Physics - Collisions in 2D
What is the formula for the vertical component of a momentum $p$?
What is the formula for the horizontal component of a momentum $p$?
If an object with mass $m _ 1$ is travelling in a straight line with velocity $v _ 1$, what is its momentum?
If an object with mass $m _ 1$ is travelling at an angle $\theta _ 1$ to the $x$ direction with velocity $v _ 2$, what is its momentum?
What is true about $\theta _ 1$ and $\theta _ 2$ for two identical masses in a 2D collision?
If two objects have the same mass, what angle do they make with each other in a 2D collision?
What is true about momentum in a 2D collision?
It is conserved in both the $x$ and $y$ directions.
How are collisions in 2D similar to projectiles?
You treat the horizontal and vertical components seperately.
What is the vertical component of momentum for an object moving only in the $x$ direction?
After a collision, one object has mass $m _ 1$ and velocity $v _ 2$ at an angle of $\theta _ 1$. The other object has a mass $m _ 2$ and velocity $v _ 3$. What is the horizontal component of momentum after the collision?
After a collision, one object has mass $m _ 1$ and velocity $v _ 2$ at an angle of $\theta _ 1$. The other object has a mass $m _ 2$ and velocity $v _ 3$. What is the vertical component of momentum after the collision?

\[m _ 1v _ 2\sin\theta _ 1 + m _ 2v _ 3\sin\theta _ 2 = 0\]How could you rewrite this??
\[m_1m_2\sin\theta_1 = -m_2v_3\sin\theta_2\]
