Speed/Average Speed | The distance traveled divided by the time interval during which motion occurred. |
Force | A push or pull on an object. |
Gravitational Force | |
Elastic Potential Energy | An object has elastic potential energy when it has been stretched or compressed. |
Potential Energy | The energy an object has because of its position, condition, or chemical composition. |
Output Force(load) | |
Insulator | |
Direct Current (DC) | |
Circuit | |
Magnetic Field | |
Velocity | The speed of an object in a particular direction. |
Net Force | The combination of all of the forces acting on an object. |
Kinetic Energy | The energy of an object that is due to the objects motion. |
Gravitational Potential Energy | An object has gravitational potential energy due to its position above the ground. |
Fulcrum | The point on which a lever pivots. |
Work | The transfer of energy to an object by using a force that causes the object to move in the direction of the force. |
Semiconductor | An element or compound that conducts electric current better than an insulator does but not as well as a conductor does. |
Resistance | In physical science the opposition presented to the current by a material or device. |
Series Circuit | A circuit in which the parts are joined one after another such that the current in each part is the same. |
Electromagnetic | |
Acceleration | The rate at which velocity changes over time. |
Inertia | The tendency of an object to resist a change in motion unless an outside force acts on the object. |
Chemical Potential Energy | |
Mechanical Energy | The sum of an objects kinetic energy and potential energy due to gravity or elastic deformation. |
Input Force (effort) | |
Conductor | |
Alternating Current(AC) | |
Load(circuit) | |
Parallel Circuit | A circuit in which the parts are joined in branches such that the voltage across each part is the same. |
Permanent Magnet | |
Average Speed | Average Speed= distance/ time |
Acceleration | Average Time= (final velocity- starting velocity)/ time |
Net Force | 1 N+ 2 N= 3 N |
Force | |
Kinetic Energy | kinetic energy= 1/2mv squared |
