WEBNewton's second law tells us exactly how much an object will accelerate for a given net force. a = Σ F m. To be clear, a is the acceleration of the object, Σ F is the net force on the object, and m is the mass of the object. Wait, I thought Newton's second law was F=ma? F = m a Σ F m a. a = Σ F m. m a m a m a.
