Across
- 5. The number of cycles per unit of time
- 7. The time it takes for one complete cycle
- 9. law that states that force is equal to the spring constant multiplied by displacement (___ law)
- 12. A support force exerted on an object in contact with a stable surface, acting perpendicular to the surface the object it is resting on (___ force)
- 15. Found by calculating the area under a velocity time graph
- 16. A displacement time graph displaying a straight, horizontal line means that for the given time interval, the velocity of the object is:
- 17. second law For every action there is an equal and opposite reaction (three words)
- 18. Force applied over time, also the change in momentum over time
- 19. of momentum Total momentum before a collision is equal to the the final momentum after the collision
- 20. gravitational constant It has a value of 6.67 x 10 11 Nm2/kg2 and is denoted by “G” spring constant The “stiffness” of a spring, denoted by “k”
Down
- 1. Type of acceleration where an object is moving in uniform circular motion (___ acceleration)
- 2. An inward force acting on an object moving in a circular path (___ force)
- 3. A force that opposes the motion of an object as it moves across a surface
- 4. The force on an object that causes a displacement, measured in joules
- 6. Type of force required to return a spring to its original position (___ force)
- 8. During this type of collision, kinetic energy is lost
- 10. The minimum velocity required for an object (starting from the surface of a planet) to escape the potential well of said planet (___ velocity)
- 11. Mass in motion, measured in kg*m/s
- 13. direction and magnitude
- 14. velocity the point where a falling object has no acceleration (two words)
