... about work and energy; this week, we’re doing more about energy. Specifically, we are learning about one of the most important concepts in all of physics: the law of conservation of energy. This law states that energy cannot be created or destroyed, it can only be converted from one form into anothe ...

Newton`s Second Law
... Newton’s First Law: An object at rest remains at rest, and an object in motion remains in motion with the same speed and direction (maintains its velocity) unless it experiences an unbalanced force. Example: A soccer ball resting on the grass remains motionless until a force is applied (a kick). Th ...

This will be done by directly measuring the initial height of a mass above a reference level and then measuring the velocity of the mass at that level. This will allow us to calculate the mechanical energy of the system at each point and to check if ...
