Exam-style question
Try this first
Which of the following is NOT an assumption made in ideal projectile motion?.
- A.The only force acting on the projectile is gravity.
- B.The projectile travels in a straight line.
- C.The launch angle affects the range.
- D.The motion occurs in a vacuum.
Model answer
What a good answer should say
- The projectile travels in a straight line.
Explanation
Why this works
In ideal projectile motion, the path of the projectile is a curved trajectory due to the influence of gravity, not a straight line. This is a key distinction in understanding projectile motion.
