Physics: Uniform and Non-uniform Motion

Uniform And Non-uniform Motion

• Uniform motion: An object moves with a constant velocity, covering equal distances in equal time intervals.
• Non-uniform motion: An object moves with a changing velocity, covering unequal distances in equal time intervals.

Displacement And Distance

• Displacement: The shortest distance between the initial and final positions of an object.
• Distance: The total length of the path traveled by an object.
• Key difference: Displacement is a vector quantity, while distance is a scalar quantity.

Velocity And Acceleration

• Velocity: The rate of change of an object's position with respect to time.
• Acceleration: The rate of change of an object's velocity.
• Units: Velocity (m/s), Acceleration (m/s²)
• Key equation: a = Δv / Δt, where a is acceleration, Δv is change in velocity, and Δt is time interval.

Motion Graphs

• Types of graphs:
  • Distance-time graph: A straight line indicates uniform motion, while a curved line indicates non-uniform motion.
  • Velocity-time graph: A straight line indicates uniform acceleration, while a curved line indicates non-uniform acceleration.
  • Acceleration-time graph: A straight line indicates uniform acceleration, while a curved line indicates non-uniform acceleration.
• Interpretation: The slope of a graph represents the rate of change of the corresponding quantity.

Relative Motion

• Relative motion: The motion of an object relative to a reference frame or another object.
• Key concept: Motion is relative, and the same motion can be described differently from different reference frames.
• Types of relative motion:
  • Translational motion: Object moves in a straight line relative to a reference frame.
  • Rotational motion: Object rotates around a fixed axis relative to a reference frame.
  • Circular motion: Object moves in a circular path relative to a reference frame.

Motion Basics

• Motion types: Uniform motion (constant velocity, equal distances in equal time) and non-uniform motion (changing velocity, unequal distances in equal time)

Displacement and Distance

• Displacement definition: Shortest distance between initial and final positions
• Distance definition: Total length of the path traveled by an object
• Key difference: Displacement is a vector quantity, while distance is a scalar quantity

Velocity and Acceleration

• Velocity definition: Rate of change of an object's position with respect to time
• Acceleration definition: Rate of change of an object's velocity
• Units: Velocity (m/s), Acceleration (m/s²)
• Key equation: a = Δv / Δt, where a is acceleration, Δv is change in velocity, and Δt is time interval

Motion Graphs

• Graph types: Distance-time, velocity-time, and acceleration-time graphs
• Graph interpretation: Slope of a graph represents the rate of change of the corresponding quantity
• Uniform motion indication: Straight line on distance-time graph
• Non-uniform motion indication: Curved line on distance-time graph
• Uniform acceleration indication: Straight line on velocity-time graph
• Non-uniform acceleration indication: Curved line on velocity-time graph

Relative Motion

• Relative motion definition: Motion of an object relative to a reference frame or another object
• Key concept: Motion is relative, and the same motion can be described differently from different reference frames
• Types of relative motion: Translational, rotational, and circular motion
• Translational motion: Object moves in a straight line relative to a reference frame
• Rotational motion: Object rotates around a fixed axis relative to a reference frame
• Circular motion: Object moves in a circular path relative to a reference frame
