what is the branch of classical Dynamics
mechanics concerned with the study
of forces and their effects on motion
called?
what is the simple definition of a A push or a pull
force?
What is the more complex definition a force is an action exerted on an object that may
of a force? change the motion of an object
What is the unit for force, and what is Newtons (N); 1N=kgm/s2
its relationship to the fundamental
units?
What is an agent of a force? the specific, immediate, and identifiable cause of a
force
When a soccer player kicks a soccer the players foot
ball, what is the agent of the force
applied to the soccer ball?
,There are two kinds of forces. What contact and field
are they?
Differentiate between contact and For contact forces, the agent and receiver of the
field forces force must touch; for field forces, no contact is
needed
Give an example of a contact force typing on a keyboard
Give an example of a field force Magnetism, gravity, and electricity
What are the parts of a free body You draw the object and all of the forces acting on
diagram? the object
What is the property of an object Inertia
that resists any change in its motion?
What is the other name of Newton's Law of Inertia
First Law of motion?
What is the other name Newton's Law of Acceleration
Second Law of Motion?
What is the other name of Newton's Law of Interaction
Third Law of Motion?
Which of the following statements is For every action, there is an equal but opposite
NOT part of Law on Inertia? reaction
Which of the following is NOT a Is directly proportional to the velocity of the
description of acceleration system
according to Newton's Second Law
of Motion?
, Which of the following is NOT true Actions and reaction act on the same system
actions and reactions according to
the Law of Interaction?
What is the equation associated with Fnet = ma
the Law of Acceleration?
What is the reaction to a person The desk applies a force to the person's hand
punching a desk?
What is the reaction to the gravity The leaf pulls up on the Earth
pulling down on a falling leaf?
Differentiate between weight and The weight of an object is a measure of the pull of
mass gravity on that object, while the mass of an object
is the measure of the amount of material in an
object.
What is the mathematical relationship W = mg
between weight and mass
What is the weight of a 91.3 kg ball? W = mg
W = (0.0913 kg) (9.80 m/s2)
W = 0.895 N
What is the mass of a 954.6 kg 954.6 kg
elephant
What is the mass of a 282,000 N w = mg
rocket? m = W/g
m = 282000 N/9.80 m/s2
m = 28775.5
m = 28,800 kg
