While driving down the road, a firefly strikes the windshield of a bus and makes a quite obvious mess in front of the face of the driver. This is a clear case of Newton's third law of motion. The firefly hit the bus and the bus hits the firefly. Which of the two forces is greater: the force on the firefly or the force on the bus?

• The Bus

• The Firefly

• The same force is applied

• law of gravity 
• Newtons 4th law 
• Newtons 2nd law
