kinematics Flashcards
1
Q
scalar quantities
A
physical quantities that have magnitude only
2
Q
vector quantities
A
physical quantities that have both magnitude and direction
3
Q
speed
A
distance moved per unit time
distance travelled/time taken
4
Q
velocity
A
rate of change of displacement
displacement/time taken
5
Q
acceleration
A
rate of change of velocity
change in velocity/time taken
6
Q
uniform acc
A
constant rate of change of velocity
7
Q
displacement time graph
A
gradient=velocity
8
Q
velocity time graph
A
gradient=acceleration
area under graph=displacement
9
Q
terminal velocity
A
weight equals to air resistance against it
10
Q
air resistance
A
velocity or speed x surface area
