2. • How do we apply conservation of momentum to
two dimensions?
Conservation of
Momentum
3. • Conservation of energy and momentum can be analyzed
in two or three dimensions
• Math can quickly become complex
• We will start with one object in motion and the second at
rest
Two-Dimensions
4. • Billiard ball A moving with
speed vA = 3.0 m/s in the +x
direction strikes an equal
mass ball B initially at rest
• After the collision, ball A
moves 45° above the x axis
• Ball B moves 45° below the
x axis
• What are their final speeds?
