A steel ball is at one end of a box that is moving forward as shown. The box suddenly stops. According to Newton's first law, what happens to the steel ball just after the box stops?
Because of friction, the ball continues rolling forward at the same speed.
Because of friction, the ball rolls forward at an increased speed.
Because of inertia, the ball continues rolling forward at the same speed.
Because of inertia, the ball rolls forward at an increased speed.
When a coin is tossed in the air, it travels upward, gradually slows down, momentarily reaches zero speed, then moves back downward with increasing speed. Which statement best explains this change in the coin's motion?
The force of gravity causes the coin to change its velocity.
The coin's inertia decreases on the way up and increases on the way down.
The action-reaction force pair of gravity and the applied force cancel each other out.
The coin remains in its state of upward motion until the force of friction acts upon it.

The reason we have seasons on our planet is because...
we are closer to the sun during the winter and further during the winter.
the tilt of Earth's axis allows for more direct sunlight in the summer and less direct sunlight in the winter.
seasonal wind patterns carry warmer winds during the summer and colder winds during the winter.
the Earth's orbit becomes more like an oval to give us different seasons.
Which of the following best describes the tilt of the earth during the spring and fall equinoxes?
The earth is tilted away from the sun (Northern hemisphere)
