The driver of the motorcycle is thrown in the air because he was in motion until the bike hit the barrier. All objects in motion stay in motion.

Newton's 2nd Law of Motion

Newton’s 2nd Law of Motion: acceleration of an object is in the same direction that the net force is applied on the object

  • F=ma Force = mass x acceleration a=F/m

The box below has a mass of 5 kg and an acceleration of 4m/s. Force equals mass times acceleration so you simply multiply to get 20N for the force.

Newton's 3rd Law of Motion

Newton’s 3rd Law of Motion: for every action there is an equal and opposite reaction

The shoe is pushing on the ground and the ground is pushing on the shoe which is an equal and opposite reaction.
