Electricity and Magnetism
What types of charges do atoms have?
Neutrons,Protons,Electrons
What makes up an element?
a substance made up of one kind of atom
Whats the definition of force?
a push or a pull
What is the definition of mass?
the amount of matter in something
Whats is the definition of Static Electricity?
a stationary electric charge, typically produced by friction, which causes sparks or crackling or the attraction of dust or hair.
What main 2 types of circuits are there?
Series and parallel circuits
What is the negative charge called in the element?
Electron
Which of the following is a force?
A. inertia B. friction
C. acceleration D. velocity
A. inertia
According to Newton's second law of motion force is equal to mass times?
A. inertia C.direction
B.weight D. acceleration
d. acceleration
Parallel Circuit
A parallel circuit is a closed circuit in which the current divides into two or more paths before recombining to complete the circuit. Each load connected in a separate path receives the full circuit voltage, and the total circuit current is equal to the sum of the individual branch currents.
Give some examples of conductors
Conductors- metal, water
What is the number called in the corner of the elements on the periodic table?
Atomic number
When an unbalanced force acts on an object, the force ( what does the force do) H.I.N.T it changes something
It changes it's motion of the object
The equation that represents Newton's second law of motion is?
F=m x a
Resistance
the refusal to accept or comply with something; the attempt to prevent something by action or argument.
What is a motor?
A device that changes electrical energy into mechanical energy that can do work.
How many elements are there?
118
A 10N force pull on an object to the right and a 36N force pulls the the left, what is the net force(+direction) on the object?
26N to the left
How do you find mass of an object?
Amps
short for ampere.
If a north end and a north end are pointing towards each other what will happen?
The two magnets will repel because they are the same magnetic forces.
What is the most shown element on the periodic table?
transition metal
The mass of the moon is nearly 10% of the mass of the earth. What will be the gravitational force of the earth on the moon, in comparison to the gravitational force of the moon on the earth?
a) Both of the force will be equal
b) Gravitational force of the earth on the moon is much lesser
c) Gravitational force of the moon on the earth is much lesser
d) There is no effect
Answer is A
Ohms
ohms (symbol Ω) usually refers to the plural for the unit of electrical resistance, named after Georg Ohm.Ohms or OHMS may also refer to: Ohm's law of electric currents, first proposed by Georg Ohm.O.H.M.S., On His/Her Majesty's Service. O.H.M.S.
