Book Final

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)
Direct Current (DC)
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.
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)
Alternating Current(AC)
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
Kinetic Energy kinetic energy= 1/2mv squared
