Forces
Non contact forces
What is forces that exert force without touching the object?
what is a contact force we've talk about
air resistance
What do magnetic forces depend on
what is the size of magnetic force and distance?
what does electric force depend on?
what is 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 air resistance
Air resistance is a force that is caused due to air when an object moves through it.
What are the three types of magnetic metals?
What is Iron,Nickel and, Cobalt?
how can we explain static electricty
What is 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?
What is Everywhere?
what is another word for air resistance
drag
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
What is Non contact and Contact?
Difference between the Geographical North and south an the Magnetic North and South
What is their opposites?
what does electric force look like
electrons attract protons
protons repel protons
electrons repel electrons
lines for a negative charge point towards
objects moving without touch
What is Non Contact forces?
evidence that a magentic force exist
Magnetized compass needles align with the earths magnetic field and tell us which direction is "North"
evidence force field exist
balloons attract or repel each other, lightning,electric shock from a door handle
