Equations Flashcards
1
Q
Weight
A
Weight = Mass x gravity
2
Q
Work done
A
Work done = Force x distance
3
Q
Extension
A
Force = spring constants x extension
4
Q
Acceleration linking velocity and time
A
Acceleration = change in velocity/time
5
Q
Acceleration linking force and mass
A
Acceleration = mass x acceleration
6
Q
Stopping distance
A
Stopping distance = thinking distance + breaking distance
7
Q
Momentum
A
Momentum = mass x velocity
8
Q
Frequency
A
Period = 1/frequency
9
Q
Wave speed
A
Wave speed = frequency x wavelength
10
Q
Size of force (motor effect)
A
Size of force = magnetic flux density x current x length
