law of inertia
every object continues in a state of rest, or of motion in a straight line at a constant speed, unless it is compelled to change that state by forces acting on it
Newton's second law
The acceleration produced by the net force on an object is directly proportional to the magnitude of the net force, in the same direction as the net force, and is inversely proportional to the mass of the object (a= F/m)
when the air resistance on an object equals the weight of that object in terms of direction
Newton's third law
whenever one object exerts a force on a second object, the second object exerts an equal and opposite force on the first object
law of conservation of momentum
in the absence of an external force, the momentum of a system remains the same
law of conservation of energy
energy cannot be created or destroyed, it can only be transformed from on form into another, but the total amount of energy never changes
law of universal gravitation
Newton's law that states that all objects in the universe attract each other by the force of gravity
universal gravitational constant, G
the constant G in the equation for Newton's law of universal gravitation; measures the strength of gravity
fundamental electrical property explaining the mutual attractions or repulsions between electrons or protons.
conservation of charge
the law that states that charges are neither created nor destroyed but only transferred from one material to another
F=kq1q2/dsquared, The force between two charges particles is inversely proportional to the square of the distance between them.
when one side of an atom or molecule is induced to be slightly more positive or negative
when charge is redistributed on an object because of the presence of a charged object nearby.
the rate at which electrical energy is converted to into another form such as, mechanical energy, heat, or light
when electrical devices are connected to form branches with multiple paths for the electrons to flow
when electrical devices are connected in a single pathway with one path for the electrons to flow
the ends of a magnet where the magnetism is concentrated, they produce magnetic forces (like forces repel, and opposite forces attract)
The phenomenon of inducing voltage voltage by changing the magnetic field around a conductor
The induced voltage in a coil is proportional to the product of the number of loops and the rate at which the magnetic field changes within those loops.
