Potential and Kinetic Energy

Question 1

Read about Pendulums. Then complete the sentences based on the diagram of the pendulum. Be sure to keep this article open because there will be several questions related to it. The pendulum has the most potential energy . The pendulum has the least kinetic energy . The pendulum has the most kinetic energy . The pendulum has the least potential energy .

Selection 1: at the top of swing; Selection 2: at the top of swing; Selection 3: at the bottom of swing; Selection 4: at the bottom of swing

Question 2

When you view the pendulum’s swing, it shows that at the very top of the swing KE = 0. What does that tell you about the pendulum’s motion at that point?

Revolt · Accepted Answer

If the kinetic energy is zero, it means that the pendulum has no velocity and is not moving. At the very top of its swing, the pendulum stops for a brief moment before it begins to swing back down in the opposite direction.

increases

Question 4

Click the “step” button on the simulation to observe the energy at different points on the roller coaster ride. Use the information from the pie chart in the simulation to complete the sentences. Kinetic energy is greatest at . Potential energy is greatest at . Kinetic energy decreases while potential energy increases between steps .

Question 6

Explain why the roller coaster’s potential energy is greater at point 1 than at point 4.

Revolt · Accepted Answer

Gravitational potential energy depends on the height of the object. Since point 1 is higher than point 4, the roller coaster has more potential energy at point 1 than at point 4.

Question 7

What did you include in your response? Check all that apply.

Revolt · Accepted Answer

Zero kinetic energy means the pendulum is not moving.; The pendulum stops at the top of the swing.
