425 years
How does the mass of an object affect gravity?
Objects with greater mass use more gravity
What is it called when no movement and no work occur when both forces are equal?
Balanced Force
What is used to measure force/gravity?
Newton
What is an unbalanced force?
Work being done and a change in motion takes place

Name the three non-contact forces
Magnetic, Electrostatic/Electrical and Gravitational
Name three objects that would be attracted to a magnet
Materials made from iron, steel, metal ( coins, needles, staples etc)
Name three of the contact forces
Frictional Force, Applied Force, Normal Force, Tension Force, Air Resistance, Spring Force
If you had one magnet marked north and south and one magnet unmarked, how would you find out which is the north/south pole of the unmarked magnet?
By placing them beside each other, if the magnets attract to each other that means opposite sides are facing each other.
