a change in position is defined as

• force
• motion
• speed
• acceleration

How are speed and velocity different?

• Speed includes direction
• Speed indicates momentum
• Velocity includes Momentum
• Velocity includes direction

A student slides a book across a desk by giving it an initial push. Which of the following is the MOST important reason that the book eventually comes to a stop instead of continuing to slide?

• The initial force was too weak to keep the book in motion.
• The mass of the book was not enough to keep the book in motion.
• The force that occurs when the book rubs against the desk stops the book.
• The magnetic force from the Earth stops the book.
