Question

plz give me answer ​

Answer 1

Answer:

ACCELERATION:- In physics or physical science, acceleration (symbol: a) is defined as the rate of change (or derivative with respect to time) of velocity. It is thus a vector quantity with dimension length/time². In SI units, acceleration is measured in meters/second² using an accelerometer.

When is acceleration of a body negative ?

Ans:- 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.

The two examples of situations in which acceleration of the body is negative are:-

1) When a moving body slows down due to any reason, the speed decreases and the acceleration is negative.

2) A cyclist is cycling and stops after 60 seconds.
