Newton's Laws Flashback
The law of motion that deals with force, mass, and acceleration.
What is Newton's 2nd law?
It is the area where a magnet exerts a force.
What is a magnetic field?
When you rub your hair on a balloon, it does this to water water. (attracts or repels)
What is attracts?
According to Newton's Universal Law of Gravitation, gravity is this. (Force, Mass, or Inertia)
What is force?
This CCC means 2 or more objects working together.
What is system?
The law of motion dealing with equal and opposite reactions.
What is Newton's 3rd law?
The positive and negative poles on a magnet are called this.
What are north and south?
If your sock sticks to your sweater when it comes out of the dryer, and it is determined that the sock has a net positive charge, the sweater must have this net charge.
What is negative?
T or F? As mass increases, gravity increases at a constant rate.
What is true?
This kind of scale would give you the same reading on the moon as it would on earth.
What is a balance scale? (i.e. triple beam balance)
The law of motion that deals with inertia.
What is Newton's 1st law?
The pole of a magnet that would be repelled by the north pole of a different magnet.
What is north?
This would happen when two negatively charged objects come near each other.
What is they would repel each other?
T or F? As distance increases, gravity decreases at a constant rate?
What is false?
This uses magnets and electricity to make motion.
What is an electric motor?
Any change in speed or direction.
What is acceleration?
This powerful magnet gains its strength by running electricity through a coiled wire around iron.
What is an electromagnet?
These are the particles you are rubbing off of atoms when you statically charge an object by rubbing it.
What are electrons?
This observation explains how the force of gravity changes by the square of the distance between two objects in a system.
What is the inverse square rule?
Different measures of size or time. (Hint: CCC)
What is scale?
This unit of force is defined as the amount of force needed to accelerate 1 kg at 1 m/s2.
What is a Newton?
It is a device that can create an electric current from motion using a magnet.
What is an electric generator?
This is what we call the force of attraction or repulsion between charged particles.
What is an electric charge?
The inverse square rule of gravity means that if an object were 3 times further from the earth, the force of gravity would be this many times weaker.
What is 9 times?
This theory from Albert Einstein changes how we view gravity compared to Newton's law of gravity.
What is relativity?
