• Constant speed

• stopping

• decreasing speed

• deceleration

Which of these accurately describes the motion of the toy train?

• The toy train speeds up while going forward and then slows down

• The toy train slows down while going forward and the moves backwards.

• The toy train moves forward at a constant speed , slows down, and then stops.

• The toy train moves forward at in increasing speed, stops, and then moves forward.

This line shows that:

• the bus is at a bus stop

• the bus is gradually slowing down (decelerating)

• the bus moves in a steady speed

• the bus is gradually speeding up (accelerating)

This line is:

• curved

• vertical

• horizontal

• none of these
