A metal ball is placed in a device with a spring that has been compressed past its equilibrium point so that when the spring is released, it will propel the ball into the air. The device is set up on a table one meter above the floor. Which components make up the initial energy of the system?(1 point)
Responses

spring potential energy and kinetic energy
kinetic energy, spring potential energy, and gravitational potential energy
kinetic energy, spring potential energy, and gravitational potential energy
gravitational potential energy only
gravitational potential energy only
spring potential energy and gravitational potential energy
spring potential energy and gravitational potential energy
The correct response is: kinetic energy, spring potential energy, and gravitational potential energy.
The correct answer is: kinetic energy, spring potential energy, and gravitational potential energy.
The initial energy of the system can be broken down into different components.
1. Spring Potential Energy: The spring is compressed, meaning it has potential energy stored in it due to its deformation. When released, this potential energy is converted into other forms of energy. Therefore, the initial energy of the system includes spring potential energy.
2. Kinetic Energy: When the spring is released, it propels the metal ball into the air, causing it to move. The ball gains kinetic energy as it moves, which is a form of energy associated with its motion. Therefore, the initial energy of the system also includes kinetic energy.
3. Gravitational Potential Energy: The device is set up on a table one meter above the floor, which means the metal ball has gravitational potential energy due to its position above the ground. This potential energy is associated with the ball's height and the gravitational force acting on it. Therefore, the initial energy of the system also includes gravitational potential energy.
Based on the options provided, the correct answer is: kinetic energy, spring potential energy, and gravitational potential energy.
