Newton’s 2nd and 3rd Laws Of Motion
2nd law: F=ma
Newton’s second law of motion helps clarify the
behavior of objects where the forces are not balanced. If the forces are unbalanced then one of the
objects has to have acceleration. The
law states that the net force is equal to the mass of the object times the
acceleration of which it is moving. The
3rd law of motion states that for every action there is an equal and
opposite reaction. For a car going down
the street there is the force of friction that is opposing the direction the
car is going. If the car is not able to
overcome this force of friction then it will not go anywhere. A good example of the 3rd law of
motion is someone stepping out of a boat towards the shore. The boat will want to move away from the
shore while the person stepping out of it will be going towards the shore. If the person is not out of the boat soon
enough then he/she will most likely get wet.
