1. Which of the following statements best describes the Law of Conservation of Energy?
Energy can be created or destroyed, but not transferred.
The total energy in an isolated system remains constant.
Energy is always lost as heat in any process.
Kinetic energy is always converted to potential energy.
2. A roller coaster car is at the top of a hill. At this point, it possesses maximum:
Kinetic energy
Thermal energy
Potential energy
Chemical energy
1. In a closed system, the total amount of energy can increase or decrease over time.
True
False
2. When a ball is thrown upwards, its kinetic energy is converted into gravitational potential energy.
True
False
1. The Law of Conservation of Energy states that energy cannot be created or , but can be transformed from one form to another.
2. A pendulum at its lowest point has maximum energy and minimum energy.
1. Explain the difference between an isolated system and a closed system in the context of energy conservation.
2. Describe how the Law of Conservation of Energy applies to a bouncing ball, considering energy transformations.
1. A 2 kg object is dropped from a height of 10 meters. Assuming no air resistance, calculate its kinetic energy just before it hits the ground. (Use g = 9.8 m/s²)
2. A spring with a spring constant of 200 N/m is compressed by 0.15 meters. What is the elastic potential energy stored in the spring?
