Student objectives

[admin]

Students will:
• Measure changes in height of the
body’s center of mass during a vertical
jump.
• Calculate changes in the gravitational
potential energy of the body’s center
of mass during a vertical jump.
• Understand and apply the definition
of work, Work = fd.
• Recognize that work is equivalent to
energy.
• Understand and apply the joule as a
unit of work and energy using
equivalent forms of the joule:
1 J = 1 Nm = 1 (kg)m/s2 _ (m) =
1 (kg)m2/s2
• Apply conservation of work and
energy to analysis of a vertical jump,
including weight, force, height, and
time of flight.
