Physics Chapter 8
linear motion - correct answer ✔What is the motion that travels in a straight
line?
rotational motion - correct answer ✔What is the motion that travels in a
circular motion?
linear speed - correct answer ✔______ is the distance traveled in a straight
line per unit of time.
tangential speed - correct answer ✔_______is the distance traveled in a per
unit of time.
tangent - correct answer ✔The direction of a circular motion is ___________
of the circumference.
rotation or a spin - correct answer ✔When an object travels about an internal
axis, the motion is a ________ or a __________
rotational speed - correct answer ✔Horse A is closer to the axis than Horse
B, but they both have the same __________ in a merry-go-round.
Rotational speed (rpm) - correct answer ✔Revolution per minute are about of
what?
Rotational Inertia - correct answer ✔______ states that a rotation will not
stop unless an outside force acts upon it.
, decreases - correct answer ✔As radical distance increases, tangential speed
______.
increases - correct answer ✔As rotation speed increases, tangential speed
_______.
Tangential acceleration - correct answer ✔_______ is a change in tangential
speed indicates an acceleration in the direction of tangential motion.
Rotational Inertia - correct answer ✔_______states an object rotating an
about axis tends to remain rotating unless interfered with by some external
influence.
greater - correct answer ✔The greater the distance between the bulk of an
object's mass and its axis of rotation, the _____ the rotational inertia.
Torque - correct answer ✔______ is the product of the force and lever-arm
distance, which tends to produce rotation
torque - correct answer ✔Wrenches and wrenches are examples of
_______.
Torque - correct answer ✔______is produced by this turning force and tends
to produce rotational acceleration.
Forces - correct answer ✔______ tend to make things accelerate.
