the question is incomplete, but my guesses are that

Power --- Watts

If you give the complete question, I can answer the last one!

Answer 2

The answer of the given match are mentioned in explanation part.

Explanation:

1. Joule - Work
2. Negative acceleration - deceleration​

• Joule is the SI unit for measure the capacity to do work.
• One joule equals the work done by a force of one newton acting over a distance of one meter.
• So, work (joules) = force (newtons) x distance (meters).
• Negative accelerations also known as deceleration.
• It means that over time, instead of speeding up, you are slowing down, your velocity is continously decreasing.
• When a ball is dropped, it is accelerating in the downward direction, it is a negative acceleration.
