AnswerInertia.

Newton's first law tells us that an object in motion tends to stay in motion and an object at rest remains at rest, unless acted upon by an outside force.

This phenomenon is called inertia.

A wheel is designed to turn with little resistance. The surface of a tire on the other hand is designed to have maximum resistance between the tire and the road surface. If designed properly, the wheel allows the vehicle to move with little mechanical effort while the tire provides the necessary contact with the road surface providing the desirable control for steering and braking.

The brakes, of a motor vehicle or bicycle, modify the ability of a wheel to turn freely, and since the wheel will tend to turn less freely, the vehicle will tend to slow.

The inertia of the vehicle or bicycle with respect to the road can be considered to be kinetic energy. When the brakes are applied, the friction between the brake pad and the braking surface produces heat. The produced heat is a direct result of the amount of kinetic energy that is given off by the slowing vehicle.

The change in velocity can never be instant. Change in velocity is measured in ft/sec/sec or M/sec/sec. That phenomenon is called acceleration, and applies to any change in velocity.

These and other physical laws are the subject of high school physics classes and typically require considerable time to fully comprehend.

Why do you keep moving after you slam your brakes on your bike?

Your momentum wants to keep moving forward.


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.


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.


Why do you keep moving foward when you slam on the brakes on your bike?

inertia


Inertia and riding bikes?

When riding a bike, inertia helps to keep the bike moving forward and stabilize it as you pedal. Inertia is the tendency of an object in motion to stay in motion, so when you pedal, your body and the bike have inertia that keeps you moving forward. Turning or stopping the bike requires the application of additional forces to overcome this inertia.


When a driver applies brakes quickly what best explains why a book on the seat keep moving forward?

When a driver applies the brakes quickly, inertia causes the book to continue moving forward momentarily before friction and the force of deceleration from the car's brakes eventually bring it to a stop. The sudden stoppage of the car transfers inertia to the book, causing it to move forward until external forces act upon it.


Why do you keep moving when you slam the brakes on your bicycle?

even though wheels are locked, and not rolling, road friction allows bike to slide until coming to stop


When a person is riding a bicycle and suddenly apply the front brake the back part of the bicycle raises why?

Because of inertia. Stuff that is moving wants to keep moving. When the bike can't go forward, it'll try to topple forward instead.


Make a simple sentence with the word inertia?

The car's inertia caused it to keep moving forward even after the brakes were applied.


What do all bike brakes have in common?

They try to keep the wheels from spinning.


When you ride a bicycle at full speed and the bike stops why do you have to push hard on the handlebars to keep from flying forward?

It's called inertia, or conservation of energy. Basically it means that an object that is moving likes to keep moving, and that an object at rest likes to remain at rest. When you're on the bike you are that moving object that would like to remain moving, so to resist that force you have to brace your arms against the bars. The bike willthen transfer that force through the for and wheel and into the ground.
