The correct answer is: speed and velocity, but no acceleration.
The correct answer is: speed, but neither velocity nor acceleration.
To understand why, let's clarify the meanings of these terms:
- Speed refers to how fast an object is moving in a specific direction, regardless of whether it's changing direction or not.
- Velocity refers to the speed of an object in a specific direction, taking into account its change in position with respect to time.
- Acceleration refers to the rate at which an object's velocity is changing over time.
In the given scenario, the car is traveling west at a constant rate, meaning its speed is constant. However, since the car is traveling in one direction without changing its velocity or accelerating, it does not experience any changes in its direction or changes in its position with respect to time. Therefore, it has neither velocity nor acceleration. Only its speed is present in this case.
The correct answer is:
A car that is traveling west at a constant rate has speed, but neither velocity nor acceleration.
