There's less friction on ice than on concrete, so on ice you'd have to brake real carefully or the bike would begin to slide or skid.
It is easier to stop a bicycle than a car with the same speed because the bicycle has less mass and momentum compared to the car. The car's greater mass and momentum make it harder to stop quickly. The car's brakes also have to work against greater inertia, requiring more force and distance to stop.
Bicycles don't build up as much inertia, because they have less mass, and are also usually moving slower than cars. the heavier and faster something is the longer it takes to stop.
A bike-and-ride is the act of using a bicycle in conjunction with another type of transportation such as public transport, a system which ordinarily involves bicycle storage, and the ability to travel from stop to stop on their bicycle.
THe brakes rarely need to stop. But the brakes can be used to make the bike stop.
No way you have got to be kiding me everybody I know, knows the answer to that so here is the answer a BICYCLE!!!!!!!
inertia
Long pull brake levers on a bicycle provide increased leverage and better braking power, making it easier to stop quickly and safely. They also offer improved control and comfort for the rider, especially when riding in challenging conditions or on rough terrain.
Concrete is a common material used to shield against radiation. The amount of concrete needed to effectively stop radiation depends on the type and intensity of the radiation. Thicker layers of concrete provide better protection against radiation. Generally, a thickness of at least several feet of concrete is needed to effectively stop most types of radiation.
It is your momentum of moving forward that has to be overcome before your brakes can bring the bicycle to a stop.
A concrete parking stop typically weighs around 100-200 pounds, depending on its size and design.
Concrete is made of a mixture of cement, aggregate (small stones), fine aggregate (sand), water and other chemical additives. When mixed the wet concrete will remain so for Most people assume that set concrete has no water in it, this is not so, as the water content helps bond the aggregates and cement, this process is known as Hydration. Concrete with no water in it would crumble to dust. Adding more water to the mix will make a concrete that is easier to work, while less water will produce a stronger, more durable concrete. After initial setting of the concrete, a slow amount of water loss is expected due to the concrete drying, it can take anything up to a year for water to stop evaporating slowly out of the concrete. So for this reason the answer to your question is yes, dry, set concrete will weigh less than wet concrete, but for anything up to a year it will keep getting lighter, due to waterloss.
The physical size doesn't matter. The ability to stop (or start) an object depends on its mass. For example, a bowling ball has more mass than a large balloon or sofa cushion. Smaller masses are easier to stop (or start).
