* The acceleration must be in the opposite direction to the initial velocity. If the acceleration is in the same direction as the velocity, the object will simply speed up.
* The acceleration must be applied for a long enough time. The longer the acceleration acts, the greater the change in velocity.
Here's how it works:
Imagine a car moving to the right (positive direction) at a constant speed. If we apply a constant acceleration to the left (negative direction), the car will slow down. Eventually, the car will come to a stop. If we continue applying the acceleration, the car will start moving to the left, meaning its velocity has reversed.
Key Points:
* Constant acceleration does not mean constant velocity. Constant acceleration implies a steady change in velocity.
* The direction of acceleration determines the direction of the velocity change.
* The magnitude of acceleration and the duration of its application determine the magnitude of the velocity change.
