forces equations Flashcards
1
Q
weight
A
mass × gravitational field strength
2
Q
work done
A
work done = force × distance
(moved along the line of action of the force)
3
Q
force
A
spring constant x extension
4
Q
moment of a force
A
force distance
(perpendicular to the direction of the force)
5
Q
pressure
A
=
force normal to a surface /
area of that surface
6
Q
distance
A
speed xtime
7
Q
acceleration
A
change in velocity/ time taken = final velocity-initial velocity/ time taken
8
Q
resultant force
A
mass x acceleration
9
Q
momentum
A
mass x velocity
