How is your weight different on Earth and on the moon?

• You weigh more on Earth because the force of attraction is weaker.

• You weigh less on Earth because the force of attraction is weaker.

• You weigh the same because the force of attraction is equal.

• You weigh more on Earth because the force of attraction is stronger.

If the slope of a position vs. time graph is negative, what does that imply about the motion of an object.

• The object is moving in the negative direction.

• The object turned around.

• The object has a negative acceleration.

• all of the above

What does the slope of a velocity-time graph reveal about an object's motion?

• the acceleration of the object

• none of the above are revealed

• the velocity of the object

• the object's change in position over time

A position vs. time graph goes from a positive slope to a negative slope. What did the object do to cause this?

• The object changed the direction of its motion.

• The object stopped moving.

• The object increased its speed.

• The object decreased its speed.
