Momentum

mass or intertia in motion

2
New cards

Formula for momentum

p = mv

3
New cards

Change in momentum formula

Δp = mΔv (pf - pi = m x (vf - vi))

4
New cards

To change momentum, you need to change ___ or ___

Mass or velocity

5
New cards

To change velocity you need _____ forces

unbalanced

6
New cards

Impulse momentum theorem

FΔt = Δp

7
New cards

Conservation of Momentum

occurs in all interactions, total momentum before = total momentum after interaction

8
New cards

Conservation of Ek

occurs in only elastic collisions, total Ek before = total Ek after interaction
