Did the soccer ball accelerate?
Understand the Problem
The question is asking whether a soccer ball that hits a post and bounces back has accelerated. It provides options based on the change in velocity, speed, and other reasons to assess understanding of the concept of acceleration in physics.
Answer
Yes, because it changed velocity.
The final answer is Yes, because it changed velocity.
Answer for screen readers
The final answer is Yes, because it changed velocity.
More Information
Acceleration occurs when there is a change in velocity, which includes both speed and direction. Even if the speed remains constant, a change in direction, like bouncing back, indicates acceleration.
Tips
A common mistake is to focus only on speed when considering acceleration, forgetting that a change in direction also counts.
