momentum

Question 1

the equation and units for momentum

Answer 1

p = mv
units = kgm/s

Question 2

time taken for the change in momentum to occur is proportional to the …. ???

Answer 2

resultant force

Question 3

Give the equation linking resultant force and momentum

Answer 3

change in momentum (kgm/s) = resultant force (N) x time (s)

mv-mu = Ft
(where m = mass, v = initial velocity, u = final velocity, F = force, t = time)

Question 4

what is impulse ?

Answer 4

the change in momentum of an object caused by a force acting on it for a length time

Question 5

how do u calculate impulse?

Answer 5

Change in momentum
= applied force x elapsed time

\Delta p (Change in momentum) =
F (applied force) X
\Delta t (elapsed time
)
