Question

(i) A Racing car has uniform acceleration of 6 ms ? what distance will it cover in 20
sec after start?
(ii) What is negative acceleration ?​

Answer 1

Answer:

According to our principle, when an object is slowing down, the acceleration is in the opposite direction as the velocity. Thus, this object has a negative acceleration. ... When an object is speeding up, the acceleration is in the same direction as the velocity. Thus, this object also has a negative acceleration.
