velocity, but neither acceleration nor speed
The correct answer is velocity, but neither acceleration nor speed. When a car is traveling west at a constant rate, it has a constant velocity in the westward direction. Velocity refers to both the speed and the direction of motion. Since the car is traveling at a constant rate, it means its speed is not changing and there is no acceleration. Therefore, velocity is present, but neither acceleration nor speed.
A car that is traveling west at a constant rate has velocity, but neither acceleration nor speed.
To understand why, let's review the definitions of velocity, speed, and acceleration:
- Velocity: Velocity is a vector quantity that includes both the speed and direction of an object's motion. In this case, since the car is traveling west, its velocity would be in the westward direction. Velocity is expressed in units of distance/time (e.g., meters per second or miles per hour).
- Speed: Speed is a scalar quantity that only considers the magnitude of an object's motion, disregarding its direction. It is the distance traveled by an object per unit time. For example, if the car is traveling at a constant rate of 60 miles per hour, its speed would be 60 mph, irrespective of the direction.
- Acceleration: Acceleration refers to the rate at which an object's velocity changes. It is the change in velocity per unit time. If the car were to speed up or slow down, it would have an acceleration. However, in this scenario, it is mentioned that the car is traveling at a constant rate, so there is no change in velocity, and therefore no acceleration.
Hence, the correct answer is that the car has velocity but neither acceleration nor speed.
