Why does an object in motion stay in motion unless acted on by an unbalanced force?
because forces are what stop and start motion
because balanced forces cannot exist in nature
because motion is the inherent state of all matter
because motion, once begun, continues to accelerate.

Race car drivers must slow down as they make turns on the track. This is best explained by the law of inertia. Which statement best describes inertia for the car going around a turn?
A body in motion stays in motion at the same speed.
The speed around a turn is proportional to the radius of curvature of the turn.
The speed of the car going into the turn must be conserved.
A body in motion tends to continue in a straight line and requires a force to turn.
The image above shows two opposite forces acting on a rope, what can we say is true about the effect of the forces on the rope?
It cannot be determined without knowing which man is stronger.
The forces are unbalanced, and net force on the rope moves it to the left.
It cannot be determined because one man is standing taller than the other.
The forces are unbalanced, and net force on the rope moves it to the right.

When pushing a child on a swing, you must give them a push periodically to keep them moving. This seems to go against the law of inertia and the conservation of energy. Explain why the child need a push periodically to keep moving.
Energy is lost over time slowing down the swing.
A wind must have been blowing in the opposite direction.
All objects will naturally come to rest over time.
Friction provides an outside force slowing the swing down.
Consider the data collected in science class. Different masses were thrown with varied amounts of force. The data table reflects Newton's 2nd Law of Motion, or F = ma. Based on the data collected, what conclusion can be stated about the objects acceleration?
In all cases, the acceleration was the same.
The acceleration increased as the force increased.
The acceleration decreased as the mass increased.
The greater the force, the greater the acceleration.
Consider the four diagrams. Do any of the free body diagrams indicate motion? If yes, which one(s). Explain.
No. In each case, the forces are balanced.
You cannot tell if there is any motion. You can only determine how much force is acting on the objects.
Yes. In B the book is slowing down because of the friction force opposing motion.
Yes. In B and D. In both cases, there is a net force. In B, there is a net force to the left; in D there is a net force upward.
