Elementary math teachers know the importance of this model in teaching the concept of applying distributive property in area model.
The idea is to break one large area (which represents the product of two numbers) into several pieces (products of smaller numbers), then to find the areas of the pieces individually, and finally add to get the area of the whole (the product of the given numbers).
These lines portray a tale of creation and vanishing. It describes the creation of a photon, its subsequent disappearance when an electron absorbs it on the cathode plate’s surface, the subsequent departure of the electron from the cathode, and lastly the eventual disappearance of the electron when it reaches the other plate and captured.
Newton’s first law states that when net force is zero, objects at rest remain at rest and objects in motion continue at constant velocity. This experiment uses an air cushion scooter to eliminate friction, demonstrating that with zero net force (weight balanced by track reaction), the scooter remains stationary when at rest and continues moving at constant speed when given an initial push, until an external force stops it.
Inertia is the property of matter that resists changes in velocity. When a car brakes, your body leans forward; when it accelerates, you lean backward – both demonstrate inertia in action. The greater your body’s mass, the more pronounced this effect. Inertia encompasses resistance to changes in both speed and direction of motion, making it a fundamental concept in understanding how objects behave.
This is a new simulation of a rotating disk being illuminated by a stroboscope. You can control the speed of the disk and the frequency of the stroboscope, and see how the white spot on the disk appears. You can check all the cases of stationary appearance and the slow-motion appearance.
تُظهر هذه التجربة في انعدام الجاذبية على متن مكوك فضائي قانون نيوتن الثاني. بدون قوة الجاذبية، يطبق رائد الفضاء نفس القوة على كرات ذات كتل مختلفة. تتسارع الكرة الأخف أكثر من الأثقل، مما يثبت العلاقة العكسية بين الكتلة والتسارع عندما تكون القوة ثابتة (القوة = الكتلة × التسارع). عرض مثالي لمبادئ الفيزياء الأساسية في ظروف الجاذبية الصغرى.
If you or your student or child are having difficulties in learning long division, then you will find this simulation comprehensive and instructional, that guides the learner through the process step by step. This application is for long division with float quotient. Another application on long division with remainder is also available in the simulations section.
