Intended for ages 1-5 years; each car requires 2 AAA batteries; batteries included for demo purposes only; new batteries recommended for regular use.

Smart Wheels™ playsets. Simply roll the race car over one of the playset's SmartPoints™ to see the race car's light flash and to hear greetings, fun sounds, short tunes and sing-along songs (each playset sold separately).

Itself. They also play music and sounds as well as three songs for your child to sing along. To VTech gogo smart wheels promote language motor skills and imaginative. Play.

VTech is a world leader in age-appropriate and developmental stage-based electronic learning products for children.

VTech toys encourage fine motor skill development. Many movements babies make are in preparation for the next stage of their development.

As the axle rotates. The wheel moves of greater distance than the axle. So it increases the speed. But it also turns with less force.

Water gravel grass or a thin coating of sand. And limits torque to wheels to prevent slippage.

Benefits of VTEC Engine Due to the VTEC technology, as the power is passing through the intake valve and through the exhaust valve, less fuel is burned in order to give your car a power push through normal driving. This can lead to much lower fuel consumption.

As revs climb, the computer directs oil flow (A) through the rocker shaft. This slides a pin (B) that locks the low-rpm rocker arms (C) acting on each cylinder's two intake valves to a high-rpm rocker (D). That third rocker follows a different cam profile optimized for higher engine speeds.

First, transport: the wheel began to be used on carts and battle chariots. Second, and more importantly, it contributed to the mechanisation of agriculture (animal traction, crop irrigation) and craft industries (for example, the centrifugal force of the wheel is the basic mechanism in windmills).

It's a simple machine, just like a lever, that allows a small effort over a greater distance do the same work as a larger effort over a smaller distance. Yet the complexities of this simple machine mean that it will no doubt continue to be central to human innovation.

A drive wheel is a wheel of a motor vehicle that transmits force, transforming torque into tractive force from the tires to the road, causing the vehicle to move. The powertrain delivers enough torque to the wheel to overcome stationary forces, resulting in the vehicle moving forwards or backwards.
