Gravity pulls the moon to the earth stronger than the sun because
the earth is closer
objects with a greater mass have
a greater force
Like charges do what with each other
repel
A force between two objects that are far apart are
weak
A strong charge means that the force is
strong
Gravity between the sun and what keep them in orbit
planets
objects whose masses are small have
a weaker force
A charge that creates electrical field is called what
electrical charge
An object with a greater mass has what kind of force
stronger
A weak charge means that the force is
weak
the same force that causes an apple to fall from a tree is the same force that
causes the moon to move around the earth
