Biomechanics PPT 2

Which of the following factors is crucial for generating maximum force in a sporting context?

• Activating small muscle groups first

• Using a limited number of body parts

• Transferring momentum from one body part to another at peak velocity

• Maintaining an unstable base of support

Which muscle groups should be activated first to generate maximum force?

• Smallest and least powerful muscle groups

• Weakest and smallest muscle groups

• Strongest and largest muscle groups

• Muscle groups with the least range of motion

Why is it important to use as many body parts as possible in generating force?

• To reduce the overall force generated

• To generate force over a shorter length of time

• To generate force over a greater length of time

• To limit the force to specific muscle groups only

Impulse = F x _____

• acceleration

• magnitude

• time

• velocity

FORCE = WHAT X WHAT?

• Mass x Acceleration

• Mass x Radius²

• Displacement/Time

Momentum is a measure of the amount of motion an object has and its resistance to changing that motion. The formula for momentum is

• P=MA

• M=MV

• P=MV

• M=PV

'choking' a cricket bat will

• increase angular velocity

• decrease angular velocity

• increase the moment of inertia

• is an example of a second class lever

The image above is describing which law of motion?

• law of gravitation

• law of acceleration

• law of action-reaction

• law of inertia

The image above best describes:

• Using a follow through to prevent the chances of deceleration and limit force production

• Using as many body parts as possible and starting with the larger and stronger muscle groups first

• Transferring from the largest to the smaller body parts at maximal force production at the optimal timing

• Provide a stable base of support to minimise the chances of forces being lost

In a sporting context, which of the following best defines distance?

• The total ground covered by an athlete during a competition.

• The straight-line measurement from the starting point to the endpoint.

• The time it takes for an athlete to reach their destination.

• The effort exerted by an athlete to complete a task.
