Equations Flashcards
1
Q
Waves
Wave speed =
A
=frequency X wavelength
2
Q
Forces
Weight =
A
=mass X gravitational field strength
3
Q
Forces
Work done =
A
= force X distance ( moved along the line of the action of the force)
4
Q
Force
Force =
A
= Spring constant X extension
5
Q
Forces
Moment of a force =
A
= force X distance ( perpendicular to the direction of the force )
6
Q
Force
Pressure =
A
= force normal to a surface / area of that surface
7
Q
Forces
Distance travelled =
A
= speed X time
8
Q
Forces
Acceleration =
A
= change in velocity \ time taken
= final velocity - initial velocity / time taken
9
Q
Forces
Resultant force =
A
Mass X acceleration
10
Q
Forces
Momentum =
A
= mass X velocity
