Newtons 2nd law

Newton's second law says that an object will change velocity if its pushed or pulled upon

The explanaion of this is that the acceleration of an object is determined by the size of the net force(object) and the mass of it.

F=ma

F=force(Newtons)

A=accelaration(9.8m/s2)

M=mass(Grams)

Your eveyday a shoe box and a moving box and dropped it off the top of the stairs. The shoe box would fall faster than the moving box because it has a smaller net force. In other words the shoe box has a smaller area which cause it to fall faster than the moving box

A sample problem of Newton's second law:

A lady pulling a cart with the mass of 35.6 and a force of 707N. What is the acceleration of the cart?
