Study Notes
Energy
Types of Energy
-
Kinetic Energy: the energy of motion
- Associated with an object's motion
- Depends on the object's velocity
- Formula: KE = 1/2 * m * v^2 (where m is mass and v is velocity)
-
Potential Energy: the energy of position or stored energy
- Associated with an object's position or state
- Depends on the object's height, stretch, or configuration
- Types:
-
Gravitational Potential Energy: energy due to an object's height or position in a gravitational field
- Formula: U = m * g * h (where m is mass, g is acceleration due to gravity, and h is height)
-
Elastic Potential Energy: energy stored in stretched or compressed materials
- Formula: U = 1/2 * k * x^2 (where k is the spring constant and x is the displacement)
-
Gravitational Potential Energy: energy due to an object's height or position in a gravitational field
Key Concepts
- Energy can be converted from one form to another, but the total energy remains constant (Law of Conservation of Energy)
- Kinetic energy can be converted to potential energy, and vice versa
- Energy can be transferred from one object to another through work or heat
Energy
Types of Energy
- Kinetic Energy is the energy of motion, depending on an object's velocity.
- It is associated with an object's motion, and its formula is KE = 1/2 × m × v^2, where m is mass and v is velocity.
- Potential Energy is the energy of position or stored energy, depending on an object's height, stretch, or configuration.
- There are two types of Potential Energy: Gravitational Potential Energy and Elastic Potential Energy.
- Gravitational Potential Energy is the energy due to an object's height or position in a gravitational field, with the formula U = m × g × h, where m is mass, g is acceleration due to gravity, and h is height.
- Elastic Potential Energy is the energy stored in stretched or compressed materials, with the formula U = 1/2 × k × x^2, where k is the spring constant and x is the displacement.
Key Concepts
- The Law of Conservation of Energy states that energy can be converted from one form to another, but the total energy remains constant.
- Kinetic energy can be converted to potential energy, and vice versa.
- Energy can be transferred from one object to another through work or heat.
