Describe Newton's second law.

Newton's second law, F=ma, describes the relationship between an external force on an object F, the mass of the object m and the resulting acceleration of the object a. We can see that the acceleration of the object is proportional to the force acting on the object. This means that if the force on the object is doubled, the acceleration will also double.
