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 11
A ball is projected with a velocity of 10 m/s at 45°. Calculate its maximum height. (g = 9.8 m/s², sin 45° = 0.707)
A ball is thrown at 20 m/s at an angle of 0° (horizontally) from a 10 m high platform. How long will it take to hit the ground? (g = 9.8 m/s²)
A ball is thrown horizontally from the top of a 20 m high building. How long does it take to reach the ground? (Take g = 9.8 m/s²)
A ball is thrown with a speed of 12 m/s at 60° above the horizontal. What is its initial horizontal velocity? (cos 60° = 0.5)
A projectile is fired at an angle of 53° with a speed of 40 m/s. What is the horizontal component of its velocity? (cos 53° = 0.6)
A projectile is launched at 37° with a speed of 50 m/s. Calculate the time of flight. (g = 9.8 m/s², sin 37° = 0.601)
A projectile is launched at 60° with a speed of 25 m/s. What is its horizontal range? (g = 9.8 m/s², sin 120° = 0.866)
A projectile is launched at an angle of 30° with a speed of 20 m/s. What is the initial vertical component of its velocity? (Use sin 30° = 0.5)
A projectile is launched horizontally from a height h with speed v. Write the equation for its trajectory (y as a function of x).
A stone is thrown horizontally with a speed of 15 m/s from a cliff 45 m high. How far from the base of the cliff will the stone land? (g = 9.8 m/s²)
Describe the effect of increasing the angle of projection from 0° to 90° on the range of a projectile (assuming constant speed).
Explain why the horizontal and vertical motions of a projectile are independent of each other.
If a projectile is launched at an angle θ with initial speed v, what is the formula for its maximum height?
