Motion in one dimension refers to the movement of an object along a straight line. It can be described by various physical quantities such as displacement, velocity, and acceleration. Here is a document summarizing the key concepts and equations related to motion in one dimension:

Motion in One Dimension

1. Displacement (Δx):
- The change in position of an object.
- It is a vector quantity, indicating both magnitude and direction.

2. Average Velocity (v):
- The displacement divided by the time taken.
- v = Δx / Δt
- Unit: m/s (meters per second)

3. Instantaneous Velocity (v):
- The velocity at a specific instant in time.
- It is the derivative of the displacement with respect to time.
- v = dx / dt

4. Average Speed (s):
- The total distance traveled divided by the time taken.
- s = total distance / Δt
- Unit: m/s (meters per second)

5. Acceleration (a):
- The rate of change of velocity.
- a = Δv / Δt
- It is a vector quantity, indicating both magnitude and direction.
- Unit: m/s² (meters per second squared)

6. Equations of Motion:
- These equations relate displacement, velocity, acceleration, and time for an object in motion.

a. v = u + at
- Final velocity (v) = Initial velocity (u) + (acceleration × time)

b. Δx = ut + (1/2)at²
- Displacement (Δx) = Initial velocity (u) × time + (1/2) × (acceleration × time²)

c. v² = u² + 2aΔx
- Final velocity squared (v²) = Initial velocity squared (u²) + 2 × (acceleration × displacement)

d. Δx = (v + u) / 2 × t
- Displacement (Δx) = (Initial velocity + Final velocity) / 2 × time

7. Graphs of Motion:
- The relationship between displacement, velocity, and acceleration can be represented graphically.

a. Displacement-Time Graph:
- The slope of the graph represents velocity.
- The area under the graph represents displacement.

b. Velocity-Time Graph:
- The slope of the graph represents acceleration.
- The area under the graph represents displacement.

c. Acceleration-Time Graph:
- The area under the graph represents change in velocity.

Remember to apply the appropriate sign conventions (+/-) for direction while solving numerical problems. Practice using these equations and graphs to analyze and solve problems related to motion in one dimension.
