उत्तर
-
Type of Motion:Uniform Acceleration
-
The graph shows a straight line with a positive slope, indicating that velocity increases at a constant rate over time.
-
This means the object is accelerating uniformly.
Example:
A car increasing its speed steadily on a straight road (e.g., from 0 km/h to 60 km/h in 10 seconds at a constant rate). -
-
Type of Motion: Non-Uniform Retardation (Deceleration)
-
The graph shows a curved line with a decreasing slope, indicating that velocity is decreasing over time, but not at a constant rate.
-
This means the object is slowing down, and the rate of slowing down is changing.
Example:
A bicycle coming to a stop when brakes are applied gently and gradually. -
