Inertia is the tendency for an object to continue in a straight line motion at a constant speed unless acted upon by an unbalanced force (a force that can make a change). Inertia can also be an object staying at rest (speed = 0 m/s) unless an unbalanced force acts on the object.
When an unbalanced force acts on the tether ball, the ball can:

Isaac Newton found out that the strength of the pull of gravity weakens the farther you get away from an object, in proportion to y = 1/(r*r), where "y" is gravitational force and "r" is the distance you are away from the center or the radius. The strength of the gravitational pull is also proportional to the mass of the object.
Type the equation for gravity here on this graph. Tell your teacher what you noticed in this math relationship next time you see her.
