chapter 2 - kinematics Flashcards
1
Q
speed
A
distance travelled per unit time
2
Q
velocity
A
rate of change of displacement
3
Q
uniform speed
A
distance travelled per unit time remains constant throughout
4
Q
acceleration
A
rate of change of velocity
5
Q
acceleration due to gravity
A
for free-falling objects, it will always accelerate uniformly at 10m/s2 towards centre of earth as it only takes place under influence of gravity (with ignorance of air resistance)
