Physical Science: Chapter 13 Section 3: Energy _____________ The ability to do __________ Whenever ________is done, _________MUST a). Be ______________between objects OR b). _____________into another form of energy.

ENERGY The amount of _______used can be found by calculating the amount of ____________done. Work =________________ Because energy is the ability to do Work, _____ and _______are measured in the _____units, ______.

Physical Science: Chapter 13 Section 3: Energy There are two broad categories of energy: 1. ________________energy 2. ________________energy

_______________energy is the __________energy of a system. POTENTIAL ENERGY _______________energy is the __________energy of a system. It is also called the energy of __________, because it can result from the _________________ ___________________________.

________________potential energy ____________potential energy There are multiple kinds of potential energy: ________________potential energy ____________potential energy ______________potential energy

Physical Science: Chapter 13 Section 3: Energy POTENTIAL ENERGY ____________________________ is created by positioning an object above the surface of the Earth.

G.P.E. = ___x ___x ___ Units: kg * m/s2 * m = kg*m2/s2 = __________ GRAVITATIONAL POTENTIAL ENERGY ● Depends on: the mass of the object, the acceleration due to gravity and the height above the surface of the Earth. G.P.E. = ___x ___x ___ Units: kg * m/s2 * m = kg*m2/s2 = __________ Since the (m x g) = ____________, G.P.E. = ___ x ____

Physical Science: Chapter 13 Section 3: Energy _____________POTENTIAL ENERGY ● Depends on the __________of the elastic band, spring or other bent object the __________that the band, spring or object is bent.

Physical Science: Chapter 13 Section 3: Energy _______________ POTENTIAL ENERGY ● Is a type of potential energy stored in the ______________ __________________. ________________is released by changes in the structure of atoms’ nuclei.

Physical Science: Chapter 13 Section 3: Energy _____________POTENTIAL ENERGY ● Is a type of potential energy stored in _______

Physical Science: Chapter 13 Section 3: Energy KINETIC ENERGY ___________ energy is the energy possessed by __________objects.

Kinetic Energy Kinetic Energy is dependent on the mass and the velocity of the object. The formula is: KE = Notice that the Kinetic Energy (KE) is affected by both mass and velocity (speed). However, the ____________________makes a greater difference because it is squared in the equation. Units are kg*m2/s2 which is equal to a ______.
