"An object at rest remains at rest, and an object in
motion remains in motion at constant speed and in a
straight line unless acted on by an unbalanced force."

Newton's first law states that when an object that is unmoving stays unmoving and an object that is moving moves in a straight line and at a constant speed unless a different force that isn't balanced affects it. Basically a object should move in a straight line at a constant speed unless it's it changed by an unbalanced force.  This law sometimes is also called the law of inertia

Force is the push and pull on an object which changes the motion of the object; forces have a size and direction.
This was seen in the "Hoop and marker" activity when the person pushed the hoop causing the marker to fall into the jar. The force in this activity was the push acted upon the object and gravity causing it fall.

When an object is at rest that means that the object is in it's resting position or isn't moving.
This was seen in the "Hoop and marker" activity when the marker was on top of the hoop and there was no change in velocity and speed causing the marker to not move from it's resting position. This means that the object was at rest on top of the hoop.

When an object is in motion that means that the object is moving and there is a change in speed and velocity from when it was in the resting position.
This was seen in the "Hoop and marker" activity when the marker fell from on top of the hoop and into the jar. This means that the object moved from it's resting position because of the change in speed and velocity which caused the object to be in motion.

An unbalanced force is when all the forces on the object add or subtract to more than 0N. This means that the object is moving.
This was seen in the "Hoop and marker activity" when the marker started moving from it's place on top of the hoop and into the jar. This happened because the 2 forces(the push from the person and gravity) were unbalanced. The forces were unbalanced because they were both being pushed in the same direction which is towards the ground causing the 2 forces to unbalanced.

Inertia is when an object that isn't motion resists and continues to not move, and if the object is motion it will resist change in speed and velocity until an outside force acts on the object causing speed and velocity to change.
This was seen in the "Hoop and marker" activity when the marker had gone from it's resting position on top of the hoop to being inside the jar. The velocity and speed had changed because an outside force (the person pushing the hoop) had caused the marker to fall. If an outside force wasn't there the marker and hoop would have resisted change and stayed in the resting position.

A balanced force is when all the forces on the object add or subtract to 0N.
This was seen in the "Hoop and marker" activity when the forces coming from left and right equaled each other out causing it to be balanced. If they weren't balanced then the marker would have missed the jar by a couple inches on te left or right. Therefore the 2 forces coming form the left and right were balanced causing the marker to fall successfully into the jar.

Define and explain where seen in activity
Mass is all the energy or force in an object.
The mass in the "Hoop and marker" was the all the forces on the on the hoop and marker added together. In this case all the added forces on the hoop and marker resulted in the change of speed and velocity causing the hoop and marker to fall downwards. This shows when all the forces were added causing the mass to be heavier downwards.
