Linear momentum Flashcards
1
Q
Define linear momemtum as:
Is it of scalar or vector nature?
A
- ๐ฉ = ๐๐ฏ
- It is a vector
2
Q
Recall and apply Newtonโs second law in the form:
A
- ฮฃ๐ = d๐ฉ/dt
3
Q
State the principle of conservation of momentum
A
- The total momentum before a collision = the total momentum after a collision, provided no resultant external force has acted
- It is always conserved
4
Q
Appreciate the principle as a consequence of Newtonโs second and third laws
A
