When a force is unbalanced, that means that the Net Force is not 0 Newtons. As long as the force is not balanced, it is unbalanced.

In the Hoop and Marker activity, the marker fell into the jar from on top
of the hoop because of the unbalanced forces. There was the force of gravity pushing the marker down, although it lacked a force pushing or pulling it upwards at an equal force, therefore the force is unbalanced and caused the marker to fall into the jar.

If a force is balanced that means that an object's net force is 0 Newtons which means that two forces have canceled out each other and there is no change.

There is an example of Balanced force in the Hoop and Marker Activity. At the end of the activity, when the marker is in the jar, the Net Force of the marker would be 0N which would make the Net Force Balanced. Since there is an equal amount of Newtons pulling down on the marker and pulling the marker downwards, the two forces cancel out.

When an object is at rest, it remains that way and if an object is moving at a constant rate then it stays that way unless stopped or changed by an outside force.

Inertia is a measure of mass. With Inertia, an object will resist being moved the more Inertia it has. Although if the object is already in motion then Inertia will prevent there from being any change in direction or speed until there is an outside force applied.

In the Tablecloth Activity when the objects on the tablecloth had more inertia, they had a greater mass so they did not move when the cloth was pulled because they have a greater resistance than the objects with the lower inertia and mass. **Refer to Mass

If an object is at rest, then the object is unmoving. The Net Force of the object is 0 Newtons which means there is no change and there is a balanced force

There was balanced force in the Hoop and Marker activity because the hoop and the jar were all at rest until the hoop was moved.

When an object is in motion, the object continues to move until there is an outside force that stops or changes the movement.

An example of an object that was in motion during the Hoop and Marker activity was when the hoop was removed, the marker was in motion, being pulled down by gravity and would've continued to be pulled down if it wasn't for the outside force of the jar and table which stopped it.

An object's mass is the measure of the object's inertia. The mass of the object is greater the more the object resists change of speed or direction.

An example of mass would be in the Tablecloth Magic activity because when the tablecloth is pulled from underneath the objects, the objects with greater mass resisted change whereas the ones with less mass were affected more easily. **Refer to Inertia

A force is a push or a pull.
An example of force is in one of the activities is when the tablecloth was pulled from under the objects because a force (you) was pulling it.
