Ok so if we now consider a forklift truck with a load on its front, if the load is lifted at constant velocity, no added load on the tyres but if the load was accelerated then the tyres would be compressed as long as the acceleration was happening?

Yes but what weight does the object need to be to observe that as you push upwards against it, the force goes through your feet and the scales register an increase?

I am not fully sure that this applies when physiology is involved, I think the force may somehow be absorbed into the lifting muscles.

To every force there is an equal and opposite reaction?

Ok thank you ,:) tell me this got me thinking... Imagine I have a heavy weight balanced on my head and I want to lift it so I push it up... But it is too heavy to lift... Will the force I am pushing it upwards be felt as increased weight on the scales. Even though it doesn',,t move? Note here I...

My scales were a simple mechanical set

It must accelerate to begin with?

Ok, I was assuming that since force =ma that the weight should go up while the weight is in motion upwards?

if I move a weight upwards, will the force exerted on my feet change? I tried standing on scales and lifting a weight but nothing changed as the force seemed to be all in my arm muscles and no change in the weight on the scales...
