The marble run

The marble runWe started to plan our marble run

We started the construction Newtons first law (the law of inertia)An object at rest will remain at rest unless acted on by an unbalanced force. An object in motion continues in motion with the same speed and in the same direction unless acted upon by an unbalanced force.

Newtons second lawThe greater the mass the greater the amount of force need FORCE = MASS x ACCELERATION.

Newtons third lawEvery action has an action that has the same force, but in the opposite direction.
