Question

Q.1. Find odd one out :-
a). Negative acceleration, retardation, positive acceleration, deceleration.​

Answer 1

Answer:

Explanation:

weight is the odd one.... because speed, velocity and acceleration is related to motion of a body..

Answer 2

The odd one out among the given options is Positive acceleration.

• Negative acceleration is otherwise known as Retardation or Deceleration.
• If the velocity of any object increases with time, then it is called Positive acceleration.
• When the velocity of an object decreases with respect to time, then it is termed as Negative acceleration or Retardation or Deceleration.
• Launching a rocket, accelerating a vehicle, a free falling object, pedalling a bicycle, rowing a boat, aeroplane take off etc., are some examples of Positive acceleration.
• When we apply brakes in a moving car or throw a ball upwards, then negative acceleration acts on it.
• In general, Positive acceleration occurs when objects speed up and Negative acceleration occurs when objects slow down.
