UNBALANCED FORCES
... The Atwood’s Machine Lab was an excellent example for illustrating the differences in balanced versus unbalanced forces. The lab exercise mostly focused on the application of Newton’s second law. On step one the forces were balance on both sides of the machine because there was equal mass on each si ...

... So, objects in motion are said to have momentum. This momentum is a vector. It has a size and a direction. The size of the momentum is equal to the mass of the object multiplied by the size of the object's velocity. The direction of the momentum is the same as the direction of the object's velocity. ...

3rd Law: Force every action force there is an equal and opposite
... The greater the mass or acceleration an object has, the greater the force of that object. Also, a larger force must be exerted on an object with greater mass in order for it to have the same acceleration as an object with less mass. What is a force? A force is a push or pull that can change the moti ...
