Question

When is the acceleration taken as negative​

Answer 1

Hey mate!!!!!

The acceleration is taken as negative if it is working in the direction opposite to the velocity.

For ex, if we throw a ball up, then the acceleration of gravity will pull it down which means in opposite direction so it is negative.

Second example If we apply brakes,the acceleration works in opposite and hence the vehicle stops so it is also negative.

Hope it helps dear friend ☺️✌️✌️✌️
