What is the primary factor that determines the range of a projectile?

  1. Initial velocity

  2. Mass of the projectile

  3. Air resistance

  4. Angle of projection


Correct Option: D
Explanation:

The angle at which a projectile is launched significantly influences its range. A projectile launched at a higher angle will travel farther than one launched at a lower angle, assuming other factors remain constant.

What is the term used to describe the curved path that a projectile follows?

  1. Trajectory

  2. Parabola

  3. Hyperbola

  4. Ellipse


Correct Option: A
Explanation:

The path that a projectile follows is called its trajectory. It is typically a curved path due to the influence of gravity.

Which of the following is NOT a type of ballistic coefficient?

  1. Sectional density

  2. Form factor

  3. Drag coefficient

  4. Mass


Correct Option: D
Explanation:

Mass is not a type of ballistic coefficient. Sectional density, form factor, and drag coefficient are all factors that contribute to a projectile's ballistic coefficient.

What is the term used to describe the time it takes for a projectile to reach its maximum height?

  1. Time of flight

  2. Ascent time

  3. Descent time

  4. Hang time


Correct Option: B
Explanation:

Ascent time refers to the time it takes for a projectile to reach its maximum height.

What is the maximum height that a projectile can reach?

  1. Dependent on initial velocity only

  2. Dependent on angle of projection only

  3. Dependent on both initial velocity and angle of projection

  4. Independent of initial velocity and angle of projection


Correct Option: C
Explanation:

The maximum height reached by a projectile depends on both its initial velocity and the angle at which it is projected.

Which of the following factors does NOT affect the velocity of a projectile?

  1. Air resistance

  2. Gravitational acceleration

  3. Mass of the projectile

  4. Initial velocity


Correct Option: C
Explanation:

The mass of the projectile does not directly affect its velocity. Air resistance, gravitational acceleration, and initial velocity all influence the velocity of a projectile.

What is the term used to describe the point at which a projectile reaches its maximum height?

  1. Apex

  2. Vertex

  3. Peak

  4. Summit


Correct Option: A
Explanation:

The apex is the highest point reached by a projectile during its flight.

Which of the following is NOT a type of projectile motion?

  1. Horizontal projection

  2. Vertical projection

  3. Curved projection

  4. Oblique projection


Correct Option: C
Explanation:

Curved projection is not a type of projectile motion. Horizontal projection, vertical projection, and oblique projection are all types of projectile motion.

What is the term used to describe the angle between the horizontal and the path of a projectile?

  1. Angle of elevation

  2. Angle of depression

  3. Angle of attack

  4. Angle of incidence


Correct Option: A
Explanation:

The angle of elevation is the angle between the horizontal and the path of a projectile.

Which of the following is NOT a type of ballistic trajectory?

  1. Flat trajectory

  2. Curved trajectory

  3. Parabolic trajectory

  4. Hyperbolic trajectory


Correct Option: D
Explanation:

Hyperbolic trajectory is not a type of ballistic trajectory. Flat trajectory, curved trajectory, and parabolic trajectory are all types of ballistic trajectories.

What is the term used to describe the point at which a projectile strikes a surface?

  1. Impact point

  2. Target point

  3. Hit point

  4. Strike point


Correct Option: A
Explanation:

The impact point is the point at which a projectile strikes a surface.

Which of the following factors does NOT affect the time of flight of a projectile?

  1. Initial velocity

  2. Angle of projection

  3. Gravitational acceleration

  4. Air resistance


Correct Option: D
Explanation:

Air resistance is the only factor that does not directly affect the time of flight of a projectile.

What is the term used to describe the horizontal distance traveled by a projectile?

  1. Range

  2. Displacement

  3. Distance

  4. Flight path


Correct Option: A
Explanation:

The range is the horizontal distance traveled by a projectile.

Which of the following is NOT a type of ballistic weapon?

  1. Rifle

  2. Pistol

  3. Shotgun

  4. Crossbow


Correct Option: D
Explanation:

Crossbow is not a type of ballistic weapon. Rifles, pistols, and shotguns are all types of ballistic weapons.

What is the term used to describe the study of the motion of projectiles?

  1. Ballistics

  2. Kinematics

  3. Dynamics

  4. Projectile motion


Correct Option: A
Explanation:

Ballistics is the study of the motion of projectiles.
