The invention discloses a teaching educational toy in accord with Newton's second law. accelerated speed number values are marked on an accelerated speed marking baseboard; one side of the low number value of the accelerated speed marking baseboard is provided with a mass bracing rod, a mass notice board is arranged on the mass bracing piece for prompt, and a mass ball is arranged on the mass bracing rod; one side of the high number value of the accelerated speed marking baseboard is provided with an accelerated speed notice baseboard, a lifting rod is arranged at the outer side of the accelerated speed notice baseboard, lifting rod teeth is arranged at the outer side of the lifting rod from top to bottom, and a teeth head of the lifting rod teen is downward; a lifting wheel shaft is placed in a lifting rod teeth socket of the lifting rod, and the lifting wheel shaft is fixed to a lifting wheel at the outer periphery of the lifting wheel shaft; a lifting wheel clamp is arranged at the top end of the lifting rod, and the lifting wheel clamp can clamp the lifting wheel to fix the height of the lifting rod. The teaching educational toy in accord with Newton's second law can let children study physical knowledge in entertainment by comparing and verifying the Newton's second law through calculated number values of data and theory drawn from experiments.
Description
technical field [0001] The invention relates to a device in the field of toys, in particular to an educational toy for teaching Newton's second law that allows children to learn physics knowledge during entertainment. Background technique [0002] Newton's second law states that momentum is The mass point, in the external force Under the action of , the rate of change of its momentum with time is proportional to the external force on the particle, and is in the same direction as the external force; the formula is expressed as: [0003] [0004] According to the definition of momentum, [0005] [0006] If the mass of the particle does not change with time (ie ), then the magnitude of the acceleration of the particle motion is proportional to the magnitude of the external force acting on the particle, and the direction of the acceleration is the same as that of the external force; expressed as: [0007] [0008] In layman's terms, Newton's second law states th...
