Biomechanics Practice Questions with Verified
Answers 2025
1: What is biomechanics? - correct answer -
Biomechanics is the study of the mechanical laws relating to the movement or
structure of living organisms.
2: What are the two main branches of biomechanics? - correct answer -
The two main branches are kinematics, which studies motion without considering
forces, and kinetics, which examines the forces causing motion.
3: What is kinematics? - correct answer -
Kinematics is the branch of biomechanics that describes the motion of points,
bodies, and systems without considering the forces that cause them.
4: What is kinetics? - correct answer -
Kinetics is the branch of biomechanics that studies the forces acting on a body and
the changes in motion they produce.
,5: What is the difference between linear and angular motion? - correct answer -
Linear motion occurs in a straight line, while angular motion occurs around an axis
or point.
6: Define the term center of mass.
The center of mass is the point in a body or system where the entire mass can be
considered to be concentrated for the purpose of analyzing motion.
7: What is the significance of the center of gravity in biomechanics? - correct
answer -
The center of gravity is the point where the weight of a body or system is evenly
distributed, and it is crucial for understanding balance and stability.
8: Explain Newtons First Law of Motion in the context of biomechanics. Newtons
First Law, or the law of inertia, states that an object will remain at rest or in
uniform motion unless acted upon by an external force.
9: How does Newtons Second Law of Motion apply to biomechanics? - correct
answer - Newtons Second Law states that the acceleration of an object is directly
, proportional to the net force acting on it and inversely proportional to its mass
(F=ma).
10: What is the role of Newtons Third Law of Motion in biomechanics? - correct
answer - Newtons Third Law states that for every action, there is an equal and
opposite reaction, which is important for understanding interactions between
bodies.
11: What is a free-body diagram? - correct answer -
A free-body diagram is a graphical representation used to visualize the forces
acting on an object.
12: Define torque in biomechanics.
Torque is the measure of the force that can cause an object to rotate about an axis.
13: What is the equation for calculating torque? - correct answer - Torque (? -
correct answer -) is calculated as ? - correct answer - = Force (F) x Lever Arm (r).
14: What is the difference between static and dynamic equilibrium? - correct
answer - Static equilibrium occurs when an object is at rest, and all forces are
