Rainbow mindmap - Motion

🌈 Rainbow Mind Map: Motion

• 🔴 Motion: Motion is the change in position of an object with respect to time.
• 🟠 Rest & Motion are Relative: A passenger sitting inside a moving bus is at rest w.r.t. bus but in motion w.r.t. the ground.
• 🟡 Types of Motion: - Translatory (rectilinear & curvilinear)
  - Circular (fan blade)
  - Oscillatory (swing)
  - Periodic (simple pendulum)
  - Non-periodic (car on road)
  - Random (motion of insects)
• 🟢 Uniform Motion: Object covers equal distances in equal intervals of time, e.g., a car moving on a straight highway at constant speed.
• 🔵 Non-uniform Motion: Object covers unequal distances in equal intervals of time, e.g., a car in city traffic.
• 🟣 Speed: Speed = Distance ÷ Time; it tells how fast an object moves. Average Speed = Total Distance ÷ Total Time.
• 🟪 Weight & Mass: Mass is constant everywhere. Weight = Mass × g (changes with gravity).

Think & Answer:
1. A car covers 60 km in 1 hour and 30 km in the next hour. Is its motion uniform or non-uniform?
2. If your mass is 45 kg, what will be your weight on Earth (g = 9.8 m/s²)?
