Velocity: A. Vector quantity including displacement per time with direction
Acceleration: C. Change of velocity with time
Speed: E. Scalar quantity including displacement per time.
Centripetal Acceleration: B. Acceleration of an object moving in a circular path
Circular Motion: D. Velocity would have a continuously changing direction
Explanation:
Explanations for each term:
- Velocity: A measure of how fast something is moving in a specific direction. It is a vector quantity, meaning it includes both speed and direction.
- Acceleration: The rate at which an object's velocity changes over time. It can involve an increase or decrease in speed and/or a change in direction.
- Speed: The rate at which an object covers distance. It is a scalar quantity, meaning it only has magnitude and no direction.
- Centripetal Acceleration: The acceleration directed towards the center of a circular path that keeps an object moving in that path. It is necessary for maintaining circular motion.
- Circular Motion: Movement of an object along the circumference of a circle or rotation along a circular path, where the direction of velocity constantly changes.
Velocity - A. Vector quantity including displacement per time with direction. Acceleration - C. Change of velocity with time. Speed - E. Scalar quantity including displacement per time. Centripetal Acceleration - B. Acceleration of an object moving in a circular path. Circular Motion - D. Velocity would have a continuously changing direction.
Here are the closest matching pairs with their corresponding definitions:
- Velocity - Vector quantity including displacement per time with direction.
- Acceleration - Change of velocity with time.
- Speed - Scalar quantity including displacement per time.
- Centripetal Acceleration - Acceleration of an object moving in a circular path.
- Circular Motion - Velocity would have a continuously changing direction.
To summarize, velocity is a vector that needs direction, acceleration is any change in velocity divided by time, speed is a scalar with no reference to direction, centripetal acceleration describes an object moving in a circular path, and circular motion implies a changing direction of velocity.
