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 9
A projectile is launched at an angle θ with speed u. What is the formula for its maximum height?
A projectile is launched horizontally from a height. What is its initial vertical velocity?
Explain why a projectile launched at 60° and one at 30° with the same speed have the same range.
If a projectile is launched at 30° and another at 60° with the same speed, which will have the same range?
A ball is projected horizontally from a table 1.25 m high. How long does it take to hit the ground? (g = 10 m/s²)
A ball is thrown at 10 m/s at 60°. What is its maximum height? (g = 10 m/s², sin 60° = 0.87)
A ball is thrown at an angle of 60° with a speed of 10 m/s. What is its initial vertical velocity? (Use sin 60° = 0.87)
A ball is thrown horizontally at 5 m/s from a 45 m high building. How far from the base will it land? (g = 10 m/s²)

The formula for the range (R) of a projectile launched at speed u and angle θ is R = ________.
The horizontal distance covered by a projectile is called its ________.
The maximum height reached by a projectile depends on its ________ component of velocity.
The only force acting on a projectile (after it is launched and neglecting air resistance) is ________.
True or False: At the highest point of its trajectory, the vertical velocity of a projectile is zero.
True or False: The acceleration of a projectile is always directed downward.
True or False: The horizontal and vertical motions of a projectile are independent of each other.
True or False: The horizontal range of a projectile increases if the acceleration due to gravity decreases.
