What is one assumption made in projectile motion models?.
- A.Air resistance is negligible.
- B.The projectile is launched at an angle of 90 degrees.
- C.The mass of the projectile affects its trajectory.
- D.The initial velocity is always constant.
Model answer
What a good answer should say
- Air resistance is negligible.
Explanation
Why this works
In projectile motion models, it is assumed that air resistance is negligible, allowing for simplified calculations of the projectile's path. This assumption helps in analyzing the motion without the complexities introduced by drag forces.
