the unit of work and energy. 1 N • m or 1 kg • m2/s2.

Consists of two or more simple machines put together

Energy cannot be made or destroyed; energy can only be changed from one place to another or from one form to another

the ratio of work output to the work input

States that the net work done on an object is equal to the object’s change in kinetic energy

the scalar product of the force acting on an object and the displacement caused by that force.

Defined as the rate at which work is done, or the rate at which energy is transformed. It is measured in joules per second (J/s), or watts (W).

an object that eases the load by either changing the magnitude or the direction of a force, but does not change the amount of work done

Indicates how “bouncy” or “stiff” a spring is. More specifically, k, is the constant of proportionality between the restoring force exerted by the spring, and the spring’

definition

a unit of power

Energy associated with an object’s position in space, or height in relation to other objects. This is a latent form of energy, where the amount reflects the amount of energy that

Potential energy is based on arbitrary reference energy. This energy can be chosen for convenience, and/or such that the ground relative to the observer is defined as zero

Energy associated with the state of motion

A conserved scalar quantity associated with the state or condition of an object or system of objects. Roughly defined as the capacity for an object or system to do work

The sum of a system’s potential and kinetic energy

the more the spring is displaced, the stronger the force that will pull toward the equilibrium position

Energy stored in a spring. This is a latent form of energy, where the amount reflects the amount of energy that could be released as some other form.
