PQ Chapters 11+12+13

During a sports science class, Samuel is asked to perform a qualitative biomechanical analysis of a basketball player's jump shot. This typically involves

• data collection

• mathematical analysis

• near-laboratory conditions

• descriptive analysis of movement

Ellie is measuring joint angles during a soccer kick using motion-capture video recording and calculating angular velocity. This is an example of:

• quantitative analysis

• qualitative analysis

• both quantitative and qualitative analysis

• neither quantitative nor qualitative analysis

Amelia is training for a weightlifting competition and wants to ensure she uses all possible joint movements to achieve her goal. What will this result in?

• the production of maximum force

• the production of maximum speed

• the production of maximum effort

• the production of maximum inertia

Rohan is practicing his baseball swing and wants to maximize the speed of his bat. He knows that using his joints in order—from largest to smallest—will help him achieve this. What will be the result of this technique?

• speed

• velocity

• acceleration

• torque

Avery is playing soccer and kicks the ball with a certain force for a short period of time. What does the impulse imparted to the ball equal?

• mass multiplied by velocity

• mass multiplied by acceleration

• force multiplied by time

• velocity multiplied by acceleration

Sophia is trying to open a door by pushing it at a point far from the hinges. The turning effect produced by her push is known as

• torque

• velocity

• angular motion

• the resultant force

When a constant force is applied to an object, the resulting acceleration is

• inversely proportional to the object's mass

• unaffected by the object's mass

• equal to the object's mass

• directly proportional to the applied force

During a dance performance, Neha combines her movements by gliding across the stage while also spinning around. This type of movement is usually a combination of linear and rotational motion and is called

• general motion

• resultant motion

• accelerated motion

• projectile motion

While watching a figure skater spin, Ella wonders about the quantity of angular motion contained within the skater. She learns it is equal to the product of the angular velocity multiplied by the moment of inertia. What is this quantity called?

• Linear momentum

• Ergonomic momentum

• Angular momentum

• Functional momentum

Samuel is working on a project to design equipment and devices that assist the human body, including its cognitive abilities, in performing everyday tasks. What field is Samuel working in?

• Biomechanics

• Ergonomics

• Kinestethics

• Quantics
