11 HMS - Biomechanics: Absorbing Force

What are the two types of forces studied in HMS?

• Gravitational and Magnetic

• Applied and Reaction

• Frictional and Tension

• Electrical and Nuclear

What is an example of an internal force?

• Gravity

• Air resistance

• Contraction of the quadriceps

• Friction

What type of power should a weightlifter focus on developing?

• Speed-dominated power

• Endurance power

• Strength-dominated power

• Flexibility power

What is the result when a runner applies force to a track surface?

• The runner slows down

• The runner jumps higher

• The runner propels their body along the track

• The runner remains stationary

How does the body absorb forces during activities like rebounding in basketball?

• By stiffening the joints

• By bending or flexing the joints

• By relaxing the muscles completely

• By increasing body weight

What happens if the knees are not bent during landing?

• The risk of injury to the joint decreases

• The muscles contract more

• The risk of injury to the joint increases

• The body absorbs more force

Which muscles lengthen while absorbing force during the landing phase of a long jump?

• Hamstrings

• Calves

• Quadriceps

• Biceps

What is the impact felt by an object being caught a product of?

• The force of the ball and the speed of the ball

• The distance through which the hands move and the speed of the ball

• The force of the ball and the distance through which the hands move

• The speed of the ball and the size of the ball

Which technique can help increase the catching distance when catching a ball?

• Keeping the arms close to the body

• Smothering the ball with the other hand

• Using only one hand to catch

• Standing still while catching

What is the effect of applying a greater force to an object?

• The object moves slower

• The object remains stationary

• The object accelerates more

• The object decreases in size
