Potential and Kinetic Energy
Potential energy is stored energy. Often, the energy is stored due to an object's position, such as its position above the ground. The amount of potential energy depends on the height of the object above the ground. The amount of potential energy also depends on the mass of the object.
kinetic energy is energy of motion. Objects in motion have kinetic energy. Kinetic energy depends on how fast the object is moving. Kinetic energy also depends on the mass of the object.
When an object is up high, it has potential energy. If it falls or rells downward, its potential energy is converted to kinetic energy as it falls or rolls downward. As its kinetic energy increases, it s, its speed increases.
Imagine a ball rolls down a hill. Its potential energy decreases, and its kinetic energy increases.
Now Imagine that ball hits a plastic cup at the bottom of the hill. The ball's kinetic energy can be used to move that cup. The more kinetic energy the ball has, the more it can move the cup it hits at the bottom of the hill
1. How will changing each property affect the potential energy of an object? 2 points)
1. Changing the height of the object above the ground will directly affect the potential energy. The higher the object is, the greater its potential energy will be.
2. Changing the mass of the object will also affect the potential energy. The greater the mass of the object, the greater its potential energy will be.
Ty!
1. Changing the height of the object: Increasing the height of the object will increase its potential energy, while decreasing the height will decrease its potential energy. This is because the potential energy is directly proportional to the height above the ground.
2. Changing the mass of the object: Increasing the mass of the object will increase its potential energy, while decreasing the mass will decrease its potential energy. This is because the potential energy is directly proportional to the mass of the object.
In summary, both increasing the height and mass of an object will increase its potential energy, while decreasing these properties will decrease its potential energy.
To answer the first question, changing each property can affect the potential energy of an object in the following ways:
1. Changing the height: The potential energy of an object is directly proportional to its height above the ground. As the height increases, the potential energy also increases, and as the height decreases, the potential energy decreases. For example, if you lift a book higher above the ground, its potential energy increases.
2. Changing the mass: The potential energy of an object is also directly proportional to its mass. If you increase the mass of an object while keeping its height constant, the potential energy will increase. On the other hand, if you decrease the mass, the potential energy will decrease. For instance, if you have two books at the same height, the book with more mass will have greater potential energy compared to the book with less mass.
