According to Newton's second law of motion, acceleration is proportional to what?

According to Newton's second law of motion, acceleration is proportional to the resultant force acting on an object. This is succinctly expressed in the equation F = ma, where F represents the total force applied to the object, m is the object's mass, and a is the acceleration that results from that force.

The law indicates that for a given mass, the acceleration of that object increases with an increase in the net force applied. This relationship highlights that when a greater force is applied to an object, it experiences a greater acceleration, assuming its mass remains constant.

While mass does influence how much acceleration is produced for a given force, acceleration itself is specifically proportional to the resultant force. Speed of motion and friction represent other factors in motion dynamics but do not define the direct relationship of acceleration as described by Newton's second law.
