Is It Possible for the Total Mechanical Energy of a Moving

question 93

Multiple Choice

Is it possible for the total mechanical energy of a moving particle to be negative?

• A)No,because a moving particle has positive kinetic energy.
• B)No,because potential energy cannot have a value more negative than the value of the positive kinetic energy of the particle.
• C)Only if friction is involved.
• D)yes
