Projectile Motion and Adding Vectors Review

What is the shape of the path followed by the objects in the diagram?

• Straight line

• Parabola

• Circle

• Ellipse

If the object is launched at 90°, what will be its horizontal displacement?

• Maximum

• Zero

• Half the maximum

• Double the maximum

Which factor does NOT affect the range of a projectile, as shown in the diagram?

• Angle of launch

• Initial speed

• Mass of the object

• Acceleration due to gravity

Why does the projectile launched at 45° travel farther than the one launched at 90°?

• It has more mass

• It has both vertical and horizontal velocity components

• It is affected less by gravity

• It is launched with less force

What is the main force acting on the projectile after it is launched, as shown in the diagram?

• Friction

• Gravity

• Magnetism

• Tension

Which of the following is true about the horizontal motion of a projectile?

• The horizontal velocity changes due to gravity.

• The horizontal velocity remains constant.

• The horizontal velocity increases over time.

• The horizontal velocity decreases over time.

A projectile is launched from a height with an initial horizontal velocity of 20 m/s. If the projectile flies for 40 seconds, what is its horizontal velocity just before it hits the ground?

• 20 m/s
• 2 m/s
• 800 m/s
• 2 m/s

What happens to the horizontal velocity of a projectile as it travels along the curved path?

• increases

• decreases

• stays the same

• none of these

What angle of launch will give you the GREATEST possible range?

• 45 degrees
• 30 degrees
• 90 degrees
• 60 degrees
