Newton's Laws help us understand how machines work in our everyday lives, but using these laws can sometimes be tricky.

1. Inertia and Starting Movement:

   • Inertia means an object doesn't want to change its state. This can make it hard for machines to start moving because of resistance.
   • Solution: Use materials that create less friction.

2. Balancing Forces:

   • Figuring out the total forces acting on complicated machines can be a lot to handle.
   • Solution: Try using computer simulations to make these calculations easier.

3. Action and Reaction Forces:

   • When machines use force, they create reactions that can make them unstable.
   • Solution: Use better systems to control the movements.

In summary, even with these challenges, using Newton's Laws can help us design machines that work better if we take it step by step.
