4.3.12 - Bernoulli Principle & Projectile Motion in Sporting Activities

All athletic events take place in a fluid environment

• True

• False

An object travelling through fluid will always move toward the side with high velocity & low pressure

• True

• False

If air flow velocity increases, air pressure will also increase

• True

• False

If air flow velocity decreases, air pressure will increase

• True

• False

Lift force is _________ to drag

• Parallel

• Linear

• Perpendicular

• None of the Above

"The pressure exerted by a fluid is inversely proportional to its velocity" - This statement describes:

• Lift

• Drag

• Magnus Effect

• Bernoulli's Principle

What describes the curved path that is observed by a spinning projectile?

• Lift

• Drag

• Magnus Effect

• Bernoulli's Principle

According to Bernoulli's Principle, a golf ball hit with backspin will see the ball experience:

• Less air pressure below the ball & travel through the air longer

• Less air pressure above the ball & travel through the air longer

• Less air pressure below the ball & travel through the air for shorter time

• Less air pressure above the ball & travel through the air for shorter time

As the golf ball travels with backspin it will experience:

• Higher air pressure below the ball and lower air pressure above the ball

• Higher air pressure above the ball and lower air pressure below the ball

• Higher air pressure above & below the ball

• Lower air pressure above & below the ball

The ball is attracted to the area of ________________ which results in lift

• Higher air pressure

• Lower air pressure

• Symmetrical air pressure
