- 20. A man is driving a car on a road at a decently high velocity. He notices a stop sign immediately in front of him and slams the brakes. His body almost flies forward when he stops, only saved by his seat belt. What law in physics explains why the man's body jolted forward in this situation?
- 22. An object with a non-zero weight is suspended in the air by a rope. What type of force is the rope undergoing?
- 23. Steven pushes against a car with a force of 70N. The car pushes back against Steven with a force of 70N. What concept in physics would explain why this happens?

- 1. Jimmy, Alan, and Jason are playing tug of war. Jimmy and Alan are pulling the rope away from Jason who is pulling the rope away from them. Jason is pulling with a force of 123N, Alan is pulling with a force of 84N, and Jimmy is pulling with a force of 98N. What might a force of 54N represent in this situation?
- 2. The force of attraction between all bodies with mass in the universe.
- 3. In our solar system, planets stay in orbit around our sun due to gravity. However, what is the force that causes to the planets to rotate around the sun?
- 6. Planet X with a mass of 'a' is orbiting around a star with a mass of 'b'. If 'a' and 'b' are given and planet X's center is about 2AU away from it's star's center, then what number would be needed to calculate the force of gravity between planet X and it's star?
- 7. The following is a representation of a ____.
- 8. One ____ is defined as the force required to provide a mass of one kilogram with an acceleration of one meter per second squared.
- 10. A book is resting on a table and the force of gravity is attempting to pull it downward. What other force is acting on the book?
- 12. A box with a non-zero mass is pushed horizontally across a horizontal surface at a constant speed. The push force applied is equal in magnitude to the ____ ____ between the box and the surface.
- 15. A surfer on a surf board paddles toward a wave at a non-zero velocity. A wave churns up an hits the board in the opposite direction. After the board is the struck, the surfer remains on the board. What concept in physics would cause the surfer to stay on the board?
- 17. The 4th grade class of an elementary school is divided up to play a game of tug of war with half the kids on one end and the other half of the children on the opposite end. Both groups pull their hardest with equal force causing the rope to remain stationary. According to the situation what can be said about the forces?
- 21. The force that opposes motion when two surfaces are tangent to each other.
- 24. A skydiver jumps off an airplane high above the Earth. He initially accelerates, but after a period of time this acceleration is discontinued long before contacting the Earth. What is the reason for his acceleration to stop?
