Major forces to consider within sport include:
All the above: Gravity Air resistance Contact between opponents
As a performance coach, telling an athlete their performance was “smooth” or “getting better” would be considered a
Qualitative evaluation
By improving one’s technique, the athlete may reduce
A and B correct A. Injury to himself/herself B. Injury to others
Rotational force is
Torque
The description of motion using distance and velocity is
Kinematics
Measurement is important within biomechanics to
All of the above: Describe how elite performance was achieved Identify why a sports-related injury occurred Describe the current performance level Predict athletic potential
Human movement is a battle between forces and resistance where force is applied at one end of a bone and resistance is applied at the other end
True
To produce large amounts of torque, a large force arm is needed
True
Knowledge of the mechanical principles have allowed the performance in sport to improve
True
Giving advice such as, “Throw harder” is beneficial to the athlete
False
Knowledge of biomechanics is a way to help a coach teach an athlete new skills
True
In order to teach a skill, it is mandatory for the instructor to correct perform the skill

True
General motion is a combination of linear and angular motion
True
The majority of motion that occurs within sports can be classified as static
False
“Apps” and other tools are available that can measure the amount of force produced during specific exercise
True
Linear motion occurs when all points on an object travel in a straight line
True
Which of the following describes the quantity of motion that occurs
Momentum
A force is
All the above: Defined as push or pull Exerted on objects by other objects Causes an object to start, stop, speed up, or slow down
Forces that occur between two objects touching each other are considered
A and C are correct A. Contact forces C. External forces
The equation for calculating acceleration is
velocity / time
An object at rest remains at rest, or in uniform motion in a straight line, unless it is compelled to change by an externally imposed force describes
First law of motion
