What is the motion of a projectile in the horizontal direction?

• Uniform motion at constant velocity

• Constant acceleration

• Random and irregular motion

• None of the above

What factor affects the vertical motion of a projectile?

• Gravity

• Constant speed

• Initial velocity only

• Air resistance

Which of the following components describes the vertical motion of a projectile?

• It maintains a constant speed throughout the path.

• It is unaffected by any force.

• It is affected by gravity and follows an accelerated motion.

• It is uniform motion.

Which forces act on a projectile in the vertical and horizontal directions?

• Both horizontal and vertical motions are affected by air resistance.

• Friction affects both directions.

• Gravity affects vertical motion, while horizontal motion has no external force.

• Gravity affects both directions equally.

What is the shape of the trajectory of a projectile when only gravity is considered?

• Zigzag motion

• Parabolic curve

• Circular path

• Straight line

What is the relationship between the horizontal and vertical motions of a projectile?

• They cancel each other out.

• They depend on air resistance.

• They are interconnected and proportional.

• They occur independently of each other.

Which factor remains constant in the horizontal motion of a projectile?

• Direction

• Force

• Acceleration

• Velocity

How does the vertical velocity of a projectile change during upward motion?

• It is not affected by gravity.

• It increases due to gravity until the projectile stops.

• It remains constant throughout the motion.

• It decreases due to gravity until it reaches zero at the peak.

How does gravity affect the horizontal motion of a projectile?

• Gravity eliminates all horizontal forces.

• Gravity reduces the horizontal velocity gradually.

• Gravity does not affect horizontal motion.

• Gravity causes horizontal acceleration.

Why do horizontal and vertical motions not interfere with each other?

• They are of equal magnitudes.

• They share the same trajectory path.

• They are influenced by independent forces.

• They occur at different times.
