Flashcards in Equations complete Deck (15):
What is the equation that links weight, mass and gravity?
weight = mass × gravitational field strength (g)
W=M x G
What equation links work done, force and distance.
work done = force × distance
along the line of action of the force
What equation links force spring constant and extension
force applied to a spring = spring constant × extension
What equation links distance, speed and time?
distance travelled = speed × time
S= D x T
What equation links acceleration velocity and time.
change in velocity
What links resultant force with mass and acceleration
resultant force = mass × acceleration
What equation links momentum, mass and velocity.
momentum = mass × velocity
What links kinetic energy, 0.5 mass and speed.
kinetic energy = 0.5 × mass × speed
