Inertia is the resistance of an object to change its motion.
Inertia is (1 point)
• a moving object's speed and direction.
• a force that acts on a resting object.
• the resistance of an object to change its motion.
• an object's motion.

You are sitting in a stopped bus. When the bus starts moving forward, you appear to move backward relative to the bus. Which statement best explains this observation? (1 point)
• The force of inertia on you balances the force from the motion of the bus.
• Inertia prevents the force of the bus from acting on you.
• The motion of the bus creates an unbalanced backward force on you.
• The bus moves forward, while inertia keep you in place.
• The force of inertia on you balances the force from the motion of the bus.
• Inertia prevents the force of the bus from acting on you.
• The motion of the bus creates an unbalanced backward force on you.
• The bus moves forward, while inertia keep you in place.
The statement that best explains the observation is: The bus moves forward, while inertia keeps you in place.
Which statement best explains why a paper airplane eventually falls to the ground? (1 point)
The unbalanced forces of air resistance and gravity slow the airplane and pull it down.
• Inertia acts as a balanced force that slows the airplane and pulls it down.
• Inertia creates the new forces acting on the airplane to keep it up.
• The force from throwing the airplane loses strength as the airplane moves.
