Biomechanics Quiz

Biomechanics is (a)   .

• The study of biological actions and
• The management of injuries in sport
• The design of training plans to imp
• The analysis of factors influencing

Answer explanation

Biomechanics is the study of biological actions and structures of the body and the forces they produce, making it the correct choice.

What does kinematics in biomechanics describe?

• How far, how fast and how consistently a body moves

• The internal and external forces acting on the body

• The strategies for the management of injuries

• The factors influencing movement and patterns of participation

Answer explanation

Kinematics in biomechanics describes how far, how fast, and how consistently a body moves.

What is the difference between speed and velocity?

• Speed is the distance covered divided by the time taken, while velocity is the displacement of the body divided by the time taken

• Speed is the rate at which an object's velocity changes over time, while velocity is the mass of the body traveling multiplied by the velocity

• There is no difference; speed and velocity are the same

Answer explanation

Speed is the distance covered divided by the time taken, while velocity is the displacement of the body divided by the time taken

How is acceleration defined in the context of linear kinematics?

• The length of the path through which a body travels

• The displacement of the body divided by the time taken

• The rate at which an object's velocity changes over time

• The mass of the body traveling in a straight or curved line multiplied by the velocity

Answer explanation

Acceleration is defined as the rate at which an object's velocity changes over time.

What is momentum as defined in the table?

• The length of the path through which a body travels

• The rate at which an object's velocity changes over time

• The mass of the body traveling in a straight or curved line multiplied by the velocity

• The displacement of the body divided by the time taken

Answer explanation

Momentum is defined as the mass of the body traveling in a straight or curved line multiplied by the velocity.

Linear motion is described as (a)   in terms of movement.

• Movement in a random pattern
• Movement along a circular pathway
• Movement along a line
• Movement at varying speeds

Answer explanation

Linear motion is described as movement along a line, making it the correct choice out of the options provided.

Which term is used to describe linear motion that takes place in a straight line? (a)  

• Curvilinear motion
• Angular motion
• General motion
• Rectilinear motion

Answer explanation

Rectilinear motion is the term used to describe linear motion that takes place in a straight line.

What is curvilinear motion?

• Linear motion in a straight line

• Linear motion in a curved path

• Angular motion around a fixed point

• General motion combining linear and angular motion

Answer explanation

Curvilinear motion refers to linear motion in a curved path, making it the correct choice in this context.

What type of motion is described as angular or rotary?

• Movement along a line

• Movement along a circular path about some fixed point

• Movement in a straight line at the same speed

• Movement in a random pattern

Answer explanation

Angular or rotary motion is described as movement along a circular path about some fixed point.

Which of the following is an example of angular motion in sports?

• Running in a straight line

• Rotation around the high bar in gymnastics

• The linear motion of a sprinter

• Walking in a straight line

Answer explanation

Rotation around the high bar in gymnastics involves angular motion, unlike running or walking in a straight line which are linear motions.
