Projectile Motion starts at 9 and continues till grade 12. QuestionsToday has an evolving set of questions to continuously challenge students so that their knowledge grows in Projectile Motion. How you perform is determined by your score and the time you take. When you play a quiz, your answers are evaluated in concept instead of actual words and definitions used.
See sample questions for grade 12
A ball is thrown horizontally from a 20 m high tower. If it lands 40 m away from the base, what was its initial speed? (Take g = 10 m/s²)
A ball is thrown horizontally from the top of a 45 m high cliff with a speed of 10 m/s. How long does it take to reach the ground? (Take g = 9.8 m/s²)
A football is kicked at 15 m/s at an angle of 45° to the horizontal. What is its range? (Take g = 10 m/s², sin 90° = 1)
A projectile is launched at 20 m/s at an angle of 60° above the horizontal. What is the vertical component of its initial velocity? (Take sin 60° = 0.866)
A projectile is launched at 25 m/s at 37° above the horizontal. Calculate the time of flight. (Take g = 10 m/s², sin 37° = 0.6)
A projectile is launched at an angle θ with initial speed u. At what point(s) during its flight is its velocity perpendicular to its acceleration?
A projectile is launched from a height h above the ground. How does the time of flight compare to a projectile launched from ground level with the same initial velocity and angle?
A projectile is launched from the ground at 50 m/s at an angle of 30°. Calculate the time taken to reach the maximum height. (Take g = 10 m/s², sin 30° = 0.5)
A projectile is launched from the ground at an angle θ with speed u. What is the formula for its horizontal range?
A stone is projected at 40 m/s at an angle of 60° to the horizontal. Calculate the maximum height reached by the stone. (Take g = 10 m/s², sin 60° = 0.866)
A stone is thrown horizontally from a height of 80 m and lands 160 m away. What is the initial speed of the stone? (Take g = 10 m/s²)
Explain why the horizontal and vertical motions of a projectile are independent of each other.
If a projectile is launched with an initial velocity of 20 m/s at an angle of 30° above the horizontal, what is the horizontal component of its initial velocity? (Take cos 30° = 0.866)
If air resistance is not neglected, what effect does it have on the range and maximum height of a projectile?
State two assumptions made in the analysis of ideal projectile motion.
