Force Basics
This type of force can act at a distance with no direct physical contact required
What is a non-contact force?
The strength of the gravitational force between two objects is dependent on these values.
What is mass and distance?
The area around a magnet where its magnetism can affect other materials.
What is a magnetic field?
The two types of charges involved in electrostatic force.
What is positive and negative?
This is Mrs. Cook's favorite animal.
What is cats?
These are the three main types of non-contact forces.
What is gravitational, electrostatic, and magnetic?
As the masses of two objects increase, the gravitational force between them _________.
What is increases?
The magnetic field of this object is responsible for technology such as a compass.
What is Earth?
If a charged particle has a larger charge, this would create a _________ electrostatic field.
What is stronger?
This can be done to increase the strength of the magnetic field surrounding an electromagnet.
What is increase the coils OR increase the current?
This force is only an attractive force and never repels.
What is gravitational force?
Defined as the force exerted on a mass by gravity. This value would change if you went from Earth to the Moon.
What is weight?
This type of reaction occurs when two north poles of a magnet are brought together.
What is repulsion?
This type of reaction occurs when two positive or two negative charges interact with each other.
What is repulsion?
This is Mrs. Cook's favorite candy.
What is Nerds Clusters?
Within a field model, closer lines represent that the field is ____________ at that region.
What is stronger?
Planetary orbits relay on the gravitational force provided by this massive celestial body.
What is the Sun?
The magnetic field surrounding a magnet is strongest at _________.
What is the poles?
If a particle has a net negative charge, it has more of this type of subatomic particle.
What is electrons?
DAILY DOUBLE!! An iron needle has been given a positive charge. These fields will exert a force on the needle.
What is gravitational, electrical, and magnetic fields?
The unit of measurement for all forces.
What is Newtons (N)?
There is a gravitational force between all objects on Earth. However, many are not noticeable because their ______ is too small.
What is mass?
This type of magnet is generated by the flow of electric current through a wire, which creates a magnetic field.
What is an electromagnet?
If the distance between two charges increases, the strength of the force between them would ________.
What is decrease?
This is Mrs. Cook's favorite movie.
What is Mamma Mia?
