Exploring the Five Basic Laws of Energy and Change
Discover the fundamental principles of energy and change through the five basic laws explained in this insightful presentation. From unbalanced forces to energy conservation, each law sheds light on the dynamics of motion, balance, transfers, and transformations in the realm of energy. Dive into the world of physics and understand how these laws govern various phenomena, leading to a comprehensive understanding of the interconnectedness of energy and change.

Ed Energy explains the five basic rules of Energy and Change
Energy and Change: the basic five laws Law # 1. Law # 1. An unbalanced force acting on a body results in a change in motion . What this means: What this means: the balancing scales will not move until we do what??? Apply a weight (an unbalanced force!)
Energy and Change: the basic five laws Law # 2: Law # 2: Objects remain stationary or in constant motion under the influence of balanced forces What this means: What this means:The wheel will continue to spin and spin and spin until what??? We unbalance it (here, with brakes). Note that, once it stops, the wheel is once again in balance.
Energy and Change: the basic five laws Law # 3: Law # 3: Energy can be transferred from one medium to another. What this means: What this means: When we heat the pot what happens? The energy from the fire is transferred to the water!
Energy and Change: the basic five laws Law # 4: Law # 4: Transfers of energy can vary according to the medium in which it travels. What this means: What this means: When you put a pencil into a glass of water what happens? Thanks to the refracting property of water, the pencil appears to be bent!
Energy and Change: the basic five laws Law # 5: Law # 5: Energy is conserved when it is transferred or transformed What this means: What this means: When you turn on a bulb, you get energy in the form of light, but you get what other form of energy as well? Stumped? Then, do the experiment with your teacher!
