Answer the following questions: A. This would happen if you were carrying a moving box at a constant height
A) Give an example of a situation where a force is while walking across the room.
applied to an object and it moves, but the force does B. This happens because the force applied is perpendicular to the objects
no work on the object. motion. Resulting in 0 work being done on the box.
B) Explain why the force does no work on the object.
, Answer the following questions: Your Answer:
A) Describe a situation where a force is exerted on an A. The situation is me sitting in a chair for an hour.
object for a large amount of time but that force does no B. There is gravitational and normal forces at play, but there is no displacement
work. so 0 work is being done.
B) Explain why that force does no work.
Answer the following questions: Your Answer:
In Figure 4.23, a rope pulls a car. A. If the rope pulls the same direction as the displacement.
A) Under what conditions does the rope cause the car B. If the rope pulls the opposite direction of the displacement.
to increase in energy?
B) Under what conditions does the rope cause the car
to decrease in energy?
Answer the following questions: Your Answer:
A) Does the work you do on a book as you lift it onto a A. No
shelf depend on the path that the book takes? B. No
B) On the time it takes? C. Yes
C) On the height of the shelf? D. Yes
D) On the mass of the book?
Give an example of a conservative force. Gravity, electricity, magnetism, and elasticity
Describe the energy transformations in the throwing of The football starts with no energy. When the quarterback picks up the football,
a football. Start with the quarterback picking up the he does work on the football, thereby increasing both the kinetic energy and
football, throwing it downfield, and end with the the gravitational potential energy. During the throw, the kinetic energy of the
football landing incomplete on the ground. football is greatly increased. Once it lets go, the football goes up and increases
in gravitational potential energy and decreases in kinetic energy until it reaches
the top of the path. As it starts to come down, the gravitational potential
energy decreases, and the kinetic energy increases. Once it hits the ground, the
gravitational potential energy has all been converted to kinetic energy. Friction
and heat then take the kinetic energy away from the football as it rolls to a stop.
Answer the following questions: A) It is easier along a zigzag path because the force needed is less. This is
A) Explain why it is easier to climb a mountain in a because the work is being done over a larger distance.
zigzag path rather than one that is straight up the B) The amount of gravitational potential energy is the same in both cases.
mountain.
B) Compare the amount of increase in your gravitational
potential energy in each case.
What is the rate of doing work called? Power
Which TWO of the following choices are units for Horse power & Watts
power?
Energy is classified as two broad types - what are they? Mechanical & Non-Mechanical
(Hint: Kinetic Energy is not one of the answers.)
