Law of Motion
The force that opposes the motion of an object as it slides over a surface
What is Friction?
This type of mechanical energy is associated with the motion of an object
What is kinetic energy?
The force that's responsible for the attraction or repulsion between objects that have magnetic properties
What is magnetism?
Positively charged particles
What are protons?
An object at rest will stay at rest, and an object in motion will stay in motion unless acted upon by an external force
What is Newton's First Law of Motion?
This type of mechanical energy is stored in an object due to its position or configuration
What is potential energy?
These two types of magnetic poles always come in pairs, and like poles repel each other while opposite poles attract.
What are North and South poles?
Materials that allow electricity to flow through them easily, while these other materials do not
What are conductors and insulators?
This principle states that for every action, there is an equal and opposite reaction.
What is Newton's Third Law Of Motion?
This type of potential energy depends on an object’s height and the force of gravity acting on it
What is gravitational potential energy?
Ferro magnetic materials
What are iron, nickel, and cobalt?
What causes objects to either attract or repel each other through electric force
What is an electric charge?
The equation F = ma
What is Newton's Second Law Of Motion?
Why a roller coaster at the top of a hill has maximum potential energy and maximum kinetic energy at the bottom
What is energy transformation?
Magnets that do not lose their magnetic properties over time, unlike temporary magnets.
What are permanent magnets?
This invisible field surrounds a charged object and exerts a force on other charged objects in the area
What is an electric field?
The resistance of an object to change its state of motion
What is inertia?
This formula calculates the kinetic energy of an object, depending on its mass and velocity (m - mass, v - velocity)
What is 1/2 mv²?
Occurs when an electric current is passed through a wire, creating a magnetic field around the wire.
