the laws of physics and types of motion Flashcards
what are the types of motion?
linear (or translational) motion, angular (or rotational) motion
what is linear motion?
when a body or its collective parts move the same distance, in the same direction, in the same amount of time
what is an example of linear motion?
a hockey puck gliding on the ice in a straight line
what is angular motion?
movement of a body about an axis
what are the different types of angular motion?
rotations of projectiles or other objects, the entire human body, individual body segments
what is an example of rotations of projectiles or other objects?
swing of a hockey stick
what is an example of rotations of the entire human body?
a trampolinist performing rotations during a routine
what is an example of rotations of individual body segments?
throwing motion of a softball pitcher’s arm
