Thank you Bob. I was wondering how long would 2 D cells last?

umm the one you listed as a spool how would i be able to find both ends? and how many 2d batteries should i put in series? i can buy one off local store which is 0.683433013 in a spool would it be sufficient?

I need to a pull a magnetic ball 15cm away; ball is 1 cm in radius. What type of power should I use? 9V battery would be sufficient? what else can we use?

Well I need to create a reasonably powerful electromagnet and I am in Gr. 12. I havn't been able to find a proper guide/book to create a electromagnet. I plan on using a ferrous core and 38 gauge wire. I am going to wind the wire around a spool. My questions: What should be the diameter and...

I wanted to know if copper wire is the best for coil and for a core wire hangers. 9v would be sufficient?

I have attached a preliminary sketch of the project but my questions is would the electromagnet be able to attract the metal ball in motion? This would include: Springs Ramps Circular Motion Light (Refraction) Projectile Electricity Magnetism Forces Transfer of Energy

i was just wondering umm would the car have enough energy to hit the lever so the pulley can operate with the electric motor...?

what type of concepts would it implement? I can see springs, ramps, circular motion, pulleys, transfer of energy...

a spring?

a lever would launch the catapult, i was thinking maybe i can pull the lever by using a pulley and a mass?

hmm...?

well i was thinking of building a catapult but that is just transfer of energy. projectile and levers.

Hello, I am in Grade 12 physics class and I have been given a open ended project; where we are required to build/create a machine which would involve at least 6 of the physics concepts: ramps, pulleys, levers, transfer of momentum/energy, projectile motion, circular motion, stored elastic...
