200
The property of a spring, designated by the symbol k, that measures its stiffness.
Spring Constant
200
The term for the motion of an object falling without the influence of any other force, such as air resistance.
Free Fall
200
The classification given to processes like weathering, erosion, earthquakes, and landslides because they wear down or destroy landforms.
Destructive forces
300
What motion is shown on a velocity versus time graph when the line is in the negative quadrant and moving further away from the horizontal axis?
Moving left and speeding up
