Dear Readers,

Physics is an important subject in preparation for various Competitive exams.To keep a track of your preparation we have designed a small quiz of 10 Basic Level Questions on Projectile Motion. You have 10 minutes to solve the quiz, click the start timer button in order to start the timer and then click on submit button at the end to submit the quiz and view your scores and correct answers.

Q1. At the top of the trajectory of a projectile, the directions of its velocity and acceleration are

•  Perpendicular to each other
•  Parallel to each other
•  Inclined to each other at an angle of 45^o
•  Antiparallel to each other

Perpendicular to each other

Q2. A man projects a coin upwards from the gate of a uniformly moving train. The path of coin for the man will be

•  Parabolic
•  Inclined straight line
•  Vertical straight line
•  Horizontal straight line

Vertical straight line

Q3. A stone is projected with an initial velocity at an angle to the horizontal. A small piece separates from the stone before the stone reaches its maximum height. Then this piece will

•  Fall to the ground vertically
•  Fly side by side with the parent stone along a parabolic path
•  Fly horizontally initially and will trace a different parabolic path
•  Lag behind the parent stone increasing the distance from it

Fly side by side with the parent stone along a parabolic path

Q4. In a projectile motion, the velocity

•  Is always perpendicular to the acceleration
•  Is never perpendicular to the acceleration
•  Is perpendicular to the acceleration for one instant only
•  Is perpendicular to the acceleration for two instants

Is perpendicular to the acceleration for one instant only

Q5. A cricket ball is thrown with a velocity of 15 m/s at an angle of 30^o with the horizontal. The time of flight of the ball will be (g = 10 m/s²)

•  1.5 s
•  2.5 s
•  3.5 s
•  4.5 s

1.5 s

Q6. If t1 be the time taken by a body to clear the top of a building and t2 be the time spent in air, then t2 : t1 will be

•  1 : 2
•  2 : 1
•  1 : 1
•  1 : 4

2 : 1
