Crossword Puzzle on Momentum and Forces
Across
- 3. : The "m" in p = mv; a measure of inertia and NOT the same as weight
- 4. : Newton's First Law describes this property — the tendency of an object to resist changes in its state of motion
- 5. : Unlike speed, this quantity has both magnitude and direction; essential for calculating momentum
- 9. : Type of collision in which both momentum AND kinetic energy are conserved
- 10. : The law stating that total momentum in an isolated system remains constant before and after a collision
- 11. : Force multiplied by time; mathematically equals the change in momentum
- 13. : Momentum, velocity, and force are all this type of quantity — they have both magnitude AND direction
- 14. : An event in which two objects exert large forces on each other over a short time interval
- 15. : An _______ force is required to change
Down
- 1. : This force gives all objects near Earth a constant downward acceleration of approximately 9.8 m/s²
- 2. : The SI unit of force; one of these equals one kilogram times one meter per second squared
- 3. : The product of an object's mass and velocity; represented by the variable p
- 6. : Unit equal to one Newton-meter; used for both work and energy — also appears in impulse-energy problems
- 7. : When a gun fires a bullet forward, the gun moves backward due to this momentum conservation phenomenon
- 8. : Type of collision where kinetic energy is lost; objects may stick together
- 12. : A contact force that opposes motion and can reduce an object's momentum over time
