![]() Of mass M continuously? the answer is that, the mass M will start Will continue to move with constant velocity.īut what will happen if we apply same constant force on a body If the table is frictionless then the ball If a force F is applied at certain instant of time only say t=0 Here I will be explaining the reason why F=ma and I will alsoĮxplain how newton thought and after performing experiments came upĬonsider a mass M placed in ideal system i.e. Some really serious questions that student should ask and try to Mass and acceleration square (F=ma2) or why not F=m3 a. But this mathematical definition is not enough toĮxplain the reasons why F=ma. force equals to the product of mass andĪcceleration. $$S_1=a_1\times m_1 \text$$ where $m$ is the inertial mass of the object identical with $k'$ above.We study in our high schools about Newton second law which ![]() If you multiply the two masses by its corresponding acceleration you find something 1 $S_1$ and something 2 $S_2$, that is: That is you shot two arrows exactly the same.Īs you can see the acceleration $a_2$ of the bigger mass is less that $a_1$ the one of the smaller one. Now you repeat the experiments with two balls of different masses, $m_1$ and $m_2$. ![]() Now you look for a Weight scale and you find the mass of the ball: The ball will keep moving forever.Ģ.) Now suppose that the ball is not moving and you shot this arrow to move it, you have the same conditions as before:Īs you can see the ball wasn't moving and now it is moving, so it accelerated. Something like this will happen Video of ball over ice. What we find is that if we are in a place where the ball is not interacting with anything (air, gravity, etc.). Like this:ī) If you happen to find a ball that is moving with constant velocity, that is it moves in a straight line and it moves equal distances in equal times. Well it's going to stay like that if we are in a place where the ball is not interacting with anything (air, gravity, etc.). ![]() Suppose that you were to perform the following experiments:Ī) You happen to find a ball that is not moving. ![]()
