A toy robot can walk and talk and runs on batteries. Which type of energy is stored in the batteries?
nuclear
chemical
electrical
mechanical
How is mechanical energy calculated?
by adding potential energy and kinetic energy
by dividing potential energy by kinetic energy
by multiplying potential energy and kinetic energy
by subtracting potential energy from kinetic energy
Which of these is an example of the transformation of gravitational potential energy to kinetic energy?
a person walking up a hill
a person skiing down a hill
a car racing around an oval track
A ski lift taking a skier to the top of a mountain
Which of the statements below correcly shows the equation for Work and it's units.
Force (N•m) = Work (J) x Distance (m)
Work (N) = Force (J) x Distance (m)
Distance (m) = Work (N•m) x Force (J)
Work (J) = Force (N) x Distance (m)
The diagram shows a swinging pendulum. During every swing, the pendulum's speed and position change. Three positions during the swing are identified as Position 1, Position 2, and Position 3. At which point would most of the pendulum's potential energy have been turned into kinetic energy?
Position 1
Position 2
Position 3
The potential and kinetic energies are equal in all positions
Which term describes the energy that is stored due to the height of an object above the ground?
kinetic energy
chemical energy
mechanical energy
gravitational potential energy
Elastic Potential Energy is _____________________________________.
the ability of a material to return to its original shape after it has been stretched or deformed.
potential energy that is stored due to the deformation of an elastic object, such as a stretched rubber band.
energy stored in the bonds of chemical compounds. Chemical energy is released during chemical reactions.
the energy contained within a system that is responsible for its temperature.
the flow of thermal energy.
Energy is different from work because:
Energy is the ability to do work, while work is the transfer of energy.
Work is the ability to do energy, while energy is the transfer of work.
Energy and work are exactly the same in all situations.
Work is stored, while energy is always used up.
Two movers use a ramp to load a piano into a truck. Which of the following best describes the potential energy and kinetic energy of the piano as it is moved into the truck?
The potential energy and the kinetic energy equal 0.
The kinetic energy is 0 and the potential energy is decreasing.
The piano has kinetic energy and the gravitational potential energy is increasing.
The piano has kinetic energy and the gravitational potential energy is decreasing.
