Choose from 8 wooden cars and let the racing begin! Children can pick their favourite car and release the cars at the top of the SEVEN-Level Inertia Track to watch the cars travel down 7 layers of track! This is the tallest track set unit ever built, as the track measures 16.14 inches TALL!
Each car flips at the end of a ramp to continue to the next. FLIPPING AND SPEEDING down SEVEN layers of tracks, kids will love the excitement this set brings.
The ramp and cars are made of robust wood and plastic materials, making them compact and sturdy.
With this educational toy - 7-Level Inertia Track - kids can learn how the cars are able to move swiftly down the levels and are able to keep moving due to the law of inertia!
The Law of Motion and Inertia
Law of Motion - an object will remain at rest or move at a constant speed in a straight line unless it is acted on by an unbalanced force.
Inertia is the tendency of an object to stay at rest or in motion. Inertia is the property of an object that resists changes in its motion. Because of inertia, an object at rest tends to stay at rest. An object in motion tends to keep moving at a constant speed in a straight line.
According to Newton's First Law of Motion, because the cars have built up speed from the decline of the first ramp, this "unbalanced force" continues along the other 6 inclined ramps. Inertia helps to keep these cars in motion as they can be considered low mass objects and when put in motion, can continue to move.
To understand inertia, imagine trying to move a bowling ball and a golf ball that are at rest.
Bowling Ball Mass = 5kg Golf Ball Mass = 0.05 kg
[The bowling ball has 100 times more mass than the golf ball, so it has 100 times more inertia}
Which needs more force to start moving? If you push for the same distance, the bowling ball requires much more force to get it moving the same speed as the golf ball. The bowling ball requires more force because a bowling ball has more inertia than a golf ball. The greater an object's inertia, the greater the force needed to change its motion.
*We always recommend adult supervision when playing as there are small parts (cars are 1 1/2" long and 1" wide) - especially those under 36 months, to be closely supervised when playing
