Why do we lean towards left when the bus moves along a curved road to right.

What makes you think this is the absolute way to see the situation?When the entire world moves to the right and you stay in place

LostConjugate said:You would need to lean to the right to keep from falling over...
thecow99 said:I had to think about it, but you're right. If you leaned to the left, wouldn't you fall outta your seat?

Not always. Consider free fall under gravity. You don't feel any force.The question is why do you feel a force when you accelerate

You will feel it, if its not a volume force(a beautiful term I saw in the Fundamentals Of Physics book by Resnick, Halliday).

What? Care to explain what you have posted?LostConjugate said:You are not accelerating in free fall however. You are only accelerating when you are on the ground.

Near the surface of the Earth, an object in free fall in a vacuum will accelerate at approximately 9.8 m/s2, independent of its mass
Gravity isn't getting canceled here. A mass m under free fall near Earth is subjected to a force of mg.It is not taking into account the cancellation of gravity
Mass per se does not *resist* acceleration. However huge an object might be and however negligible a force might be, the object will suffer a non-zero infinitesimal acceleration.Mass resists acceleration, we have mass, so we feel this resistance.

Its a little like filling a container. Have one with a huge base? a given quantity of water will produce only a small increase in level. Small base? The same quantity of water will produce a significant increase in level. That doesn't mean the base factor is *resisting* the water filling process. There will inevitably be an increase in level, however small.
It rather *damps* the increase in the level.LostConjugate said:A larger base resists the rise of the water level.
This isn't a logical statement. The definition of acceleration doesn't include constraints of organs pressing against our lungs.Since your organs are not pressed against your lungs you are not accelerating downward.

This apparent "force" is what you are working against when you lean "into" the turn.

1. Is leaning towards left a natural human tendency?
Research suggests that yes, leaning towards left is a natural human tendency. This is due to the brain's lateralization, where the left hemisphere controls the right side of the body and vice versa. This leads to a preference for using the right side of the body, hence leaning towards left.
2. Are there any evolutionary reasons for leaning towards left?
There are several theories that suggest an evolutionary reason for leaning towards left. Some researchers propose that it may have helped early humans to hold infants with the left arm while performing tasks with the right hand. Others suggest that it may have been beneficial for right-handed individuals to keep their dominant hand free for activities such as hunting or fighting.
3. Can cultural factors influence leaning towards left?
While the tendency to lean towards left may be natural, cultural factors can also play a role. In some cultures, it is customary to carry infants on the left hip, leading to a preference for leaning towards left. Additionally, certain sports or activities may also require individuals to lean towards left, leading to a cultural influence on this tendency.
4. Does leaning towards left have any impact on cognitive abilities?
Several studies have found a link between leaning towards left and enhanced cognitive abilities, particularly in tasks related to language and speech. This is because the left hemisphere of the brain is associated with these functions. However, more research is needed to fully understand the connection between leaning towards left and cognitive abilities.
5. Can leaning towards left be changed or reversed?
While it may be difficult to change a natural tendency, it is possible to consciously train oneself to lean towards the right. This can be done through various exercises and activities that require the use of the left side of the body. However, the extent to which this can be changed may vary for each individual.
