Experiment on Newtons First Law

[spikehoward]

Main Question or Discussion Point

I am wondering if anyone knows of a good resource to see Newtons first law in action. For example, a block being pulled by increasing force until it moves?

Welcome to Physics Forums.

I think stamping your foot on the ground to get snow off is a great example: you put your foot and snow into motion. You apply a net force to stop your foot but not to the snow so it remains in motion, coming off your foot.

The same argument applies to shaking your hands to dry them...and to throwing anything.

The first law is also consistent with things usually staying where you put them.

to see Newtons first law in action

Look up in the (night is best) sky and see the planets and all the rest of the stuff up there, moving and obeying N1 and N2 to a pretty good degree of accuracy.
