The train falls back to the tracks because of the force of gravity.
Gravity acts between the train and Earth to pull it down to the tracks.
Gravity acts between the wheels and the track to roll it down.
Gravity is turned back on by a switch and the train falls.
Gravity is increased when needed to stop the train.
What two forces are acting on the glasses?
Friction with the books and lift of the table.
The pulling force of magnetism and air resistance.

Why is it important that structures like a bridge have balanced forces acting on it?
To ensure that the bridge doesn't fall and our drivers can safely cross.
So that the cables hold the bridge up like a person's pants.
To ensure the water stays under the bridge.
To make sure that the bridge be moved to rise above the waves.

The train begins by resting on the track.
balanced forces
unbalanced forces
When the track is turned on, the train starts to rise up off the tracks.
Balanced forces keep the train on the track.
Unbalanced forces allow the magnetic force to overcome gravity and rise.
The electromagnet is turned on and the train is floating above the track.
balanced forces
unbalanced forces
What are the two balanced forces acting on the train to make it float?
Magnetic force is stronger than Earth's gravity making the forces unbalanced.
Magnetic force pushing up is of equal strength to the force of gravity pushing down allowing the train to float.
When the track is turned off, the train starts to gently fall down. Which force becomes stronger?
force of gravity
magnetic force
