David and Peter were moving a bookshelf across the carpet in their classroom. Even though they pushed as hard as they could, the bookshelf would only move a few inches at a time.   Which of the following best explains what happened as they tried to push the bookshelf? 

• The force of gravity opposed the motion of the bookshelf. 
• The force of friction opposed the motion of the bookshelf. 
• When they tried to push the bookshelf, air resistance acted against them. 
• When they pushed the bookshelf, the bookshelf pushed back with an equal and opposite force. 

Will and Tammy are moving a dresser. They are arguing about which direction to move it. Will is pushing the dresser with a force of 5 newtons towards Tammy. Tammy is pushing the dresser towards Will with a force of 10 newtons. What happens to the dresser?

• Her mother's car is traveling at a greater speed than her father's car. 
• Both cars are traveling at the same speed since they travel the same distance.
