Two model trains are running on tracks that are lined up next to each other. The two trains are not moving at the same speed. What would cause one train to move faster than the other?

• The slower train's cars have less mass.

• The faster train has more energy.

• The faster train has a wider track.

• The slower train has an older engine.

When we observe the moving object moving more slowly, we know that it –

• will move in a new direction.

• has more gravity pulling on it.

• can’t go back to where it started.

• has less energy than it had before.
