Physics Equations

Basic Science Bowl Middle School Equations to Know

ItemEquation
Velocity (2 Equations) Final Velocity = Root of [Initial Velocity Squared + 2*Acceleration(final position-initial position)] Final Velocity = Initial Velocity + Acceleration (Time)
Final Position Final Position = Initial Position + Initial Velocity*Time+1/2*Acceleration*Time Squared
Force Coefficient of Friction Normal Force Frictional Force Force = Mass * Acceleration Coefficient of Friction = Force Required/(Mass * Acceleration Due To Gravity) Normal Force = Mass * Acceleration Due to Gravity cos(θ) Frictional Force = Coefficient of Friction * Normal Force
Weight Weight = Mass * Acceleration Due To Gravity
Centripetal Acceleration Centripetal Acceleration = Velocity of Object Moving along a circular path * Radius of the circular path
Gravitational Force Gravitational Force = Universal Gravitational Constant (6.674* 10 to the -11 Newton meter squared per kilogram squared) * (Mass of Object One * Mass of object Two)/Distance Squared
Acceleration Due To Gravity Acceleration Due To Gravity = Universal Gravitational Constant (6.674* 10 to the -11 Newton meter squared per kilogram squared)* Mass of the Object Creating the Gravitational Field/Distance Between the Two Objects Squared
Centripetal Acceleration Centripetal Acceleration = Velocity of Object Moving along a circular path squared / Radius of the circular path
Gravitational Force Gravitational Force = Universal Gravitational Constant (6.674* 10 to the -11 Newton meter squared per kilogram squared) * (Mass of Object One * Mass of object Two)/Distance Squared
Acceleration Due To Gravity Acceleration Due To Gravity = Universal Gravitational Constant (6.674* 10 to the -11 Newton meter squared per kilogram squared)* Mass of the Object Creating the Gravitational Field/Distance Between the Two Objects Squared
Frequency Frequency=1/Time Period
Relationship Between: Velocity/Wavelength/Frequency/Period Velocity=Wavelength/Period=Wavelength*Frequency
Force Applied To the Spring Force Applied = Spring Constant(Stiffness) * Displacement From Equilibrium
Electrical Resistance Electrical Resistance = resistivity (in ohm-meters)*Length Of the Conductor/Cross Section Area
Capacitance(Farads) Capacitance = Electric Charge in Capacitor(Columbus)/Voltage Across Capacitor
Linear velocity of a point on a rotating object Linear Velocity of Point On Rotating Object = Angular Velocity(Radians) * Radius From Axis of Rotation
Fraction Submerged Fraction Submerged = Volume Of Submerged Object/Total Volume of the Object
Density Specific Gravity Density = Mass/Volume Specific Gravity = Density of Substance/Density of Water at 4 degrees Celsius (1000kg/meter cubed)
Two Pressure Formulas Pressure = Force/Area Pressure = Density*Acceleration Due to Gravity*Height of the Fluid Column
Two Equations for Work(Joules) Work=Force*Distance*cosθ-if Degree is 90, no work done, if 0 max work done Work = 1/2*Mass*Final Velocity Squared-1/2*Mass*Initial Velocity Squared
Kinetic Energy (Joules) Kinetic Energy = 1/2 mass*velocity squared
Gravitational Potential Energy Gravitational Potential Energy = Mass * Acceleration Due to Gravity * Height
Efficiency Efficiency = Work Output/Work Input
Power(Watts) Power = Work/Time
Linear Momentum Change In Momentum Linear Momentum = Mass*Velocity Change In Momentum = Net force applied to the Object/Change In Time
Law of Conservation Of Energy Mass of Object One*Initial Velocity of Object One + Mass of Object Two*Initial Velocity of Object Two = Mass of Object Two*Final Velocity of Object One + Mass of Object Two*Final Velocity of Object Two
Torque (Newton Meters) Torque = Force· Distance· sin(theta)
Resistance Between Two Points (Ohms) Resistance Between Two Points (Ohms) = Volts/Amps
Amount Of Electrical Charge in Motion Per Unit Time (Amps) Amount Of Electrical Charge in Motion Per Unit Time (Amps) = Watts/Volts
Electrical Potential Difference (Volts) Electrical Potential Difference (Volts) = Amps*Ohms
Electric Charge (Columb) Electric Charge (Columb) = Ampere Per Second
Free Fall-Time Free Fall-Time = Root Of [(2· Height)/9.8]
Wavelength Velocity/Frequency
Molarity-Concentration(Moles Per Liter) Molarity=Moles of Solute(Dissolved Substance)/Liters Of Solution

Use these flashcards to help memorize information. Look at the large card and try to recall what is on the other side. Then click the card to flip it. If you knew the answer, click the green Know box. Otherwise, click the red Don't know box.

When you've placed seven or more cards in the Don't know box, click "retry" to try those cards again.

If you've accidentally put the card in the wrong box, just click on the card to take it out of the box.

You can also use your keyboard to move the cards as follows:

If you are logged in to your account, this website will remember which cards you know and don't know so that they are in the same box the next time you log in.

When you need a break, try one of the other activities listed below the flashcards like Matching, Snowman, or Hungry Bug. Although it may feel like you're playing a game, your brain is still making more connections with the information to help you out.

To see how well you know the information, try the Quiz or Test activity.
