EQUATIONS Flashcards
1
Q
average speed =
A
average speed = distance / time
2
Q
force =
A
force = mass x acceleration
3
Q
acceleration =
A
acceleration = change in velocity / time
4
Q
momentum =
A
momentum = mass x velocity
5
Q
density =
A
density = mass / volume
6
Q
work done =
A
work done = force x distance moved
7
Q
energy transferred =
A
energy transferred = work done
8
Q
kinetic energy =
A
1/2 x mass x speed²
9
Q
gravitational potential energy =
A
gravitational potential energy = mass x gravity x height
10
Q
weight =
A
weight = mass x gravitational field strength
11
Q
pressure =
A
pressure = force / area
12
Q
moment =
A
moment = force × perpendicular distance from the pivot
13
Q
charge =
A
charge = current × time
14
Q
voltage =
A
voltage = current × resistance
15
Q
electrical power =
A
electrical power = voltage × current
