Kinematics

Question 1

Displacement, s

Answer 1

change in position of the object. It is the length and direction of the straight line drawn form the starting position to the final position of the object

Question 2

speed, v

Answer 2

rate of change of distance travelled with respect to time

Question 3

velocity, v

Answer 3

rate of change of displacement with respect to time

Question 4

Acceleration, a

Answer 4

rate of change of velocity with respect to time

Question 5

Derivation of equations of motion

Answer 5

a= Δvelocity/time taken
= (v-u)/t

v = u + at

s = area under v-t graph
= ut + 1/2 (v- u) t
= ut + 1/2 a t²

sub t = ( v - u)/t in s = 1/2 (u + v)t

v² = u² + 2as
