Contact or Non-Contact Forces
A foot kicking a soccer ball.
What is Applied Contact Force?
A force that can cause a change in motion through touch.
What are Contact Forces?
Force that happens when two objects DO NOT touch, but there is still a push or pull effect.
What are Non-Contact Forces?
The change brought on by objects interacting with each other.
What NORTH poles do when they are aligned with another NORTH pole.
What is Repel?
An apple falling off a tree.
What is Gravitational Non-Contact Force?
A typical force applied through push or pull.
What is Applied Force?
Materials like iron, nickel, cobalt and other magnets need to be near a magnet to be attracted or repelled.
Gravity can only affect objects with this.
What is mass?
What happens when you increase the distance between magnets.
What is decreases the strength of the magnets?
A compass needle turning North.
What is Magnetic Non-Contact Force?
Happens when two objects rub against each other. _______ OPPOSES motion.
What is Friction?
Force that only affects objects with a + or - charge.
What are Electric Forces?
Increasing mass does this to the strength of gravity.
What is increases?
What happens when SOUTH poles interact with NORTH poles of magnets.
What is attract?
Shoes rubbing against the floor.
What is Friction Contact Force?
“Support Force” that is exerted upon an object while it is in contact with another stable object.
What is Normal Force?
The force of attraction between any two objects in the universe.
What is Gravitational Force?
Increasing distance between objects does this to the strength of gravity.
What is decreases?
Materials that respond to magnetic fields.
What are nickel, cobalt, and iron?
A book sitting on a table.
What is Normal Contact Force AND Gravitational Force?
Type of frictional force that acts upon objects as they travel through the air.
What is fluid friction?
Gravitational Force is affected by two things... One is the STUFF a thing is made up of, and one is how FAR AWAY the object is.
What are Mass and Distance?
The ability an object has to stay at rest or continue in motion.
What is Inertia?
Aligning more of these strengthens magnets.
What are magnetic domains?
