Kinetic/Potential general knowledge practice for application quiz (Ms. Cox)
Terms in this set (13)
What is kinetic energy?
the energy of moving things
What are some examples of kinetic energy?
rolling ball, swinging rope, vibrating spring
What are some examples of kinetic energy being transformed into potential energy?
object moves uphill, elastic object stretches, pendulum swings to its highest point
What is the relationship between net force applied, mass, and change in object motion?
Net force is applied to an object that has mass, the object accelerates in the direction of the net force. If forces are balanced then no acceleration.
What is potential energy?
energy an object has due to its position or chemical composition
What are some examples of potential energy?
resting book, stretched rubber band, battery
What are the two types of potential energy?
gravitational and chemical
How does potential energy turn into kinetic energy?
motion: an object's ability to "react" takes place
What is the law of conservation of energy?
energy is neither created nor destroyed
How is energy transferred in a simple system?
Energy moves from one object or place to another
What are some examples of an energy transfer?
chemical energy in flashlight battery becomes light
How does the law of conservation of energy apply to kinetic and potential energy?
The energy of motion and non motion in a situation remain equal before and after an interaction takes place
Why is energy conserved as it transfers between objects?
Energy can not be created or destroyed-only changes its form.
