B2B

• Weight/Force = mass x acceleration
• Inertia - an object at rest will remain at rest unless acted upon by an external force
• Acceleration - the net force is directly proportional to its acceleration and inversely proportional to its mass
• Interaction - For every action there is an equal and opposite reaction
• Friction - the resistance to motion between two materials in contact
• Static, Kinetic, Rolling, Fluid - Types of friction
• Uniform Circular Motion - motion in a circle at a constant speed and always acts perpendicular to the direction of motion
• Work - the force is parallel to the displacement
• James Prescot Joule - Scientist for the based for the unit of work
• Fdcostetha - Work Formula
• Energy - the ability to do work
• Potential Energy - stored energy
• Kinetic Energy - Energy in Motion
• Mechanical - sum of potential and kinetic energy
• Gravitational PE =mgh
• Elastic Potential Energy = (1/2)kx^2
• Kinetic Energy = 1/2mv2
• Power - inversely proportional to time, directly proportional to force and displacement
• Wave - Transfer of Energy
• Solid - sound travels fastest in
• 2-atoms - diatomic
• 1-atom - monoatomic
• True - True/False When temperature increases so does velocity
• White Light is the combination of many colors
• False - True/False Electro magnetic spectrum is measured in kilometers
• Three types of Heat - Convection, Radiation, Conduction
• Electrical Circuit = a closed conducting path where charges flow
• Current = A-> I=q/t
• Electrical Current - Amount of charge passing through any point per unit time
• Resistance - opposition a material offers to the flow of charges
• R = ohm( omega )
• Voltage = amount of energy needed to move a charge from 1 point to another
• Earthquake - sudden shaking of Earth's surface
• Fault - A fracture in the earth's crust that causes a displacement of the surface
• Focus - origin of the earthquake
• Fault Plane - the line/crack underground
• Fault Line - how much movement has taken place
• Epicenter - the direct location is above the focuis
• Intensity - How much a certain place was shaken up
• Magnitude - energy released from the focus
