Interactive Quizzes
Engage in quick quizzes to reinforce what you've learned and check your comprehension.
Question 1
True or False: Momentum is conserved only in elastic collisions.
💡 Hint: Consider inelastic and perfectly inelastic collisions as well.
Question 2
What is the x-component of momentum if a 4 kg object moves at 3 m/s at an angle of 60 degrees?
- 2 kg*m/s
- 3 kg*m/s
- 6 kg*m/s
💡 Hint: Remember how to calculate the horizontal component with cosine.

Challenge Problems
Push your limits with challenges.
Question 1
A 10 kg cart moves at 5 m/s colliding with a 5 kg cart moving at 3 m/s in the opposite direction. Calculate the velocity of both carts post-collision assuming they stick together.
💡 Hint: Remember to account for the opposite direction as negative momentum.
Question 2
Two ice skaters push away from each other: Skater A with 60 kg moves with a speed of 1.5 m/s while Skater B weighs 40 kg. What will be the speed of Skater B after the push?
💡 Hint: Remember that the signs indicate directions.
