Projectile Motion Quiz

When an object is in projectile motion, which of the following remains constant throughout its flight?

• Horizontal velocity

• Acceleration

• Horizontal displacement

• Kinetic energy

What angle of projection will result in the maximum range for a projectile launched from the same initial velocity?

• 0 degrees

• 45 degrees

• 90 degrees

• It depends on the initial velocity.

Which of the following is true for the horizontal component of velocity in projectile motion?

• It increases with time.

• It remains constant.

• It decreases with time.

• It varies unpredictably.

At the highest point of a projectile's trajectory, which of the following is true about its velocity?

• It is zero.

• It is at its maximum.

• It is equal to the initial velocity.

• It is directed vertically downward.

If you double the initial velocity of a projectile, how does it affect the time of flight, neglecting air resistance?

• The time of flight doubles.

• The time of flight is halved.

• The time of flight remains the same.

• The time of flight quadruples.

In the absence of air resistance, which path does a projectile follow?

• A straight line

• A parabolic path

• A circular path

• An elliptical path

If two projectiles are launched at the same angle but with different initial velocities, which one will have a longer range, assuming no air resistance?

• The one with the higher initial velocity.

• The one with the lower initial velocity.

• Both will have the same range.

• It depends on the angle of projection.

Which component of a projectile's motion is affected by gravity?

• Horizontal motion

• Vertical motion

• Both horizontal and vertical motions

• Neither horizontal nor vertical motions

In a vacuum (no air resistance), how does the horizontal velocity of a projectile change over time?

• It decreases.

• It increases.

• It remains constant.

• It fluctuates.

What is the relationship between the angle of projection and the maximum height reached by a projectile?

• Maximum height is independent of the angle of projection.

• Maximum height increases with a larger angle of projection.

• Maximum height decreases with a larger angle of projection.

• Maximum height is directly proportional to the initial velocity.
