Which object is being acted on by balanced

forces?

• a skateboard that rolls increasingly faster down

  a hill

• a snowflake that falls and lands on a roof

• a car that moves at a constant speed in one

  direction

• a baseball that rolls to a stop in a field

Megan left her wagon outside while it was raining

and it filled with water. When Megan tried to

move the wagon that afternoon, she failed to

budge the wagon. Why did Megan's wagon

become hard to move?

• The rainwater decreased the force of gravity

  pushing on the wagon, increasing the force

  needed to move it.

• The rainwater decreased the force of friction

  pulling on the wagon, decreasing the force

  needed to move it.

• The rainwater increased the mass of the wagon,

  increasing the amount of force needed to move

  it.

• The rainwater increased the mass of the wagon,

  decreasing the amount of force needed to move

  it.

A ball is dropped from the top of a tall building. As the ball falls, the upward force of drag becomes equal to the downward pull of gravity. When these two forces become equal in magnitude, the ball will

• flatten due to the forces.

• fall at a constant speed.

• continue to speed up

• slow to a stop.
