Forces
Non contact forces
What is forces that exert force without touching the object?
What do magnetic forces depend on
size of magnetic force and distance
what does electric force depend on?
Size and distance
what two things does gravitational force depend on?
What is weight and Mass?
Three types of non contact forces
What is Electrical,gravitational,and magnetic forces?
What is an example of the greatest magnetic force we have on earth?
North/South magnetic poles
Example of static electricity
static electricity can be explained in a balloon, When a balloon is rubbed the friction between the balloon and what is rubbing it cause static electricity?
Difference in Mass and weight
What is weight is measure of gravity and mass is the amount of atoms in an object?
where are forces found?
everywhere
How can you increase the Amount of Magnetic Force in objects?
Bigger magnets and closer range.
how can we increase electric forces
To increase the amount of electric force you can make the magnitude of the charges bigger or pull both object closer together so there's less distance.
what is objects with more mass and less distance?
two different types of forces
Non contact and Contact
Difference between the Geographical North and south and the Magnetic North and South
They are opposites
What is an electromagnet?
using an electrical current to magnetize sides of a piece of metal causing it to become magnetic
How to leave gravitational pull
More force going out than gravity is pulling you in
objects moving without touch
What is Non Contact forces?
evidence that a magentic force exist
Compass needles align with poles
How would an electron interact with a proton? Think about the charges they have
Attract
why does our moon orbit us but the sun is so much larger?
The moon is really close to us
