Energy is the ability to do work.
a)
True
b)
False
3.
As energy transformations occur within a system, the total energy of the system ___.
a)
increases
b)
decreases
c)
is transferred out of the system
d)
remains constant
4.
The sum of the kinetic energy and the potential energy of the objects in a system is called _______.
a)
thermal energy
b)
complete energy
c)
energy maximum
d)
mechanical energy
5.
The net work done by a net force acting on an object is equal to the change in the kinetic energy of the object.
a)
Force - Work Theorem
b)
Work - Energy Theorem
c)
Force - Kinetic Energy Theorem
d)
Work - Force Theorem
6.
If a question asks you to calculated the work W done on an object but it doesn't give you the force F or distance d, instead it tell you the mass m and initial and final velocities. What do you do?
a)
Give up
b)
Cry
c)
Use K = 1/2 mv2 because W and K are the same
