Which characteristic is constant for the car as it travels around the roundabout?
Speed
Velocity
Position
Direction
Direction
On a position-time graph, which of the following does the value of the slope indicate about the object? (1 point)
Total distance
Change in direction
Velocity
Change in position
The value of the slope indicates the velocity of the object.
The characteristic that is constant for the car as it travels around the roundabout is the direction.
The characteristic that remains constant for the car as it travels around the roundabout is the direction.
To understand this, let's break down the other options:
1. Speed: Speed refers to how fast an object is moving. While the car's speed may change as it negotiates the roundabout, accelerating or decelerating, it does not remain constant throughout the journey. Therefore, speed is not the correct answer.
2. Velocity: Velocity is the speed of an object in a specific direction. It incorporates both speed and direction. As the car negotiates the roundabout, its velocity will change because the direction of motion is constantly changing. Hence, velocity is not the correct answer either.
3. Position: Position refers to the location of an object. As the car travels around the roundabout, its position changes continuously. Therefore, position is not a constant characteristic.
4. Direction: The only characteristic that remains constant for the car as it travels around the roundabout is its direction. The car will always be facing in the same direction relative to the center of the roundabout. So, direction is the correct answer.
