Physics Equations Flashcards
What is the equation for weight?
weight = mass x gravitational field strength
What is the equation for the force applied to a spring?
force applied to a spring = spring constant x extension
What is the equation for acceleration?
acceleration = change in velocity / time taken
What is the equation for density?
density = mass/volume
What is the equation for work done?
work done = force x distance along the line of action of the force)
What is the equation for distance traveled?
distance travelled = speed x time
What is the equation for resultant force?
resultant force = mass x acceleration
What is the equation for efficiency?
Efficiency = useful output energy transfer/total input energy transfer
What is the equation for wave speed?
Wave speed = frequence x wavelength
What is the symbol for displacement or distance?
s
What is the symbol for initial velocity?
u
