Kinetics
Correct Answer
A. MechanicsExplanation
Mechanics is the correct answer because it is the branch of physics that focuses on studying forces and the resulting motion. It involves analyzing the behavior of objects under the influence of various forces, such as gravity or friction. By studying mechanics, scientists can understand and predict how objects will move and interact with each other. Biomechanics, on the other hand, specifically applies the principles of mechanics to the study of biological systems. Statics and kinetics are sub-disciplines of mechanics that deal with the equilibrium of forces and the motion of objects, respectively.Rate this question:

Factors associated with moving systems & can be divided into kinetics and kinematics
- A.
Dynamics
- B.
Mechanics
- C.
Statics
- D.
Kinetics
Correct Answer
A. DynamicsExplanation
The factors associated with moving systems can be divided into two categories: kinetics and kinematics. Kinetics refers to the study of the forces and motion of objects, while kinematics focuses on the description of motion without considering the forces involved. Dynamics encompasses both kinetics and kinematics, making it the correct answer as it encompasses the study of both the forces and motion of moving systems. Mechanics and statics are related fields but do not encompass both kinetics and kinematics, making them incorrect choices.Rate this question:

- A.
Kinematics
- B.
Biomechanics
- C.
Dynamics
- D.
Kinetics
Correct Answer
D. KineticsExplanation
Kinetics is the branch of physics that deals with the forces causing movement in a system. It focuses on the study of the causes of motion, including the forces and torques that act on objects. Kinetics is concerned with the analysis of how objects move and the factors that affect their motion, such as gravity, friction, and applied forces. It is different from kinematics, which is the branch of physics that describes motion without considering the forces causing it. Biomechanics, on the other hand, is the study of the mechanics of living organisms, while dynamics refers to the study of motion and the forces that cause it.Rate this question:

C. KinematicsExplanation
Kinematics is the correct answer because it is the branch of mechanics that deals with the motion of objects without considering the forces that cause the motion. It focuses on the time, space, and mass aspects of a moving system, which are mentioned in the question. Kinematics involves studying concepts such as displacement, velocity, and acceleration to describe and analyze the motion of objects.Rate this question:

Focuses on the manner in which bones move in space without regard to the movement of joint surfaces such as shoulder flexion/extension.
- A.
Osteokinematics
- B.
Arthrokinematics
- C.
Kinetics
- D.
Biomechanics
Correct Answer
A. OsteokinematicsExplanation
Osteokinematics refers to the study of the movement of bones in space, regardless of the movement of joint surfaces. It focuses on the overall motion and position of bones, rather than the specific movements of joint surfaces such as flexion or extension in the shoulder. This term is used to describe the gross movements and range of motion of bones in the body.Rate this question:

Dynamics
- D.
Mechanics
Correct Answer
A. ArthrokinematicsExplanation
Arthrokinematics refers to the study of the movement between the joint surfaces. It focuses on the specific motions and relationships between the adjoining joint surfaces, including how they move in relation to each other. This can involve analyzing the direction and type of movement, such as sliding, rolling, or spinning, that occurs between the joint surfaces. Therefore, arthrokinematics is the most appropriate term to describe the given explanation.Rate this question:

What are the three parts of a lever
- A.
Force
- B.
Axis
- C.
Resistance
- D.
All of Above
Correct Answer
D. All of AboveExplanation
A lever is a simple machine consisting of a rigid bar that rotates around a fixed point called the axis. The three parts of a lever are force, axis, and resistance. The force is the effort applied to the lever, the axis is the point where the lever pivots or rotates, and the resistance is the load or weight being moved. All of these components are necessary for a lever to function properly, making "All of Above" the correct answer.Rate this question:

The middle of a first class lever is a Axis ?
- A.
True
- B.
False
Correct Answer
A. TrueExplanation
In a first-class lever, the axis (or fulcrum) is located in the middle. This means that the effort and the load are on opposite sides of the axis. When the effort is applied, it causes the lever to rotate around the axis, resulting in the movement of the load. Therefore, the statement that the middle of a first-class lever is an axis is true.Rate this question:

Axis
Correct Answer(s)
A. Force
B. Resistance
D. AxisExplanation
A lever is a simple machine consisting of a rigid bar that rotates around a fixed point called the axis. The three essential parts of a lever are: force, which is the effort applied to the lever to make it move; resistance, which is the load or weight being lifted or moved by the lever; and the arm, which is the distance between the axis and the point where the force is applied or the resistance is located. These three parts work together to amplify or change the direction of the force applied to the lever.Rate this question:

What is in the middle of a third class lever?
Correct Answer(s)
ForceExplanation
In a third class lever, the force is located between the fulcrum and the load. The load is the object being moved, the fulcrum is the pivot point, and the force is the effort applied to move the load. The force is positioned closer to the fulcrum than the load, which means that a greater force is required to move the load. Therefore, the force is in the middle of a third class lever.Rate this question:
- 14.
Where is the resistance located in a third class lever
Correct Answer(s)
Opposite endExplanation
In a third class lever, the resistance is located at the opposite end of the lever from the effort. This means that the resistance is positioned farther away from the fulcrum compared to the effort. In this type of lever, the effort is applied closer to the fulcrum, which allows for a greater mechanical advantage. The resistance being located at the opposite end requires more effort to overcome it, but it also allows for a larger range of motion and speed.Rate this question:
- 15.
Where is the axis located in a second class lever?
Correct Answer(s)
At the endExplanation
In a second class lever, the axis is located at the end. This means that the fulcrum or pivot point, around which the lever rotates, is positioned at the end of the lever. Second class levers have the load located between the axis and the effort, which allows for greater force to be applied to the load with less effort. Examples of second class levers include wheelbarrows and nutcrackers.Rate this question:

What is the middle of a second class lever?
Correct Answer(s)
resistanceExplanation
In a second-class lever, the load is located between the effort and the fulcrum. This setup allows for lifting heavy loads with less effort, as seen in wheelbarrows. The arrangement maximizes mechanical advantage by placing the effort further from the fulcrum than the load, making lifting easier with less force.Rate this question:
- 17.
Where is the axis located in a first class lever?
Correct Answer(s)
Between the force and resistance, in between the resistance and forceExplanation
In a first-class lever, the axis is located between the force and resistance. This means that the axis acts as the fulcrum, or pivot point, around which the lever rotates. The force is applied on one side of the axis, while the resistance is located on the other side. This arrangement allows for the force to be multiplied or redirected to overcome the resistance.Rate this question:
