Newton's First law of motion can be defined as an object at rest will stay at rest and an object in motion will in a constant velocity unless it is acted upon by an unbalanced force. Newton's first law is also sometimes called the Law of Inertia.

Force in science is simply a push or a pull. This was seen in the activity Table Cloth Magic when the table cloth was pulled because the cloth was pulled by an unbalanced force.

Inertia is the tendency of all objects to resists any change in motion. This was
seen in the activity Table Cloth Magic when the objects stayed in place when the table cloth was pulled.

Mass is the measure of inertia. Large mass means large inertia, small mass means small inertia. This was seen in the activity Table Cloth Magic when the cloth was pulled and nothing moved. The Table Cloth Magic activity had a small inertia since the only the only thing that moved was the cloth.

When an object is in motion , it is moving. Objects will continue to move with the same velocity unless it is acted upon by an unbalanced force. This was seen in the activity Table Cloth Magic when the cloth was being pulled. Below is a picture of the task before the cloth was pulled.

When an object is at rest, it is not moving. An object at rest will stay at rest. This was seen in the activity Table Cloth Magic when the objects did not move after the cloth was pulled. Below is a picture of the task after the cloth was pulled.

Unbalanced forces or actions produce a change in motion. A change in motion can be seen in Table Cloth Magic when the cloth was at rest, but then was pulled. The cloth was at rest until the unbalanced force acted on the cloth.

Balanced actions or forces do not produce a change in motion. They do not cause non-moving objects to move. This was seen in the activity Table Cloth Magic when the objects on top of the cloth did not move despite the cloth being pulled.
