kinematics Flashcards
1
Q
what are scalar quantities?
A
quantities that only have magnitude
2
Q
what are vector quantities?
A
quantities that have magnitude and direction
3
Q
what is speed?
A
distance moved per unit time
4
Q
what is velocity?
A
rate of change of displacement
5
Q
what is acceleration?
A
the rate of change of velocity
6
Q
what is uniform acceleration?
A
it is the constant rate of change of velocity
7
Q
what is terminal velocity?
A
objects experience a higher air resistance when their speed increases. when air resistance against an object is equal to its weight, the object starts to travel at a constant speed.
