The Law of Inertia states that an object in motion remains in motion and an object at rest remains at rest unless and unbalanced, outside force acts upon that object.

Because the passengers are "attached" to the bus, they have the same inertia as the bus. But because the passengers are technically seperated, they have their own inertia. So when the bus is slowing down to a stop, the passengers inertia are to keep moving forward. As the bus moves back, the passengers want to keep moving forward. Which is why they lurch forward as the bus decelerates.

What would have happened if the earth rotated from east to west?

If it had always rotated the other way things would probably be similar although the continents might not have identical shapes to what they are now *************************************** When a vehicle suddenly stops, the passengers are thrown forward - it is called momentum. If the earth suddenly reversed its spinning, the momentum of the worlds oceans would surge forward and completely wash over the land.


Stick-slip motion between lithospheric plates is what causes an?

earthquake. This motion occurs when two plates along a fault line become stuck due to friction, building up stress until they suddenly slip past each other, releasing energy in the form of seismic waves.


Which side is the wet side of a hurricane?

The right side of a hurricane is typically the wet side, as it is where the fastest winds are located and where the storm's forward motion adds to the rainfall intensity.


What is the motion of plates at a transform boundary?

At a transform boundary, plates slide past each other horizontally in opposite directions. This movement is called lateral sliding. It can create earthquakes as the plates become stuck and then suddenly release along the boundary.


How do gliders transformed potential energy into Kinetic energy?

Gilders transformed Potential energy into Kinetic energy by if a Motor doesn't work the gliders would have the machine you are in just slip from potential energy (the motor) into Kinetic energy (is the energy of motion).

When a moving bus suddenly stop the passenger jerking forward on which law defined here?

The passenger jerking forward when a bus suddenly stops can be explained by Newton's First Law of Motion, also known as the law of inertia. This law states that an object in motion tends to stay in motion unless acted upon by an external force, such as the sudden stop of the bus which causes the passenger to continue moving forward.


How does an airbag minimize injury injury in a collision?

AIR BAGS soften passenger's falls and prevent passenger's neck from breaking.They help absorb the kinetic energy of the upper body's forward motion when the vehicles forward progress is suddenly halted by impact.


When a bus suddenly stop why passenger move forward?

When a bus suddenly stops, the inertia of the passengers causes them to continue moving forward until another force (like friction or a seatbelt) slows them down. This phenomenon is known as inertia, where an object in motion tends to stay in motion unless acted upon by an external force.


When a train suddenly moves forward the passenger standing in the compartment tends to fall backward?

Yes--because of Newton's first law, the passenger wishes to stay in its constant state of motion, which is standing still in this case. Hence, when the train starts to move forward, the passenger will want to stay at the point he/she was and will fall backwards.


What happens to the forward motion of a passenger in a head-on auto accident?

When the vehicle coems to a sudden stop the passenger's forward motion continues until something stops it - either the seat-belt (the fabric of which stretches slightly to absorb the force, and from which the passenger is thrown back against their seat by a 'recoil'), or the windscreen. If it is the windscreen which stops the passenger's forward motion, the impact usually breaks the windscreen (and some of the passenger's bones) and the passenger may continue their forward motion by going through the glass. Otherwise the impact reaction on the passenger may well be enough to snap their neck and kill them.


Why are passengers thrown forward when a moving vehicle suddenly stop?

Passengers are thrown forward when a moving vehicle suddenly stops due to inertia. Inertia is the tendency of an object in motion to stay in motion, so when the vehicle stops suddenly, the passengers continue moving forward until they are stopped by the seat belt or another object.


A passenger standing in a fully loaded bus which is at rest tends to move backward when the driver suddenly starts the bus?

The passenger tends to move backward when the bus starts because of inertia. The passenger's body wants to stay at rest due to Newton's First Law of Motion, so when the bus accelerates forward, the passenger appears to move backward relative to the bus.


When a car stops suddenly the passengers tend to move forward relative to their seats Why?

When car was moving, passengers were also moving. When car suddenly stops, the moving passengers try to maintain their state of forward motion because of their inertia. so they move forward relative to their seats...


Why a passenger standing in a fully loaded bus which is at rest tends to move backward when the driver suddenly starts the bus?

This is what we call "Inertia of Rest" The upper portion remains at rest though the feet attached to the bus starts moving. So relatively the head has to go back as it lags. So he falls backward. By holding the rod above the head with a grip the passenger pulls his head forward so as to avoid falling back. As the bus moves with uniform motion then whole body will be in motion. Same way as the driver applies brake and brings the bus to rest, the passenger falls forward. This is due to "intertia of motion"
