inertia
the tendency of an object to resist changes in its state of motion
inertia
This is the energy an object has due to its position or condition.
Potential energy is the stored energy an object possesses because of its position, arrangement, or state. It has the potential to do work when the position or condition changes, like a rock held at a height or a compressed spring.
This is the energy an object has due to its motion.
Kinetic energy is the energy that an object possesses because it is moving. The faster an object moves, the more kinetic energy it has. It depends on both the mass of the object and its speed.
This is the energy stored in an object due to its position or configuration.
Potential energy is the energy an object has because of its position or state. For example, a rock held at a height has gravitational potential energy because of Earth's gravity pulling on it. This energy can be released and converted into other forms, like kinetic energy when the rock falls.
This principle explains that in a frictionless system, the sum of kinetic energy and potential energy remains constant, meaning energy shifts between forms but the total never changes.
Mechanical energy conservation means the total energy from motion (kinetic) and position (potential) stays the same if no energy is lost. Energy just changes between these forms.
newtons first law of motion is also known by this term
object in motion stays in motion with the same speed and in same direction unless acted upon by net force and a object in rest will stay at rest
The potential energy of an object due to its height above a reference level.
Gravitational potential energy is the energy stored in an object as a result of its vertical position or height relative to a reference point, usually the ground. The higher the object, the more gravitational potential energy it has, because gravity can pull it down and convert that energy into motion.
The formula for kinetic energy includes this term, which represents the mass of the object.
In the kinetic energy formula (KE = 1/2 * m * v²), 'm' stands for the mass of the object. Mass is a measure of how much matter an object contains, and it directly affects the amount of kinetic energy the object has.
This energy comes from the movement of tiny particles like atoms and molecules.
Thermal energy is the total energy of all the particles in an object due to their motion. When particles move faster, the object feels hotter. This energy can transfer from one object to another as heat, causing temperature changes.
When a roller coaster moves along its track, this law explains why the coaster speeds up as it goes downhill and slows down going uphill, due to the interchange of gravitational potential energy and kinetic energy.
A roller coaster shows this by turning height energy (potential) into speed energy (kinetic) and back as it goes up and down.
Inertia is directly proportional to this property of an object.
What is mass? The more massive an object is, the more inertia it has, meaning it resists changes in motion more.
The formula for gravitational potential energy includes this term, which represents the acceleration due to gravity.
The 'g' in the gravitational potential energy formula (PE = mgh) stands for the acceleration due to gravity, which is approximately 9.8 meters per second squared on Earth. It represents how fast an object accelerates when falling freely under gravity.
The kinetic energy of an object increases with the square of this quantity.
Kinetic energy increases with the square of velocity, meaning if you double the speed of an object, its kinetic energy becomes four times greater. This shows how important speed is in determining kinetic energy.
This form of energy is carried by light and other electromagnetic waves.
Radiant energy is energy that travels in waves, such as visible light, radio waves, or X-rays. It can move through space and does not require a medium. The Sun's energy reaching Earth is an example of radiant energy.
This type of energy, often lost as heat due to friction or air resistance, demonstrates that while total energy is conserved, usable mechanical energy can decrease in real-world systems.
Friction and air resistance turn some mechanical energy into heat, so not all energy stays useful for motion.
A stationary object will remain at rest unless acted upon by this.
What is an unbalanced force? An unbalanced force is a force that causes a change in an object's motion.
A stretched rubber band has this type of potential energy.
Elastic potential energy is the energy stored in objects that can be stretched or compressed, like a rubber band or spring. When the object returns to its original shape, this stored energy is released, often causing motion or force.
This type of energy is converted into kinetic energy when a roller coaster goes downhill.
As a roller coaster descends, its stored potential energy (from being at a height) converts into kinetic energy, causing it to speed up. This transformation illustrates how energy changes forms but the total energy remains constant.
This energy is stored in the bonds between atoms in molecules.
Chemical energy is stored in the connections between atoms in substances. When these bonds break or form during chemical reactions, energy is released or absorbed. For example, food contains chemical energy that our bodies convert to fuel.
In an isolated system, this quantity measures the total energy, including kinetic, potential, thermal, and other forms, remaining constant despite energy changing forms
Total energy in a system stays constant but can change forms like from chemical to mechanical or thermal energy.
This is what happens to a ball rolling across a level surface if no force acts on it.
What is it continues to roll at constant velocity? If there's no friction or air resistance, the ball will keep rolling at the same speed and in the same direction forever, due to inertia.
This type of potential energy is stored in the bonds of atoms and molecules.
Chemical potential energy is the energy stored within the chemical bonds of substances. This energy can be released during chemical reactions, such as when fuel burns or food is digested, providing energy for various processes.
An object at rest has this amount of kinetic energy.
An object that is not moving has zero kinetic energy because kinetic energy depends entirely on motion. Without motion, there is no kinetic energy to measure.
This is the energy associated with moving electric charges.
Electrical energy results from the flow of electrons through a conductor, like wires. This energy powers devices like lights and computers. It can be generated from various sources such as batteries or power plants.
This experiment or device is commonly used to demonstrate the conservation of energy by showing the transformation of energy between potential and kinetic forms with minimal losses.
Pendulums and Newton’s cradle show energy changing between kinetic and potential energy, demonstrating conservation clearly.
