Gravity affects all objects with ________.
Mass
This will happen if you cut a magnet in half
Two magnets with north an south poles will be created
These two subatomic particles make up electric charges.
Protons & Electrons
These fields can both attract and repel.
Magnetic & Electric
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.
Electrons
These fields are known as non-contact forces
Gravity, Magnetic, Electric
To increase the Gravitational 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
The interaction between two opposite charges
Attraction
These can attract & repel
Magnetic & Electric
Moving two like charges farther apart will result in what change of PE?
Decrease PE
What happens to gravitational potential energy as distance increases
GPE increases
A magnet
The strength of an electric field increases as the distance _________.
Decreases
This field is only attractive
Gravitational
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
- Raise/Increase the release height
To INCREASE the magnetic field of an electromagnet (make it stronger), these are the 2 things you can do.
What is
- increase the voltage (electric current)
- increase the coil density
These objects can be affected by an electric field.
All objects
This can affect all objects
Gravity & Electric Fields
How can you increase the Magnetic Potential Energy of:
- 2 magnets with the same poles facing each other?
- 2 magnets with opposite poles facing each other?
Magnetic Potential Energy increases for
- 2 magnets with same poles facing when you move them closer
- 2 magnets with opposite poles facing when you move them further away from each other
