⚖ Conservation of Momentum

m_astro × v_astro = m_box × v_box — the astronaut's mass (78 kg) is far greater than the box, so they drift backward far slower than the box flies forward.

Newton's First Law

An object at rest stays at rest, and an object in motion stays in motion at constant velocity, unless acted upon by an external force. This resistance to change is called inertia.

🔮 Predict the Outcome

What happens to the box when the truck brakes suddenly?

Box moves backward, away from the cab Box stays perfectly still Box keeps moving forward, toward the cab

🚗

Seatbelt

Stops your body's forward inertia during sudden braking.

🚌

Bus Brakes

Standing passengers lurch forward when the bus stops fast.

📖

Book on Table

Stays still until you push it — inertia at rest.

🪙

Coin & Card

Flick the card away and the coin drops straight down.

⚽

Football

Stays at rest on the ground until kicked with force.

Shopping Cart

Heavier, fully-loaded carts resist changes in speed more.
