Projectile Motion

What kind of path does a ball follow when thrown at an angle?

• Zigzag

• Straight

• Curved

• Circular

What are the two components of velocity when an object is thrown at an angle?

• Forward and Backward

• Vertical and Diagonal

• Horizontal and Vertical

• Left and Right

What force always acts vertically on a moving object?

• Frictional Force

• Electric Force

• Magnetic Force

• Gravitational Force

Which component of velocity changes due to the effect of gravity?

• Diagonal Component

• Horizontal Component

• Vertical Component

• Circular Component

What is the shape of the trajectory followed by an object in projectile motion?

• Circle

• Ellipse

• Hyperbola

• Parabola

At what angle does a ball achieve maximum range when thrown?

• 30 degrees

• 45 degrees

• 60 degrees

• 90 degrees

What happens to the range of a ball when the angle of projection is increased beyond 45 degrees?

• Increases

• Cannot be determined

• Decreases

• Remains the same

What is the reason behind the maximum range achieved at 45 degrees angle of projection?

• Horizontal velocity decreases

• Vertical velocity increases

• Both factors have a good value

• Time spent in the air decreases

What is the initial vertical component of velocity for both stones thrown in the experiment?

• Zero

• Negative

• Positive

• Variable

What effect does the horizontal velocity have on the travel time of a stone?

• Decreases travel time

• No effect on travel time

• Variable effect

• Increases travel time
