Disc Golf Guide: The Science Of Flight Quiz

What does a force in physics refer to?

• The speed of an object in a specific direction

• A type of friction

• Any influence that causes an object to change its state of motion

• A measure of weight only

What is torque also known as?

• Rotary force

• Acceleration

• Gravity

• Lift

Which of the following is NOT a force imparted by a player on a disc golf disc?

• Velocity

• Angle

• Spin

• Color

What does drag act in opposition to? Friction

• Acceleration

• Gravity

• Lift

• The relative motion of an object

What is the difference between speed and velocity?

• Speed is the rate of motion, while velocity includes magnitude and direction

• Velocity is a type of speed

• Speed includes direction, but velocity does not

• There is no difference

What can cause a disc to fly farther in a slight headwind?

• Decreased velocity

• Decreased gravity

• Increased lift outweighing drag forces

• Lower air density

What are the two main aerodynamic forces that act on a flying disc?

• Gravity and lift

• Velocity and acceleration

• Drag and lift

• Spin and torque

What does the Center of Pressure (COP) indicate?

• The heaviest part of the disc

• Where drag and lift have the most effect

• The center of mass

• The optimal throwing angle

What effect does spin have on a disc's flight?

• Reduces lift

• Decreases velocity

• Increases gravity

• Has little influence on aerodynamics but affects flight characteristics

What is the advance ratio related to in disc golf?

• The ratio of lift to drag

• The angle of release to distance achieved

• The spin rate relative to velocity

• The disc's weight to air density
