Inertia or Impulse: Which Explains the Phenomenon?

In summary, people are having heated arguments about the phenomenon of running a short distance after jumping out of a moving bus. This is due to the fact that when you jump out of a moving bus, you are still moving at the same speed as the bus. This is because of the principle of inertia, which states that an object will remain at a constant velocity unless acted upon by an outside force. Therefore, when you land, you need a short distance to brake and slow down gradually, rather than stopping abruptly and potentially getting hurt. This can also be explained by Newton's laws of motion, particularly the law of inertia.

hi...

a basic question... [ ppl are having heated arguments over this at home ]

" when u jump out of a moving bus... u run a little distance"

why we do this? what is this phenomenon?

Before you jump, you are moving at the same speed as the bus.

When you jump off, this does not immediately change. While in the air, you are still moving in the same direction as the bus even though you are also falling towards the ground.

When you land, you still need a short distance for braking, just as if you want to stop while running.

Clear enough?

It's just deceleration. You want to slow down over as long a time as possible. You could always do like my sister and grab a hard object to stop you right away. Hurts, though.

Dear Calculus probably you could say that is an impulse because your momentum is
changing with respect to the bus but i am sorry is not an impulse an impulse will be
if the bus would stop suddenly and your body will be ejected from the bus
and i don't think is inertia either because you see you are just jumping from the bus
the force of the bus is not acting on you. Inertia is the property of an object to remain at constant velocity unless acted upon by an outside force

calculos am sorry my mistake absolutely this force will be inertia

you see when yo jump from the moving bus your body runs a little bit forward because
you have a little bit of the bus momentum and that applies to the law of Newton
the law of inertia
 

FAQ: Inertia or Impulse: Which Explains the Phenomenon?

What is inertia?

Inertia is the tendency of an object to resist changes in its state of motion. This means that an object at rest will remain at rest, and an object in motion will continue to move in a straight line at a constant speed, unless acted upon by an external force.

What is impulse?

Impulse is the change in momentum of an object, which is equal to the force applied to the object multiplied by the time over which the force is applied. It can also be thought of as the amount of force applied over a certain period of time.

Which phenomenon does inertia explain?

Inertia explains the tendency of an object to resist changes in its state of motion. It is the reason why objects continue to move at a constant speed in a straight line, or remain at rest, unless acted upon by an external force.

Which phenomenon does impulse explain?

Impulse explains the change in an object's momentum. When a force is applied to an object, it causes a change in its motion, either by increasing or decreasing its speed or changing its direction. This change in momentum is due to the impulse of the force.

Which concept is more useful in explaining real-world situations?

Both inertia and impulse are important concepts in explaining real-world situations. Inertia is useful in explaining why objects behave the way they do, while impulse is useful in understanding the effects of forces on objects. They are both necessary in fully understanding and analyzing the motion of objects in the real world.
