3 cards from this section. Quick, good the night before a test.
What is the formula for momentum?
Think about what momentum combines.
What units are used to measure momentum?
How do you measure mass and velocity?
What does momentum depend on?
Look at the formula p = mv.
True or false: The law of conservation of momentum states that momentum can be created in an isolated system.
Recall the definition of conservation.
A 2 kg cart moving at 3 m/s collides with a stationary 4 kg cart. Assuming a perfectly elastic collision, calculate the final velocities of both carts.
Apply conservation of momentum and elastic collision formulas.
If a 5 kg object moving at 10 m/s collides with a 3 kg object at rest and they stick together, find their shared velocity after the collision.
Use p_initial = p_final and consider both objects as a single unit post-collision.
