Atomic mass mass of an atom in atomic mass units An atomic mass unit is equal to? One twelth the mass of one carbon-12 atom The average atomic mass is equal to? atomic mass on the periodic table Isotopes are atoms of the same element with a different number of ___ and so they have different ___ 1) neutron 2) masses Mole Is a counter and relates to mass.* It is similar to a dozen. *It can count the number atoms/molecules/particles. Molar Mass *is the mass of one mole of the substance. *g/mol = atomic mass of the element *molar mass of an element contains mols of atoms Avogadro's number particles/atoms/molecueles > moles *6.022x10^23 Percent Composition Mass of element/ mass of compound x 100 Tell how much an element contributes to the mass of the compound

APPHY6.T7practicetest Try the following practice test questions. Then, compare your work to the key on the last page 1. Which of the following quantities are units of momentum? (There could be more than one correct choice.) A) N ? m B) kg ? s/m C) kg ? m/s D) N ? s E) kg ? m2/s2 2. The momentum of an isolated system is conserved A) only in inelastic collisions. B) only in elastic collisions. C) in both elastic and inelastic collisions. 3. During World War I, Germany used a "Big Bertha" cannon to hurl shells into Paris 30 miles away. This gun also had a very long barrel. What was the reason for using a long barrel in these guns? A) to exert a larger force on the shells B) to reduce frictional losses

Newton?s 3 Laws Of Motion Mia Bentley and Dekendrick Bullie 2nd period 10/9/15 Newton?s 1st law An object at rest will remain at rest unless effected by an unbalanced force. An object in motion stays in motion at the same speed unless effected by an unbalanced force. Also known as law of inertia There is a natural tendency for objects to do their own thang All objects resist changes in their states of motion and will maintain motion if not affected by an unbalanced force Any object in motion involves acceleration and then applies the second law Everyone continues in a state of rest or moving uniformly except being when its changed by an outside force Force is necessary for the change of velocity (no force, no acceleration) Newton?s 1st law .

Atomic Structure The discovery of atoms began with Democritus, a Greek philosopher, who was the first person to suggest that atoms exist. However Democritus made the false claim that atoms were indestructible which was proven wrong with the development of the atomic bomb (nuclear power), additionally he did not support his idea with scientific evidence or explain the chemical behavior of the atom. Following Democritus was Dalton who took the idea of the atom and explained it and supported it with scientific methods. Atom= The smallest particle of an element that retains its identity within chemical reactions due to maintaining chemical and physical properties. Dalton?s Atomic Theory: All elements are composed of indivisible particles called atoms (later disproved)

Adelinne Wenger Analyzing Newton?s Second Law of Motion Lab #10 12/2/15 Mr. Glasel Period 5 Purpose: To show how the acceleration of an object depends on the applied force if the mass unchanged. The second to show the relationship between mass and acceleration for a constantly applied force and varying total mass. Introduction

AP Physics Multiple Choice Practice ? Torque 1. A uniform meterstick of mass 0.20 kg is pivoted at the 40 cm mark. Where should one hang a mass of 0.50 kg to balance the stick? ?(A) 16 cm (B) 36 cm (C) 44 cm (D) 46 cm (E) 54 cm 2. A uniform meterstick is balanced at its midpoint with several forces applied as shown below. If the stick is in equilibrium, the magnitude of the force X in newtons (N) is?(A) 50 N (B) 100 N (C) 200 N (D) 300 N (E) impossible to determine without the weight of the stick 3. A door (seen from above in the figures below) has hinges on the left hand side. Which force produces the largest torque? The magnitudes of all forces are equal.
