Making a speed mouse trap car involves extracting the most energy you can from the mousetrap spring in a short distance. The lever arm needs to be shorter than the distance car's because the shorter the arm is, the quicker the spring will snap, and thus more torque gets extracted from the spring. Se mer A mousetrap car is a small vehicle whose only source of motive power is a mousetrap. Variations include the use of multiple traps, or very big rat traps, for added power. Mousetrap cars are … Se mer The general style for a mousetrap car varies. A number of commercial vendors offer plans, kits and complete cars for sale. In addition to mousetrap cars, contests have been created for mousetrap boats. and mousetrap airplanes.

The formula for the energy of motion is: KE=0.5\times m\times v^2 K E = 0.5×m ×v2. where KE is kinetic energy in joules, m is mass in kilograms and v is velocity in meters per second. 00:03 12:50. greystone village salisbury nc

Using subscripts 1 and 2 to represent initial and final energy, this law is expressed as. K E 1 + P E 1 = K E 2 + P E 2. Either side equals the total mechanical energy. NettetThis unit is made up of two main topics called electricity and magnetism. It treats magnetism first and then electricity. Magnetism deals with the properties of a magnet while electricity deals with the properties of electrons at rest and in motion.
