Scientific Equations Flashcards
Write down the equation that links Weight, mass and Gravitational
field strength?
Weight = mass x gravitational field strength (g)
Write down the equation that links
work done, force and distance
(along the line of action of the
force)
Work done = force x distance (along the line of action of the force)
Write down the equation that links
Force applied to a spring, the
spring constant and the extension?
Force applied to a spring = spring constant x extension
Write down the equation that links distance travelled, speed and time?
Distance travelled = speed x time
Write down the equation that links
Acceleration, change in velocity and time taken?
Acceleration = change in velocity / time taken
Write down the equation that links resultant force, mass and acceleration?
Resultant force = mass x acceleration
Write down the equation that links
momentum, mass and velocity?
Momentum = mass x velocity
Write down the equation for kinetic energy?
Kinetic energy = 0.5 x mass x (mass)2
Write down the equation that links
Gravitational potential energy, gravitational field strength, mass and height?
Gravitational potential energy = mass x gravitational field strength (g) x height
Write down the equation that links power, energy transferred and
time?
Power = energy transferred / time
Write down the equation that links
power, work done and time?
Power = work done / time
Write down the equation that links energy transferred, power and time?
Energy transferred = power x time
Write down the equation for efficiency?
There are two!
Efficiency = useful output energy transfer / total input energy transfer
Efficiency = useful power output / total power input
Write down the equation that links
wave speed, frequency and wavelength?
Wave speed = frequency x wavelength
What is the equation for density
when you are given the mass and
volume?
Density = mass / volume
