The question displayed in the image asks if a car driving north at 10 m/s, then turning around and driving south at 10 m/s, is accelerating. The three possible answers are:

- a) The car is not accelerating.
- b) The car is accelerating to the North.
- c) The car is accelerating to the South.

### Solution:
Acceleration is the rate of change of velocity. Velocity is a vector quantity, meaning it has both magnitude (speed) and direction. In this scenario:

1. The car was moving north at 10 m/s, then it reversed direction to go south at 10 m/s. Even though the speed remains constant (10 m/s), the direction changes.
2. A change in direction, even with the same speed, constitutes a change in velocity. Therefore, the car is accelerating.
3. Since the car ends up moving south, the direction of acceleration is toward the south.

Thus, the correct answer is:

**c) The car is accelerating to the South.**

### Five Related Questions:
1. What is the difference between speed and velocity?
2. How is acceleration calculated when both speed and direction change?
3. Can an object be accelerating if its speed is constant? If so, in what cases?
4. How does negative acceleration (deceleration) relate to the direction of motion?
5. What is the formula for calculating acceleration in one-dimensional motion?

### Tip:
Remember, acceleration can occur due to changes in speed, direction, or both. Even if an object maintains a constant speed, changing its direction results in acceleration!

A car driving North at a speed of 10 m/s along a street turns around and starts going 10 m/s South. Is this car accelerating? If so, in which direction?

Explore the concept of acceleration when a car changes direction from North to South while maintaining a constant speed. Learn why the change in velocity results in acceleration, even with constant speed. Ideal for high school students studying kinematics and vector quantities.
