Projectile Motion

What happens to the vertical velocity of a projectile as it rises?

• It remains constant throughout the ascent.

• It increases until it reaches the maximum height.

• It decreases until it reaches the maximum height, where it becomes zero.

• It fluctuates randomly during the ascent.

What factors affect the range of a projectile?

• Initial velocity, launch angle, and height of launch

• Mass of the projectile, air resistance, and temperature

• Wind speed, humidity, and launch angle

• Initial velocity, mass of the projectile, and air pressure

What is the optimal angle for maximum range in projectile motion?

• 30°

• 45°

• 60°

• 75°

What is the range of a projectile?

• The maximum height reached by the projectile.

• The total time the projectile is in the air.

• The horizontal distance traveled by the projectile from the launch point to the landing point.

• The vertical distance traveled by the projectile from the launch point to the landing point.

How does air resistance affect projectile motion?

• Air resistance has no effect on projectile motion.

• Air resistance increases the range of the projectile.

• Air resistance opposes the motion of the projectile, reducing its range and altering its trajectory compared to motion in a vacuum.

• Air resistance causes the projectile to move in a straight line.

What is the acceleration due to gravity?

• 8.9 m/s²

• 9.8 m/s²

• 10.5 m/s²

• 9.0 m/s²

What is the maximum height in projectile motion?

• The maximum height is the highest point reached by the projectile, where the vertical velocity is zero.

• The maximum height is the point where the projectile starts to descend.

• The maximum height is the initial launch height of the projectile.

• The maximum height is the point where the projectile has the greatest horizontal velocity.

What happens to the vertical velocity of a projectile as it falls?

• It remains constant throughout the fall.

• It decreases due to air resistance.

• It increases due to the acceleration of gravity.

• It fluctuates randomly during the fall.

What is the relationship between vertical and horizontal motion in projectile motion?

• Vertical and horizontal motions are dependent on each other; both are affected by gravity.

• Vertical motion has constant velocity while horizontal motion is affected by gravity.

• Vertical and horizontal motions are independent of each other; horizontal motion has constant velocity while vertical motion is affected by gravity.

• Vertical motion is faster than horizontal motion due to gravitational pull.

What is the horizontal component of velocity in projectile motion?

• It increases over time due to horizontal acceleration.

• It decreases over time due to air resistance.

• It remains constant throughout the motion, as there is no horizontal acceleration in ideal conditions.

• It varies depending on the angle of projection.
