Kinetic Energy

• The kinetic energy of an object is the energy that it possesses due to its motion. It is defined as the work needed to accelerate a body of a given mass from rest to its stated velocity. Having gained this energy during its acceleration, the body maintains this kinetic energy unless its speed changes.

Equations of Motion

• Equations of motion are equations that describe the behavior of a physical system in terms of its motion as a function of time.

Momentum

• It is the product of the mass and velocity of an object. It is a vector quantity, possessing a magnitude and a direction in three-dimensional space.

Energy

• Energy is the quantitative property that must be transferred to an object in order to perform work on, or to heat, the object. Energy is a conserved quantity; the law of conservation of energy states that energy can be converted in form, but not created or destroyed.

Symmetry

• It is a physical or mathematical feature of the system that is preserved or remains unchanged under some transformation.

Potential Energy

• Potential energy is the energy held by an object because of its position relative to other objects, stresses within itself, its electric charge, or other factors.

Gravitational Potential Energy

• Gravitational potential energy is energy an object possesses because of its position in a gravitational field. The most common use of gravitational potential energy is for an object near the surface of the Earth where the gravitational acceleration can be assumed to be constant at about 9.8 m/s2.

Elastic Energy

• Elastic energy is the mechanical potential energy stored in the configuration of a material or physical system as it is subjected to elastic deformation by work performed upon it. Elastic energy occurs when objects are impermanently compressed, stretched or generally deformed in any manner.
