1. What is Motion?
Motion is a change in position of an object with respect to time.
2. Types of Motion:
Translational Motion – movement in a straight line (e.g., a car driving on
a road).
Rotational Motion – movement around a fixed point (e.g., a spinning
wheel).
Oscillatory Motion – repeated back and forth movement (e.g., a
swinging pendulum).
3. Distance vs. Displacement:
Distance: Total path covered (scalar quantity).
Displacement: Shortest path from start to end (vector quantity, has
direction).
4. Speed vs. Velocity:
Speed = Distance / Time (scalar)
Velocity = Displacement / Time (vector)
5. Acceleration:
Change in velocity over time.
Formula: a = (v - u) / t
where v = final velocity, u = initial velocity, t = time
6. Uniform vs. Non-uniform Motion:
Uniform Motion: Constant speed.
Non-uniform Motion: Changing speed.
Flashcards: Motion
Q: What is the formula for speed?
A: Speed = Distance ÷ Time
Q: What kind of quantity is displacement?
A: Vector (has direction)
Q: What does acceleration mean?
A: Rate of change of velocity
Q: Which type of motion does a swing show?
A: Oscillatory motion
Q: What is the difference between speed and velocity?
A: Velocity includes direction; speed does not.
