SUMMARY

In a collision between a truck and a car, the change in velocity will not be the same due to their differing masses. According to the principle of conservation of momentum, the total momentum before the collision equals the total momentum after the collision. However, the change in momentum, calculated as p=mv, will be equal for both vehicles, but the resulting change in velocity will differ based on their respective masses.

PREREQUISITES
  • Understanding of basic physics principles, particularly momentum and mass.
  • Familiarity with the equation for momentum, p=mv.
  • Knowledge of collision types (elastic vs. inelastic).
  • Basic grasp of velocity and its relationship to mass in collision scenarios.
NEXT STEPS
  • Study the conservation of momentum in different types of collisions.
  • Learn about elastic and inelastic collisions and their implications on velocity changes.
  • Explore real-world applications of momentum in vehicle safety design.
  • Investigate how mass affects the outcome of collisions in various scenarios.
USEFUL FOR

Physics students, automotive engineers, and anyone interested in understanding the dynamics of vehicle collisions and momentum principles.

If a truck and a car collide will they both have the same change in velocity?

Since the momentum before has to equal the momentum afterward wouldn't the change in the velocity also be equal?

Thank you.

No, because they have different masses. Their change in momentum will be equal, p=mv.
