Biomechanics Revision

What is biomechanics?

• The science of human movement

• The study of animal habitats

• The analysis of chemical reactions

• The study of weather patterns

Which of the following is NOT an external force that biomechanics considers in human movement?

• Gravity

• Wind resistance

• Friction

• Blood pressure

Which of the following is NOT a purpose of biomechanics in sports science?

• Understand the causes of technical faults

• Select techniques to improve performance

• Schedule team practices

• Evaluate performance

How can biomechanics help improve an athlete's performance?

• By selecting techniques to improve performance

• By increasing the number of games played

• By reducing the size of the team

• By changing the rules of the sport

Which of the following best defines "mass" as described in biomechanical principles?

• The gravitational pull on an object due to it having mass

• The amount of matter of an object

• A body's reluctance to change its state of motion

• The speed at which an object moves

What is "weight" according to the biomechanical principles?

• The amount of matter of an object

• The force required to move an object

• The gravitational pull on an object due to it having mass

• The energy stored in an object

What is the correct formula for calculating acceleration?

• a = distance / time

• a = (final v – initial v) / time

• a = mass x velocity

• a = force / mass

Momentum is measured in which of the following units?

• m/s

• Kg/m

• Kg/m/s

• N/m

A runner increases their velocity from 2 m/s to 6 m/s in 2 seconds. What is their acceleration?

• 2 m/s²

• 4 m/s²

• 8 m/s²

• 1 m/s²

According to the material, motion is classified based on which of the following?

• The speed of the object

• The color of the object

• The pathway followed by the moving object

• The size of the object
