Electricity and Energy National 5 Physics Summary Notes
... As discussed above, the temperature of an object is a measure of the mean kinetic energy of its particles. The most common everyday temperature scale is the Celsius scale (often referred to as the centigrade scale). This scale is based on the freezing (0 oC) and boiling point of water (100 oC). Howe ...

... Work depends on both force and distance: Wprof on cart = Fprof on cart∆x. Along path 1, the professor pushes the cart for less distance (as noted in part A), but he exerts a greater force, since he’s fighting gravity head-on (as noted in part B). By contrast, along path 2, the professor pushes with ...

3) Can friction ever do positive work?
... book on a table has positive PE if the zero reference level is chosen to be the floor. However, if the ceiling is the zero level, then the book has negative PE on the table. It is only differences (or changes) in PE that have any physical meaning. ...

Summary of Newton`s Laws
... When you sit in your chair, your body exerts a downward force on the chair and the chair exerts an upward force on your body. There are two forces resulting from this interaction - a force on the chair and a force on your body. These two forces are called action and reaction forces and are the subje ...

PLANAR KINETICS OF A RIGID BODY WORK AND ENERGY
... Here ( W ork1→2 )noncons represents the work of the non-conservative forces such as friction. If this term is zero then KE1 + U1 = KE2 + U2 This equation id refereed to as the conservation of mechanical energy. It states that the sum of the potential and kinetic energies of the body remains constant ...

ultraviolet light which of the following best illustrates the physics
... A. Energy is a quantity that can be created or destroyed. B. Energy is a measure of how much money it takes to produce a product. C. The energy of an object can never change. It depends on the size and weight of an object. Energy causes matter to change and determines how much change occurs. ...

The Nature of Force and Motion
... 26. Newton’s 3rd Law of Motion – If one object exerts a force on another object, then the 2nd object exerts a force of equal strength in the opposite direction on the 1st object. 27. Newton’s 3rd Law of Motion - For every action force there is an equal in strength and opposite in direction reaction ...
