🧠 Why Do You Get
Pulled Back When a Vehicle Starts Moving?
Have you ever been
seated in a stationary car or bus, and the moment it starts moving, you feel a
sudden pull backward? This common experience can seem
mysterious—but it's actually pure science!
⚙️ The Science Behind It –
Newton's First Law
This happens because
of Newton’s First Law of Motion, also known as the Law of
Inertia. The law states:
"An object at rest will remain at rest, and an object in motion will remain in motion, unless acted upon by an external force."
When you're sitting in
a vehicle that is at rest, your body is also at rest. The moment
the vehicle starts moving forward, the vehicle moves before your body
does. Your body resists this change in motion due to
inertia, so it feels like you’re being pulled backward.
🚍 Real-Life Example
Imagine sitting in a
bus that’s parked at the stop. The driver suddenly accelerates:
·
The bus moves
forward.
·
Your body tries to
remain in the same place (at rest).
·
This causes your
back to press against the seat, and you feel a backward jerk.
🧒 Example for Kids
Think about standing on
a skateboard. If someone suddenly pushes the skateboard forward, your feet move
with it—but the rest of your body wants to stay in place. You might even fall
backward!

🧪 Simple Experiment
You Can Try
Take a card and place a
coin on top of it. Now, quickly pull the card:
·
The card moves.
·
The coin stays
in place (and falls straight down).
That’s inertia at work
again!
📚 In Short:
·
Your body wants
to stay at rest.
·
The
vehicle moves forward.
·
You feel
a pull backward due to inertia.
📘 Fun Fact:
This same law explains
why you lurch forward when a speeding car suddenly stops. Your
body tries to keep moving even when the vehicle has stopped!

✅ Conclusion
So, next time you're in
a moving vehicle and feel that backward pull, just smile—you’re
experiencing Newton’s First Law of Motion in real life! 🚗💨
