Question

describe the energy of the weight when its A)pulled back the furthest extent, B)at the bottom of the swing, C)at the highest point on the other side, and D) back at the original side

Answer 1

Step-by-step explanation:

Example ,The energy of a pendulum weight changes as it swings.

Here answers and explanations

A)When the weight is pulled back to the furthest extent, it has maximum potential energy and zero kinetic energy.

B)At the bottom of the swing, the weight has maximum kinetic energy and zero potential energy.

C)When the weight reaches the highest point on the other side, it has maximum potential energy and zero kinetic energy again.

D)As the weight swings back to the original side, it has the same energy as it did at the beginning, with some potential energy and some kinetic energy. Although the weight loses some energy due to friction and air resistance, its total energy should be conserved throughout the swing.

Answer 2

Answer and Explanation:
A) When the weight is pulled back to its furthest extent, the weight has the highest potential energy. This is because at this point, the weight is furthest away from the center of the earth, and so the potential energy due to gravity is maximized.

B) At the bottom of the swing, the weight has the lowest potential energy. This is because at this point, the weight is closest to the center of the earth, and so the potential energy due to gravity is minimized.

C) When the weight is at its highest point on the other side of the swing, the weight has the highest kinetic energy. This is because at this point, the weight has the highest velocity, and kinetic energy is proportional to the square of the velocity.

D) When the weight is back at its original side, the weight has zero kinetic energy. This is because at this point, the weight has come to a stop and is no longer moving. However, the weight still has a non-zero potential energy due to the force of gravity.
