Formulas Flashcards
How do you calculate acceleration using Velocity?
By subtracting the Initial Velocity from the Final Velocity and dividing that by seconds taken. Example
How do you calculate Speed with distance and time?
By dividing distance by time. Example
How do you calculate Distance with speed and time?
By multiplying speed and time. Example
How do you calculate Time with distance and speed?
By dividing distance by speed. Example
How do you calculate Potential energy?
Multiply the object’s Mass in kg by 10m/s/s [accel because of gravity] and times that by Height in meters. Example
How do you calculate Kinetic Energy?
Multiply the objects mass in kg by it’s velocity^2, then halve that. Example
How do you calculate Momentum?
By multiplying Mass in kg and Velocity. Example
What is the formula for the law of universal gravitation?
Where m1 m2 are the masses of the two objects. r is the distance between the objects. and G is the gravitational constant
How do you calculate Force with mass?
Multiply mass in kg by acceleration (m/s^2). Example
How do you calculate acceleration using force?
Divide Force in Newtons by mass in kg. Example
How do you calculate mass using force?
Divide force in Newtons by acceleration in m/s^2. Example.
How do you calculate the Gravitational Potential Energy of an object at rest?
Mass in kg x Acceleration due to gravity (9.8) x height in meters
What is ohms formula?
V=Voltage in volts, R=Resistance in ohms, I=Current in Amperes
How do you calculate Potential difference (Voltage) with a quantity of charge and the work done?
If W is work done in Joules
& Q is quantity of charge in Coulombs
What is Einstein’s most popular formula?
E: Energy in Joules, m: mass in kg, c: speed of light (3x10^8 m/s)
How to calculate work done with force and distance?
