momentum - Sp2

Question 1

what is the definition of momentum?

Answer 1

a measure of tendency of an object to keep moving

Question 2

What is momentum dependant on?

Answer 2

mass and velocity

Question 3

what equation is used to find momentum as a force?

Answer 3

change in momentum/ time

or

mv-mu/t

Question 3

what’s the equation for momentum?

Answer 3

mass (kg) x velocity (m/s)

or

p = m x v

Question 4

What is true about the total momentum of objects before and after a collision when no external forces are acting upon them?

Answer 4

they are the same

Question 5

what is conservation of momentum?

Answer 5

when the total momentum of 2 moving objects before and after a collision is the same (without any external forces)

Question 6

is momentum vector or scalar?

Answer 6

vector - always consider direction

Question 7

if 2 objects are moving in opposite directions, what signs are placed in front to indicate direction?

Answer 7

one would be a negative sign, the other positive
