Kinematics Flashcards
0
Q
scalar
A
a physical quantity that only has a magnitude
1
Q
vector
A
a physical quantity which has both a magnitude and a direction
2
Q
distance
A
the length of the path travelled
3
Q
displacement
A
the change in position of a body (∆x)
4
Q
speed
A
the rate of change of distance
5
Q
velocity
A
the rate of change of displacement
6
Q
when there is no displacement?
A
velocity = 0
7
Q
acceleration
A
rate of change of velocity
8
Q
rule 1 (x)vs(t)
A
gradient is equal to velocity
9
Q
rule 2 (v) vs (t)
A
the gradient of the graph = acceleration
10
Q
rule 3 (v) vs (t)
A
the area under the graph = ∆x displacement
11
Q
Free fall
A
The only force acting on it is the gravitational force
12
Q
Terminal velocity
A
Magnitude of gravitational force =magnitude of frictional force
