Newton's second law states that the acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass. In simpler terms, the greater the force applied to an object, the greater its acceleration will be. Similarly, the larger the mass of an object, the smaller its acceleration will be.
The formula for Newton's second law is F = ma, where F represents the net force, m represents the mass of the object, and a represents the acceleration.
In words, Newton's second law can be written as "The acceleration of an object is equal to the net force acting on it divided by its mass."
Yes, Newton's second law can be applied to both linear and rotational motion. In rotational motion, the equation is τ = Iα, where τ represents the torque, I represents the moment of inertia, and α represents the angular acceleration.
The units for force in Newton's second law are Newtons (N), mass is measured in kilograms (kg), and acceleration is measured in meters per second squared (m/s^2). For rotational motion, torque is measured in Newton-meters (Nm), and moment of inertia is measured in kilogram-meters squared (kg-m^2).
