Horizontal Projectiles

What is the trajectory shape of a projectile launched horizontally?

• A linear path.

• A circular path.

• A parabolic path.

• An elliptical path.

What is the initial vertical speed of a projectile launched horizontally?

• 0 m/s

• 9.81 m/s

• 5 m/s

• 15 m/s

What factors affect the time a projectile remains in the air?

• The angle of launch and air resistance.

• The height from which it is launched and the acceleration due to gravity.

• The mass of the projectile and the color of the object.

• The speed of the wind and the temperature of the air.

How does the horizontal motion of a projectile differ from its vertical motion?

• Horizontal motion is at constant velocity, while vertical motion is accelerated due to gravity.

• Both horizontal and vertical motions are accelerated due to gravity.

• Horizontal motion is accelerated, while vertical motion is at constant velocity.

• Horizontal motion is influenced by air resistance, while vertical motion is not.

What is the relationship between time of flight and horizontal distance for a projectile?

• Time of flight is directly proportional to horizontal distance.

• Time of flight is independent of horizontal distance; it depends only on the initial height and gravity.

• Time of flight increases with the square of horizontal distance.

• Time of flight is inversely proportional to horizontal distance.

What is the significance of air resistance in projectile motion?

• Air resistance has no effect on projectile motion.

• Air resistance can increase the speed of the projectile.

• Air resistance can reduce the horizontal distance and affect the trajectory of the projectile.

• Air resistance only affects vertical motion.

If a projectile is launched horizontally, what is its vertical displacement after 2 seconds?

• 10 m downward

• 15 m downward

• 20 m downward

• 25 m downward

What is the vertical motion of a projectile influenced by?

• Air resistance

• Gravity

• Initial velocity

• Mass of the projectile

How do you calculate the final velocity of a projectile after a certain time?

• Final velocity = initial velocity + (acceleration × time) for vertical motion.

• Final velocity = initial velocity - (acceleration × time) for vertical motion.

• Final velocity = (initial velocity × time) + acceleration for vertical motion.

• Final velocity = (initial velocity + acceleration) / time for vertical motion.

What is the acceleration due to gravity acting on a projectile in free fall?

• -9.81 m/s²

• -9.00 m/s²

• -10.5 m/s²

• -8.00 m/s²
