Retardation of the particle
Explanation:
As the velocity of an object increases, its acceleration also increases. Which means that it will have a positive sign.
Opposite happens when an object slows down. Same formula of acceleration is used but the answer will have a negative sign with it which will show the decrease in the velocity.
Such that an object moving with the speed of 3 m/s starts to slow down. Its acceleration will become negative.
A quantity having value of -4 m/s² may be the may be the Retardation of the particle
Explanation:
Quantity given here is
- 4 m/s²
unit is m/s²' hence L / T²
first check units
Speed of a particle has unit L/T
Hence not possible
Position of a particle will have unit L
Hence not possible
Velocity of the particle has unit L/T
Hence not possible
Retardation of the particle mean - ve acceleration
acceleration has unit L / T²
and - 4 is magnitude
hence - sign means - ve acceleration i.e. Retardation
A quantity having value of -4 m/s² may be the may be the Retardation of the particle
