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 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)
A ball is thrown horizontally from a 20 m high cliff. How long does it take to reach the ground? (Take g = 10 m/s²)
A projectile is launched at 15 m/s at 45°. What is the time of flight? (g = 10 m/s², sin 45° = 0.71)
A projectile is launched at 20 m/s at 0° (horizontally) from a 10 m high platform. How long will it take to hit the ground? (g = 10 m/s²)
A projectile is launched at 20 m/s at 30°. Calculate its horizontal component of velocity. (Use cos 30° = 0.87)
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?
A stone is thrown at 15 m/s at 30°. What is its time of flight? (g = 10 m/s², sin 30° = 0.5)
A stone is thrown upward at 20 m/s. How long will it take to reach its highest point? (g = 10 m/s²)
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?
If a projectile is launched at an angle of 45° with the same initial speed as one launched at 30°, which will have a greater range?
If the initial speed of a projectile is doubled, what happens to its range (assuming the same angle)?
The vertical displacement of a projectile after time t is given by s = ut + (1/2)at². What is the value of 'a' in this equation for a projectile?
What is projectile motion?
What is the acceleration of a projectile in the vertical direction?
