BIOS 252 MODULE 2 QUIZ: THE MECHANICS OF THE
HUMAN BODY
1. Physics helps individuals understand:
@ Physics is the study of how things interact and their motions/forces.
Performance of everyday activities depends on the forces and the impact on the
object/individual. The study of time and space is quantum mechanics. The student
of measurements is metrology.
a. Time and Space
b. Measurement
c. How things move and interact
d. Temperature
2. If an individual throws an object onto a steep road, resistance will adjust the
speed of the object. This is known as :
@ Friction is the force that one surface exerts on another due to the roughness of
the surface. In this case, the steep road acts as friction to change the speed of the
object. The roughness of the road changes the friction, which changes the object’s
speed.
a. Weight
b. Friction
c. Volume
d. Path Pattern
, 3. Imagine you are driving down the road, and all of a sudden, an object appears in
the road. To avoid hitting the object, you press the breaks on the car. This applies
a force, the velocity decreases, and the car stops. This activity of velocity change
is known as what?
@ Newton’s Second Law is the Law of Acceleration. It states that when a force
acts on a body, the body accelerates or changes velocity. In addition, a force can
act on a body to slow the velocity or acceleration. When, the break is pressed this
changes the acceleration of the vehicle (the object).
a. Newton’s First Law
b. Newton’s Second Law
c. Newton’s Third Law
d. Newton’s Fourth Law
4. A person swinging a baseball bat during a game acts a vector causing an object
(the baseball) to move or change it’s motion. This is an example of what?
@ A force is an example of a vector quantity, which has magnitude and direction.
This vector quantity causes an object to move or change their motion. In this case,
the baseball bat acts as force to change the baseball’s direction or speed.
a. A force
b. A resistance
c. A change
d. A gravitational pull
