Question 1.
Define momentum.
Show hintHide hint
Think about how speed and mass interact.
Question 2.
What happens to momentum during a collision?
Show hintHide hint
Consider the total mass and velocities before and after the collision.
3Question 3.
In an elastic collision, what is conserved?
- Momentum
- Kinetic Energy
- Both
Show hintHide hint
Remember what happens during a bouncing interaction.
4Question 4.
True or False: Inelastic collisions conserve kinetic energy.
- True
- False
Show hintHide hint
Consider a scenario where objects stick together after collision.
Question 5.
Mass m1 (3 kg) traveling 5 m/s collides with stationary mass m2 (5 kg). If the collision is perfectly elastic, find the final velocities of both masses.
Show hintHide hint
Set up the equations from both conservation principles.
Question 6.
In a two-dimensional collision, mass m1 (2 kg) moving at 4 m/s collides elastically with mass m2 (2 kg) at rest at an angle of 30 degrees. Calculate the velocities after the collision.
