Gravity affects all objects with ________.
Mass
What is the shape of a magnetic field?
What is curved/oval shaped?
These two subatomic particles make up electric charges. (Particles: Protons (+), Neutrons (No charge), and Electrons (-)
Protons & Electrons
These fields can both attract and repel. (Fields we've learned: Gravitational, Magnetic, and Electric)
What is Magnetic & Electric fields?
What is Potential Energy
The energy stored in an object due to its position
The relationship between distance and gravitational force.
As distance increases, gravitational force decreases.
The interaction between like poles will _________
This subatomic particle is easier to give to other objects to generate static electricity.
What is Electrons?
These fields are known as "force at a distance".
What is Gravity, Magnetic, Electric?
To increase the PE of two objects you need to _____________.
Increase the distance
If you double the distance between two objects the gravitational force will decrease by what amount?
A factor of greater than 2
At what point on a magnet is the magnetic force the strongest?
At the poles
Attraction or Repulsion: The interaction between two opposite charges
What is Attraction?
T or F: Gravity is both an attractive and repulsive force.
What is False?
Moving two like charges (-, -) farther apart will result in what change of PE? (HINT: Think about their ability to attract to one another).
Decrease PE
What happens to gravitational potential energy as distance increases
GPE increases
What are two types of magnets?
What is permanent and temporary magnets?
The strength of an electric field increases as the distance _________.
Decreases
T or F: Static electricity is a force at a distance.
What is True?
What two factors influence Gravitational Potential Energy?
Mass & Distance (height)
These 2 things help increase the Gravitational potential energy of a cart on a ramp.
- Increase the mass
- Increase the height of the ramp
To INCREASE the magnetic field of an electromagnet (make it stronger), what is one thing you can do?
What is
- increase the voltage (electric current)
These objects can be affected by an electric field.
All objects
What is the "shock" named in static electricity?
What is Discharge?
