MCQ Questions
1. A projectile launched horizontally from the edge of a cliff is an example of which type of projectile?
A.
Horizontal projectile
B.
Vertical projectile
C.
Oblique projectile
D.
Circular projectile
Correct Answer:
Horizontal projectile
Explanation:
A body projected with an initial velocity only in the horizontal direction is called a horizontal projectile.
2. A ball thrown at an angle of 45° above the horizontal is an example of which type of projectile?
A.
Horizontal projectile
B.
Oblique projectile
C.
Vertical projectile
D.
Uniform circular motion
Correct Answer:
Oblique projectile
Explanation:
A projectile launched at an angle other than 0° or 90° to the horizontal is called an oblique projectile.
3. A stone thrown straight upward is classified as which type of projectile?
A.
Horizontal projectile
B.
Oblique projectile
C.
Vertical projectile
D.
Parabolic projectile
Correct Answer:
Vertical projectile
Explanation:
When the initial velocity is directed vertically upward, the motion is classified as a vertical projectile.
4. In a horizontal projectile, the initial vertical component of velocity is:
A.
Equal to the horizontal component
B.
Zero
C.
Maximum
D.
Greater than the horizontal component
Correct Answer:
Zero
Explanation:
A horizontal projectile is launched only horizontally, so its initial vertical component of velocity is zero.
5. In an oblique projectile, the initial velocity has:
A.
Only a horizontal component
B.
Only a vertical component
C.
Both horizontal and vertical components
D.
No component of velocity
Correct Answer:
Both horizontal and vertical components
Explanation:
An oblique projection is made at an angle to the horizontal, so the initial velocity can be resolved into horizontal and vertical components.
6. Which launch angle with the horizontal represents a vertical projectile?
A.
0°
B.
30°
C.
60°
D.
90°
Correct Answer:
90°
Explanation:
A launch angle of 90° means that the initial velocity is completely vertical, making it a vertical projectile.
7. Which launch angle with the horizontal represents a horizontal projectile?
A.
0°
B.
45°
C.
60°
D.
90°
Correct Answer:
0°
Explanation:
A launch angle of 0° means that the initial velocity is entirely horizontal, so the projectile is horizontal.
8. A football kicked at an angle above the ground is an example of:
A.
A horizontal projectile
B.
An oblique projectile
C.
A vertical projectile
D.
A stationary body
Correct Answer:
An oblique projectile
Explanation:
Since the football is kicked at an angle, its initial velocity has both horizontal and vertical components, making it an oblique projectile.
9. A package released from an aircraft moving horizontally is treated as which type of projectile, neglecting air resistance?
A.
Horizontal projectile
B.
Vertical projectile
C.
Oblique projectile
D.
Circular projectile
Correct Answer:
Horizontal projectile
Explanation:
The package retains the aircraft's horizontal velocity when released, so it undergoes horizontal projectile motion.
10. Which type of projectile is launched with its initial velocity neither purely horizontal nor purely vertical?
A.
Horizontal projectile
B.
Vertical projectile
C.
Oblique projectile
D.
Resting projectile
Correct Answer:
Oblique projectile
Explanation:
An oblique projectile has an initial velocity directed at an angle, so it is neither purely horizontal nor purely vertical.
