Projectile Motion

Which of the following best describes projectile motion?

• A motion that follows a straight-line path under the influence of gravity alone.

• A motion in which an object moves in a curved path due to the combined effects of horizontal motion and free-fall acceleration.

• A motion in which an object moves with constant acceleration in all directions.

• A motion that is influenced only by air resistance and not by gravity.

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

• Initial velocity

• Angle of release

• Air resistance

• Acceleration due to gravity

How does the angle of release affect the height reached by the object?

• The greater the angle of release, the higher the object will reach, with the maximum height at 90°.

• The height remains constant regardless of the angle of release.

• The height is maximum at 45° and decreases for angles lower or higher than this.

• The height increases as the angle increases but starts decreasing after 60°.

How does the angle of release affect the Range (horizontal distance) covered by the object?

• The range increases as the angle increases, reaching its maximum at 90°.

• The range remains the same for all angles of release.

• The range is maximum at 45° and decreases for angles lower or higher than this.

• The range is always greater for higher angles, regardless of the initial velocity.

Which of the following is an example of applying projectile motion in real life?

• Kicking a soccer ball into a goal.

• Riding a bicycle downhill.

• Swimming in a pool.

• Driving a car on a straight road.
