Chapter 2 - Mechanics (2.3) Flashcards
1
Q
What is momentum?
A
A measure of an object’s motion.
2
Q
What is the momentum equation?
A
Momentum (kgms) = mass x velocity
3
Q
Force equation using momentum?
A
Force = p/t
4
Q
Conservation of linear motion
A
When objects collide the total momentum of each object before collision is the same as the sum after collision
5
Q
Definition of an explosion?
A
Where a stationary object separates into component parts which move at different velocities. Momentum must be conserved in explosions
6
Q
Alternative equation for velocity combining GPE=Ke
A
V^2=2gh
