Newton's second law of motion states that the net force acting on an object is equal to the product of its mass and the acceleration. Often written as F = ma. Get PHYSICS READY @ https://the-science-cube.teachable.com/

The Newton's second law put another way states that the acceleration a body experiences is proportional to the force being applied. Important to remember that acceleration is a result of force or force cause acceleration. You would never say that acceleration on an abject is resulting in a force.

Force is a vector quantity and has magnitude and direction. It follows the rules of vector algebra. 

Newton's second law of motion
The net force acting on a body is equal to the product of its mass and acceleration
Fnet = m X a

In using the above equation while solving problems, we must isolate the body on which net force is being calculated. Then we should consider only the forces that are acting on the body. Most forces would have a physical touch on the body, barring a few like magnetic force. The vector sum of all these forces would then be the net force on the body.
