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 projectile is launched horizontally from a height h with speed v. Write the equation for its trajectory (y as a function of x).
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?
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)
If a projectile is launched at an angle θ and another at (90° – θ) with the same speed, their ranges will be: (1) Equal (2) Different (3) Zero (4) Cannot be determined
The horizontal component of velocity for a projectile (ignoring air resistance) is: (1) Constant (2) Increasing (3) Decreasing (4) Zero
Which of the following best describes projectile motion? (1) Motion under the influence of gravity only (2) Motion with constant acceleration in all directions (3) Motion in a straight line (4) Motion with varying mass
Which of the following best represents the acceleration of a projectile at the top of its trajectory? (1) Zero (2) g downward (3) g upward (4) Depends on initial velocity
Projectile motion is an example of ________ motion in two dimensions.
The horizontal range of a projectile depends on its initial speed and ________.
The maximum height reached by a projectile depends on its initial ________ velocity.
The path followed by a projectile is called a ________.
True or False: At the highest point of its trajectory, the vertical component of a projectile's velocity is zero.
True or False: The mass of a projectile affects its time of flight (neglecting air resistance).
True or False: The range of a projectile is maximum when the angle of projection is 45°.
True or False: The velocity of a projectile at the highest point is equal to its initial horizontal velocity.
