Newton's second law of motion is

Concept:

Isaac Newton:

• Isaac Newton was born in Woolsthorpe, England in 1642.
• He enunciated the three laws of motion and the universal law of gravitation.

Explanation:

Law of acceleration:

• The second law of motion or acceleration states that the rate of change of momentum of an object is proportional to the applied unbalanced force in the direction of the force.
• That shows force is proportional to the product of mass m and acceleration a.
• In SI unit force is one that causes an acceleration of 1 m s-2 to a mass of 1 kg.

Thus, Newton's second law of motion is the law of acceleration.

Additional InformationFirst law of motion:

• An object continues to be in a state of rest or of uniform motion along a straight line unless acted upon by an unbalanced force.

Third law of motion:

• To every action, there is an equal and opposite reaction and they act on two different bodies.
