motion - gensci

translatory motion

• described using linear quantities

• all parts of the body move the same distance in a given time which can be characterized by displacement, velocity, and acceleration.

rectilinear motion

• object in translational is moving in a straight line

curvilinear motion

• object in translational motion is moving along a curved path.

rotational motion

• movement of an object around a fixed axis or centerpoint

• farther from centerpoint = u gotta go faster

• points on the body has the same angular quantities, but linear quantities are varying

linear displacement

• movement of an object in a straight line along a single axis

linear velocities

• how fast an object movies along a straight axis

linear acceleration

• rate of change of velocity

rigid

• does not bend stretch and deform and allat

angular displacement

• change in position of a rotating body expressed as an angle

• radians or degrees

angular velocity

• how fast an object spins w/ the centerpoint

angular acceleration

• rate of change of angular velocity over time

tangential displacement

• linear distance an object moves along the arc of a circular path
