    Idea for "science fair" project?

    Hey MHF. On the 23rd I am to present a real-life functional project that in some clever way, utilizes Newton's laws. I must deliver it completely with calculations.

    Does anyone have any good ideas for such a project?

    Thanks.

    For starters, do you know Newton's Laws?

    Good idea.

    Newton's first law: All objects in motion, stay in motion (at the exact same velocity/acceleration) unless a force acts on them. Same applies to an object in rest.

    Newton's second law: F=MA. The force of an object can be described as its mass times its acceleration.

    Newton's third law: Any action has an identical reaction. Any force applied on an object has an identical force in the opposite direction.

    OK, just because I have a mind that prefers to make up its own movie when it's bored, I'd put myself in the shoes of a hitman/hired goon. You could think about how if you want to cause harm to a person, you can either hit them with something big and heavy (such as a brick), or hit them with something small moving very fast (like a bullet shot from a gun). Then you can list a few different ways you could hurt/kill someone, because the force applied to the object would be great either from the higher mass or higher acceleration...

    Lol thanks. But I need to make some sort of device or something to demonstrate my case. I don't think they'll allow a gun in the classroom.

    Take a pendulum and put on the ground(on the floor) in resting position

    Apply a force on it

    After that show how the pendulum applied the same force on your hand...

    I wish you'd said that to start with. I thought you could actually WRITE some things, provide diagrams etc...

    I ended up swinging a bucket...It's not such a bad experiment, really.
