Braking reduces speed.
effect of force
is move themselves
A liquid becomes a solid when heat is removed. The energy content decreases, and the speed of the particles decrease.
the faster the speed of the bicycle,the brighter the lamp
The average bicycle speed is around 15-20 km/h.
The speed of the motor vehicle is gently slowed down. The more aggressive the brakes are applied the faster the vehicle slows down eventually coming to a full stop.
It accelerates as long as the force is applied, and after that it continues at a uniform speed and direction.
When an object exceeds the speed of sound, it creates a sonic boom, which is a loud noise caused by the shock waves produced as it breaks the sound barrier.
The standard chain width for a 9-speed bicycle chain is 6.6mm.
Speed does not break down atoms in itself, but high speed collisions do, and that happens at very high temperatures, because temperature is random motion on a sub-microscopic scale.
The speed ratio of a bicycle is the (gear ratio* radius of the wheel)/ Length of the pedal arm.
Mark Cavendish's top speed on a bicycle is around 45-50 miles per hour.
