Question

example of negative acceleration plzz give me answer who will give nice answer I'll mark them brainlist ​

Answer 1

Answer:

negative accerleration is known as retardation

Answer 2

Answer:

Hello

Here's the answer to your question..

Some common examples are :

→A car is moving with high velocity (say v1 = 100km/hr toward North) suddenly it's driver notices a dog crossing the road, applies the brake and reduces the velocity of car to zero(v2 = 0) in 10 seconds (t2 - t1 = 10). So v2 -v1 is negative, implies negative acceleration.A ball thrown up in sky with high velocity(say v1 = 10m/s) reach certain height, then stats falling back and reaches the starting point again with same speed but in opposite direction, (so velocity v2 = -10m/s). Here also v2 - v1 is negative, so negative acceleration.

→Dropping something on the floor would be most people's commonest experience of the phenomenon. There is a huge negative acceleration as the object's velocity reduces abruptly from the positive value it had in falling through the air to zero. The kinetic energy is converted to stress within the object, (often causing breakage) and/or a dent in the floor. 

→When you flop down on your bed, you undergo negative acceleration.

When you place an object on a table, the object undergoes negative acceleration too.

→A ball thrown up in sky with high velocity(say v1 = 10m/s) reach certain height, then stats falling back and reaches the starting point again with same speed but in opposite direction, (so velocity v2 = -10m/s). Here also v2 - v1 is negative, so negative acceleration.

→When a moving object is losing speed constantly with time, the motions is in negative acceleration, or deceleration. Just as object gaining speed with time is acceleration, the object losing speed with time is decelerated.

Hope this helps....
