Access Code (located on the underside of the lid of your lab kit): AC-
KW80U6
Lab Report Format Expectations
Utilize college level grammar and formatting when answering text based
questions.
Report all equations in a proper mathematical format, with the correct signs
and symbols.
Submissions with incomplete or improperly formatted responses may be
rejected.
Pre-Lab Questions
1. In this lab, you will conduct three experiments that will demonstrate
the concepts of work, potential energy and kinetic energy. Briefly
explain those three concepts and their mathematical definitions.
- Work is defined as the force applied to an object multiplied by the
displacement in the direction of the force, and its equation is
W=F⋅d⋅cos(θ).
Where F is the force applied, d is the displacement, and θ is the
angle between the force and displacement.
- Potential Energy (U): Energy stored due to the position of an object. In
the gravitational case, its equation is U=mgh.
Where m is the object’s mass, g is the acceleration due to the
gravity, and h is the object’s height.
- Kinetic Energy (K) is the energy associated with an object's motion,
and its equation is K=1/2mv^2.
Where v is the object's velocity.
