Emma lifts a box onto a shelf. Which statement best explains why the box now has gravitational potential energy?
The box will gain kinetic energy if it falls.
A force is required to move the box through a gravitational field.
The strength of a gravitational field is different at different points.
Kinetic energy must be conserved.
Modified True or False:
Benjamin is spinning a bicycle wheel on its internal axis. The wheel is undergoing circular motion.
true
rotational motion
linear motion
vibrational motion
Modified True or False:
Benjamin is studying for his science test and wonders: The SI unit of energy is the watt. Is he correct?
true
joule
newton
pascal
Modified True or False:
Michael is riding his bicycle and notices that his kinetic energy changes more when he increases his speed than when he changes his mass. Is this statement true?
true
mass
work
speed of light

Modified True or False:
When Olivia spins a bicycle wheel by holding its axle, the wheel is rotating on an internal axis and is undergoing circular motion.
(a)
Modified True or False:
Charlotte is learning about energy in her science class. Her teacher asks, "The SI unit of energy is the watt."
(a)
Modified True or False:
Emma is riding her bicycle and notices that her kinetic energy changes more when she increases her speed than when she changes her mass. Kinetic energy is affected more by a change in speed.
(a)
