A wooden cube is 1 inch long on each side. How many form a cube 2 inches along each edge?
Two, because a 2-inch cube is twice as big as a 1-inch cube.
Eight. Two cubes make a tower. For a cube, you need two layers of 4.
A ball rolls down a spiral track. The end of the track curves left. What path does the ball take when it comes off the track?
It curves, because an object keeps going in the same direction.
A straight line to the left. Only objects acted on by a constant lateral force curve.
If you drop one bullet off a table 3 feet high, and fire another one straight across an empty football field, which bits the ground first?
The dropped bullet lands first because it has only three feet to travel.
Both bullets hit at the same time: downward velocity is independent of horizontal velocity.
