Non-Uniform Motion Explained
Definition
An object is said to be in non-uniform motion if it covers unequal distances in equal intervals of time. This means the speed of the object is not constant, and the object is either accelerating or decelerating.
Key Characteristics
- The speed of the object keeps changing over time.
- The object may be accelerating (speed increasing) or decelerating (speed decreasing).
- The distance-time graph for non-uniform motion is a curved line.
- The velocity-time graph shows varying slope, indicating changing acceleration.
Examples of Non-Uniform Motion
- A car moving through traffic (stopping and accelerating frequently).
- A falling object under gravity (speed increases with time).
- A bicycle slowing down due to friction.
- A roller coaster moving up and down at different speeds.
