Q3. What is theNNewton's 2nd law
Ans. 
Newton's 2nd law states that the acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass.
• F = ma (force equals mass times acceleration)

• Acceleration is in the same direction as the net force

• The greater the force applied to an object, the greater its acceleration

• The greater the mass of an object, the smaller its acceleration for a given force
