May the force be with you.
Push or a pull exerted on an object in order to change the motion of the object; has size and direction.
What is force?
Energy that is stored.
What is potential energy?
Energy of motion.
What is kinetic energy?
The attraction or repulsion between magnetic poles.
What is magnetic force?
A material in which electric charges CAN move freely.
What is a conductor?
The combination of all of the forces acting on an object.
What is net force?
Energy related to the distance between magnetic materials.
What is magnetic potential energy?
An object at rest stays at rest and an object in motion stays in motion with the same speed and in the same direction unless acted upon by an unbalanced force.
What is Newton's First Law of Motion?
Electric charge at rest; generally produced by friction or induction.
What is static electricity?
A material in which electric charges CANNOT move freely.
What is an insulator?
The tendency of an object to resist a change in motion unless an outside force acts on the object.
What is inertia?
The energy of stretched or compressed objects.
What is elastic potential energy?
For every action there is an equal and opposite reaction.
What is Newton's Third Law of Motion?
Any material that attracts iron or materials containing iron.
What is ferromagnetic?
An element or compound that conducts electric current better than an insulator does but not as well as a conductor.
What is a semiconductor?
The force of attraction between objects due to their masses.
What is gravity?
The energy stored by objects due to their position above Earth's surface.
What is gravitational potential energy?
The acceleration of an object depends on the mass of the object and the amount of force applied. (F=MxA)
What is Newton's Second Law of Motion?
A coil that has a soft iron core and that acts as a magnet when an electric current is in the coil.
What is an electromagnet?
The transfer of heat energy as waves.
What is radiation?
Any region in which a force has an effect.
What is field?
Energy that is due to chemical bonds.
What is chemical potential energy?
The force that resists the movement of a solid object through a liquid or gas.
What is drag? OR What is fluid friction?
A region where a magnetic force can be detected.
What is magnetic field?
The direct transfer of heat from one substance to another substance that it is touching.
What is conduction?
