Question

explain the relationship
between force,mass and
acceleration

Answer 1

Force = Mass x Acceleration

But the way to look at it is this: a FORCE acts upon an object that has a MASS. The result is an ACCELERATION. It is important to know that FORCE is the cause and ACCELERATION is the effect. The MASS of the object is just an inherent (it is what it is and you can't choose or change it) property of it. (Another example of an inherent property of an object would be what it is made of. If it is wood then it is wood... and you would have to make a new one to make it be made of something else).

So, about how they relate: You choose how much FORCE to use when you push (or pull) on the object. Depending on how much MASS it has, and depending on how hard you push/pull, the ACCELERATION will chance. You push hard on a small object, it gets moving really quickly. You push the same on a much larger object, and it gets moving (accelerates) slower. Eventually you may make them move at the same speed... but the bigger (more massive) one takes longer to get there.. and that is acceleration.

Answer 2

Force is proportional to accelerations with a constant of proporcionality being the mass.
