forces
1. Magnet attracting an object
Non-contact force
6 Noncontact attractive force that exists between all objects that have mass
Gravity
11. Besides gravity there are other noncontact forces....
electricity and magnetism
14.what happens when two north pole magnets are brought together
the magnets repel
19. If 2 magnets repel each other what poles are facing each other?
what is north south or south north
2. truck pulling a car
contact force
7. gravity is dependent on
Mass and distance
12 Mass is
the amount of matter in something
15. The entire region surrounding a magnet is known as the:
magnetic field
3. pushes or pulls that results from two objects touching each other
contact force
8.Gravity is a force that works at a distance like
electric fields and magnetic fields
13. Weight is
the the gravitational pull on an object
16. if 2 magnets attract what poles are facing each other?
north south
4. Gravity pulling us down to earth
Non-contact force
9. the direction gravity exerts its force on objects
pulls objects toward objects
17. what is the affect of decreasing distance on electromagnet force?
The smaller the distance between two electromagnets, the greater the force.
20. what is required for a magnet to create an electromagnetic force
a flowing current
5.Force that pull our hair toward a balloon
Electrostatic force or static electricity
10 mass and distance affect gravity by
increasing the force of gravity if mass isincreased and distance is decreased, decreasing the force of gravity if mass is decreased or distance is increased
18. The table above shows information about pairs of charged spheres. In which pair do the spheres exert the greatest electrical force on each other?
The spheres in Pair Y exert the greatest electrical force on each other compared to the other pairs of charged spheres in the data table, due to the greater charge and the smaller distance
