Understanding Dot Diagrams in Physics

What does it mean when the dots in a dot diagram are equally spaced?

• The object is accelerating.

• The object is moving at a constant speed.

• The object is decelerating.

• The object is at rest.

How can you identify a leftward moving object in a dot diagram?

• The first dot is on the left and the last dot is on the right.

• The dots are equally spaced.

• The dots are clustered together.

• The first dot is on the right and the last dot is on the left.

What is the direction of the velocity vector for a falling object?

• Rightward

• Leftward

• Downward

• Upward

If an object is slowing down while moving upward, what is the direction of its acceleration?

• Rightward

• Leftward

• Upward

• Downward

When an object is speeding up, how does the direction of its acceleration compare to its velocity?

• The acceleration is always upward.

• They are in opposite directions.

• They are in the same direction.

• The acceleration is always downward.
