Why do you fall i the forward direction when a moving bus brakes to a stop and fall backwards when it accelerates from rest?

because the bus still moving its uniform motion suddenly the bus applies brakes the bus stop at rest so we fall forward due to inertia and the bus was its rest suddenly the bus starts its accelerates so we fall backwards due to inertia

∙ 8y agoIt's a demonstration of the property of matter called inertia; i.e. as stated in Newton's First Law of Motion: an object at rest tends to remain at rest and an object in motion tends to remain in motion unless acted on by an outside force.
In actuality the person isn't really falling backward. What's happening is that different parts of their body are all moving forward - but at different rates with respect to the ground outside of the bus.
When the bus starts to move its speed increases, i.e. it accelerates. The person's feet are held in place by friction between their shoes and the bus floor so they move in tandem with that acceleration. However inertia causes their upper body to try to stay where it was rather than moving forward at the same rate as their feet. Because our bodies are somewhat flexible the net result is that the person's feet move forward faster than their upper body. In effect the bus is pulling their feet out from under them in a forward direction.
The reason a person on the bus thinks they're falling backwards is that they're determining their position by looking at the bus itself. If the bus is moving forward faster than their chest and head, their upper body is moving backwards relative to the position of the bus (and their feet!) On the other hand, someone standing on solid ground outside of the bus would see both the bus and the person move forward relative to the ground, but the person's upper body would move more slowly than the bus.
A person sitting on an accelerating bus experiences similar forces, but the seat pushes their upper body forward at the same rate as their feet and prevents them from losing their balance.

Acceleration is against the direction of motion?
suppose when we apply brakes to a car in motion then the speed of the car decreases which means the acceleration is backwards but the car is still running in the forward direction
Which law applies when a person is thrown forward in a bus when the brakes are suddenly pressed?
law of inertia
What is a sentence using inertia?
'The car's inertia carried it forward several feet after the driver pushed the brakes.
What is an example of a sentence using the word 'inertia'?
'The car's inertia carried it forward several feet after the driver pushed the brakes.' 'His inertia launched him forward after reaching the base of the hill.'
Why do keep moving forward when you slam on the brakes on your bicycle?
Because when you brake, the brakes stop the wheels from moving. But that doesn't stop the bike from moving. It means that the speed/force/velocity at which you were traveling was forceful enough to override the brakes. So basically, you're sliding.

Sharon cruises east at 5 ms she then uses her brakes and comes to a gentle stop as Sharon slows how does the direction of the net force compare to that of her motion?
An object will accelerate in the direction of the net force acting upon it. While she is traveling at a consant speed, the forces due to friction, wind resistance, and so forth are countered by the equal-in-strength but opposing force of the engine. When she applies the brakes, the engine is no longer pushing, so there is a net force in the opposite direction of her motion. This net force accelerates her in the opposite direction of her motion -- we call this deceleration. So, long story short, the direction of the net force is opposite to the direction of her original motion (backwards).
Brakes work going backwards better than going forwards?
If your brakes work going backwards better than forwards, you should replace your front brakes. You can get your rotors turned to save time, as well.
What are 3 situations that would explain the law of inertia?
When a car accelerates. Your body wants to stay stationary, therefore when the car starts accelerating you are pushed into your seat until the car stays at a constant speed and you catch up to the speed.When a car brakes. Your body wants to keep moving forward as it was before decelerating began, you move forward but the friction between you and the seat stops you from falling off.When a car turns. Your body wants to keep going forward in a straight line but turning makes you go in a different direction and you lean.
Why do you keep moving forward when you slam on your brakes on a bicycle?
It is your momentum of moving forward that has to be overcome before your brakes can bring the bicycle to a stop.
What would cause the rear tires to make a clicking noise and have a grabbing feeling when the brakes are gently applied from a stand still position to moving forward or backwards on a 2004 Isuzu Rodeo?
Check ABS system.
What causes the feeling of being pushed in a car when the car accelerates?
It's called inertia, and it means that stuff resist change. Braking your body has gotten used to travelling forward, so when the car brakes you get thrown forward. If you're standing still your body has gotten used to that too, so when the car takes off you get pushed into the seat.
What is Newton's First Law of MotionGive the example of the law to help illustrate your point?
If you are in a fast moving car and the brakes are applied suddenly and hard, your body will continue moving in the forward direction.
Why do you move forward when your car brakes suddenly?
Inertia
What is a fixie bike?
Fixie bike are bikes (usually road bike frames) that have a fixed rear sprocket which allows you to pedal forward like normal, but does not allow you to just coast . If you pedal backwards it goes backwards if you pedal slow it will remain slow. The whole point of a fixie is to eliminate brakes shifters to simplify a road bike.
Who is at fault in IL if you are both are stopped at a intersection and the car in front of you accelerates to merge onto the intersection than slams on the brakes and you hit him?
you. you hit him.
