Final answer:
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 for linear motion, while for angular motion, the torque on an object is equal to the product of its moment of inertia and angular acceleration.
Step-by-step explanation:
Newton's 2nd law for linear motion states that the acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass. This can be represented by the equation: F = ma, where F is the net force, m is the mass, and a is the acceleration. An example of this is when you push a heavy box on the floor with a certain force, the box will experience a smaller acceleration compared to a lighter box pushed with the same force.
Newton's 2nd law for angular motion states that the torque acting on an object is equal to the product of its moment of inertia and its angular acceleration. The equation is given as: τ = Iα, where τ is the torque, I is the moment of inertia, and α is the angular acceleration. For example, if you apply a torque to a spinning wheel, the wheel's angular acceleration will depend on the torque applied and the moment of inertia of the wheel.
