Speed-Time Graph: Straight Line Parallel to Time Axis
Graph Characteristics:
– Shape: The speed-time graph appears as a straight horizontal line parallel to the time axis.
– Representation: This line signifies a specific type of motion or velocity pattern.
Motion Characteristics:
– Constant Speed:
– The straight line on the graph indicates that the object maintains a consistent speed throughout the recorded time interval.
– The object moves at a steady pace without any changes in its velocity.
– Uniform Motion:
– There is no acceleration or deceleration present as the speed remains constant.
– The object experiences uniform motion with a steady and unchanging speed.
Interpretation:
– Consistent Velocity:
– The line’s parallel nature to the time axis implies that the object’s speed remains unchanged over the given time period.
– Absence of Acceleration or Deceleration:
– No change in the rate of speed signifies a lack of acceleration or deceleration during the recorded time.
Conclusion:
– A speed-time graph showing a straight line parallel to the time axis indicates an object moving at a constant speed. This signifies that the object maintains a steady velocity without any acceleration or deceleration throughout the recorded time interval.

1. Scenario:
– Straight Line Motion: The condition arises when an object moves along a straight path without changing direction during its motion.
2. Average Speed and Average Velocity:
– Average Speed: Average speed is a scalar quantity that measures the total distance travelled by an object over a given time interval.
– Average Velocity: Average velocity is a vector quantity that accounts for both the magnitude and direction of an object’s motion, measuring the displacement divided by time.
3. Equality Condition:
– When an object moves in a straight line without changing direction, its displacement (change in position) and the total distance travelled will be the same.
– As a result, in this scenario, the magnitude of the average velocity (which includes direction) will be equal to the average speed.
4. Explanation:
– Straight Line Motion: In this specific case, since the object moves along a straight path, there is no change in direction throughout its motion.
– Equal Displacement and Distance Travelled: As the object covers distance along the straight line, its displacement (which determines average velocity) will have the same magnitude as the distance travelled (which determines average speed).
5. Conclusion:
– Therefore, under the condition where an object moves along a straight line without changing direction, the magnitude of its average velocity will be equal to its average speed.
Importance:
– Understanding this condition is crucial as it illustrates a scenario where the distinction between average velocity and average speed is eliminated due to the object’s motion occurring solely in a straight line.

Uniform motion describes the movement of an object with a constant speed in a consistent direction without any change in velocity. Understanding the characteristics of the path of an object in uniform motion is essential in analyzing its motion patterns.
Path of an Object in Uniform Motion:
1. Constant Speed:
– In uniform motion, the object maintains a constant or consistent speed throughout its motion.
– The speed remains unchanged, indicating that the object covers equal distances in equal intervals of time.
2. Constant Direction:
– The object moves in a specific direction without any deviation or change in its path.
– The direction of motion remains constant, ensuring that the object continues to move in the same path without altering its course.
3. Straight Line Path:
– Due to the object’s constant speed and direction, the path followed by the object in uniform motion is a straight line.
– The motion of the object can be represented as a simple, direct, and linear path without any curves, bends, or deviations.
4. Implications of Straight Line Path:
– The straight-line path signifies that the object covers equal distances in equal time intervals, indicating consistent speed and direction.
– It simplifies the object’s trajectory into a predictable and straightforward course, making it easily understandable and analyzable.
Conclusion:
In summary, an object in uniform motion moves with a constant speed and in a constant direction, resulting in a path that is a straight line. This straight-line path is a characteristic feature of uniform motion, signifying the object’s consistent and unchanging motion without deviations or alterations in speed or direction.

(i) Uniform Acceleration:
Uniform acceleration refers to the motion of an object where its velocity changes at a constant rate over equal intervals of time. In simpler terms, it means that the object’s speed increases or decreases by the same amount in each equal interval of time. Mathematically, this translates to a consistent change in velocity per unit of time.
Characteristics of Uniform Acceleration:
1. Constant Change in Velocity: In uniform acceleration, the change in velocity remains constant per unit of time.
2. Equal Intervals of Time: The object experiences identical changes in velocity during equal intervals of time.
3. Linear Relationship Between Time and Velocity: The relationship between time and velocity is linear in uniform acceleration scenarios.
Example: An object moving in a straight line under the influence of gravity near the Earth’s surface demonstrates uniform acceleration as its velocity increases by approximately 9.8 m/s every second.
(ii) Non-Uniform Acceleration:
Non-uniform acceleration describes the motion of an object where its velocity changes irregularly, either increasing or decreasing, at a non-constant rate. In this case, the object’s speed changes by different amounts during equal intervals of time.
Characteristics of Non-Uniform Acceleration:
1. Varying Rate of Change in Velocity: In non-uniform acceleration, the change in velocity per unit of time is not consistent.
2. Unequal Intervals of Time: The object experiences different changes in velocity during equal intervals of time.
3. Non-Linear Relationship Between Time and Velocity: The relationship between time and velocity is not linear; it may follow a curve or exhibit varying rates of change.
Example: A car’s motion during its journey where it accelerates, then decelerates, and later accelerates again showcases non-uniform acceleration due to its varying rates of change in velocity over time.
In summary, uniform acceleration demonstrates a consistent and constant change in velocity over time, while non-uniform acceleration showcases irregular changes in velocity, either increasing or decreasing, over equal time intervals.
