Topic 5 - Forces Flashcards
1
Q
Weight
A
Weight = Mass × Gravitational Field Strength
W = mg
2
Q
Work Done
A
Work done = Force x Distance
3
Q
Force
A
Force = Spring Constant x Extension
Force = change in momentum ÷ time taken
4
Q
Moment of a force
A
Moment of a Force = force x distance (perpendicular to the direction of the force)
5
Q
Pressure
A
pressure =
force normal to a surface ÷
area of that surface
6
Q
Distance Travelled
A
Distance Travelled = Speed x Time
7
Q
Acceleration
A
1) Acceleration = change in velocity ÷ time taken
2) Acceleration =
(final velocity - initial velocity) ÷
time taken
8
Q
Resultant Force
A
Resultant Force = Mass x Acceleration
9
Q
Momentum
A
Momentum = Mass x Velocity
