ANGULAR KINEMATIC Flashcards
For angular kinematic, _ force is applied, and therefore torque is present.
eccentric
what is angular displacement
the angle formed between the final position and the initial position of a rotating line
s curvilinear displacement Is proportional to
angular displacement and depend on how far away the point is from the axis of rotation
angular velocity is a vector or a scalar quantity
vector
a point further than another on a golf club undergo more, same or less angular displacement
All points on a golf club undergo the same angular displacement, and thus the same average angular velocity, because they all take the same time to undergo that displacemen
a point closer to the golf club head (farther from the axis of rotation) moves through a shorter, longer, same arc length than a point farter from the club head (closer to axis of rotation)
longer
a point farther of a golf club head need to have a faster, same, slower linear speed ( tangential linear velocity) than a point closer
faster because it moves a longer distance but in the same time
what happen with the linear velocity of an object if there is an increase in angular velocity of a spinning object
increase
what is a tangential acceleration
A point on a rotating object undergoes a linear acceleration tangent to its rotational path and equal to the angular acceleration of the object times the radius.
Does a point on a rotating object experience any linear acceleration if the object spins at a constant angular velocity with no angular acceleration?
yes, A point on an object spinning at constant angular velocity follows a circular path, it is constantly changing direction and is thus experiencing a constant linear acceleration.
linear acceleration occurs when
if a object speed up, slow down or change direction
