what is principle #4?

Impulse

92

the greater the applied impulse the greater the _______

the greater the applied impulse the greater the change in velocity

93

when does force absorption occur?

when momentum must be dissipated over time or distance (requires application of an impulse)

94

what is the fifth principle?

linear motion

95

movement usually occurs in the direction opposite that of the _______ force

movement usually occurs in the direction opposite that of the applied force

96

what is principle #6?

Angular Motion

97

how is angular motion produced

angular motion is produced by the application of a force acting at some distance from an axis, that is, by a torque

98

what is the seventh principle?

angular momentum

99

angular momentum is _____ when an athlete or object is free in the air (i.e., constant after takeoff)

angular momentum is constant when an athlete or object is free in the air (i.e., constant after takeoff)
