At a roller coaster, energy conversions from potential to kinetic energy and back repeatedly several times across the course of a trip. Kinetic energy is the force that an object possesses as a consequence of its movement.
All moving objects possess kinetic energy, which is defined with the mass and speed of the object. Potential energy is the energy that is deposited in an object due to its position corresponding to some zero point. Gravitational potential energy is highest at the top of the looping point of a roller coaster and smallest at the deepest end.
To find <em>Speed </em>you divide distance by time.
Reasoning:
Displacement is the change in an object's position from the origin.
To find Acceleration you use the equation a=v^2/r
To find Velocity you divide the distance by the time it takes to travel that distance, then you add your direction to it.
<em>To find speed you use distance is over time</em>
Answer:
right A, B, C, D
Explanation:
They ask which statements are true
A) Right. The decrease in amplitude is due to the dissipation of energy by friction and is called damping
B) Right. In resonant processes the amplitude of the oscillation increases, being a forced oscillation
C) Right. In a system with energy loss, the amplitude must decrease, therefore energy must be supplied to compensate for the loss.
D) Right. It is a resonant process the driving force keeps the oscillation of the system
Explanation:
Kohlberg's theory of moral development is a theory that focuses on how children develop morality and moral reasoning. Kohlberg's theory suggests that moral development occurs in a series of six stages. The theory also suggests that moral logic is primarily focused on seeking and maintaining justice.
