6. a slow-motion, love potion, jumping off things in the ocean [INCOMPLETE]

Question 1

Momentum

Answer 1

a vector quantity that is the product of the mass and velocity of an object

Question 2

momentum, p (kgm/s) =

Answer 2

mass(kg)*velocity(m/s)

Question 3

impulse

Answer 3

the increase/decrease in momentum

Question 4

change in momentum =

Answer 4

Force * time

Question 5

area under a force time curve

Answer 5

the total impulse acting and the total change in momentum produced.

Question 6

principal of conservation of momentum

Answer 6

in a closed system, the total momentum is constant so the momentum before a collision is equal to the momentum afterwards.

Question 7

recoil

Answer 7

the movement backwards due to conserved momentum

Question 8

statics

Answer 8

objects in equilibrium

Question 9

dynamics

Answer 9

objects that are accelerating/decelerating

Question 10

Why is calculated momentum not always correct?

Answer 10

At high speeds mass increases and the equations are only valid for non relativistic speeds.

Question 11

elastic collision

Answer 11

100% of energy and momentum conserved

Question 12

impulse

Answer 12

change in momentum

Question 13

linking k.e. and momentum

K.E. =

Answer 13

p^2 / 2m
