General Physics Flashcards
1
Q
Speed
A
Total distance / total time
2
Q
Acceleration
A
Change in speed/time taken
3
Q
Weight
A
Mass x gravitational field strength (9.8)
4
Q
Force
A
Mass x acceleration
5
Q
Momentum
A
Mass x velocity
6
Q
Impulse
A
F x t
Impulse also equals final momentum - initial (change in momentum)
7
Q
Force
A
Spring constant x extension
(Hooke’s law)
8
Q
Moment
A
Force x perpendicular distance to the pivot
9
Q
Density
A
Mass / volume
10
Q
Resultant force
A
Gives an acceleration to the object
11
Q
Scalar
A
Distance, speed, time
12
Q
Vectors
A
Velocity, acceleration
13
Q
Pressure
A
Force (N)/area(m2)
14
Q
Change in pressure
A
Density of a liquid x gravitational x change in height
15
Q
Kinetic energy
A
Movement
