Quiz zum Vortrag
Which statement is TRUE about an object experiencing a conservative force?
- The total energy is conserved and the work done is independent of the path taken.
- The total energy is conserved and the work done depends only on the path taken.
- The kinetic energy is conserved and the work done is independent of the path taken.
- The potential energy is equal to the kinetic energy, and the work done is independent of the path taken.
- The potential energy is conserved and the work done is path-dependent.
An object starts and ends at the same height, only under the influence of gravity. Which of the following is TRUE about this object?
- Its kinetic energy is unchanged, and the work done by gravity is zero.
- Its kinetic energy is zero, and the work done by gravity is zero.
- Its potential energy is unchanged, and the work done by gravity is nonzero.
- Its total energy is unchanged, and the work done by gravity is maximum.
- Its potential energy is equal to its kinetic energy, and the work done by gravity is zero.
If you toss a ball into the air, and it comes to a stop only because of a conservative force, where did its initial kinetic energy go?
- Into the gravitational potential energy
- It is unchanged
- Heat
- Sound
- Heat and sound
