Newton's Laws
What is Newton's third law of motion?
For every action, there will be an equal and opposite reaction
What is K.E.?
Kinetic Energy is energy due to motion.
What are the two poles of a magnet?
North and South
What is Newton's Second Law of Motion?
The more mass an object has, the more force needed to accelerate it
What is P.E.?
Potential energy is energy stored in an object.
Which part of a magnet has the strongest attraction?
The poles
What is Newton's First Law of Motion?
An object at rest, will stay at rest unless acted upon by an unbalanced force. Same applies to an object in motion, an object in motion will stay in motion at a constant speed until it is acted upon by an unbalanced force.
Which has more Kinetic Energy:
A parked truck or a moving car
The moving car, because the truck is not moving so it has no K.E.
What would happen if you brought two South parts of a magnet together? would the attract or repel?
REPEL... if someone gets this wrong they are stupid
Friction is an example of which one of Newton's Laws of Motion?
Newton's First Law of Motion
Which will have more P.E.?
A pencil on the floor or a pencil on a table
The pencil on the table
If a magnet is spit in half, will there be two magnets with one pole each, or two magnets with two poles each?
Two magnets with two poles each
Which of Newton's Laws of Motion does the following demonstrate:
A shopping cart with many items in it is pushed, but it only travels a short distance. When an empty shopping cart is pushed it travels a larger distance.
Newton's Second Law of Motion
What is the difference between Kinetic Energy and Potential Energy?
Kinetic energy is energy due to motion, while potential energy is energy that is stored within an object.
What are the three Ferromagnetic Elements? What are their Symbols?
Iron (FE), Nickle (Ni) and Cobalt (Co)
