Energy
Kinetic, Potential, and Newton's 1st and 2nd Laws
Question | Answer |
---|---|
gravitational potential energy | energy stored due to position in a gravitational field; commonly due to Earth's gravity |
potential energy | energy that is stored |
kinetic energy | the energy an object has because of its motion; The kinetic energy of the object is dependent on the mass of the object as well as its velocity. |
chemical potential energy | amount of chemical energy stored in a substance |
elastic potential energy | potential energy associated with stretched or compressed objects such as springs or rubber bands. |
electrical potential energy | potential energy is related to the distance between charged particles as well as the strength of the electric charges. Two similarly charged particles will experience a very strong repulsive force when you move them close to one another. |
nuclear potential energy | potential energy is stored in the nucleus of an atom due to a force called the strong force |
unbalanced forces | push or pull on an object that is not subject to an equal and opposite push or pull |
force | a pull or push that is applied to an object |
work | a force applied to an object over a distance |
acceleration | a change in the velocity (speed, direction, or both) of a body ; The acceleration of an object is proportional to the force acting on the object, meaning that when the force increases, the acceleration increases. |
action force | movement; something that happens (related words: move, moving) |
reaction force | Forces occur in pairs. The first force is called the action force. The second force would be called: |
Newton's first Law | states that an object at rest stays at rest, and an object in motion remains in motion in the same direction and at the same speed unless an unbalanced force acts on it. |
Newton's second Law | describes, how quickly an object accelerates is directly related to the mass of the object and the magnitude of the force applied to it. |
gravity | a force that exists between any two objects that have mass |
balanced forces | when two equal forces are applied to an object in opposite directions, the object does not move |
Scientific Laws | a generalization or rule that describes recurring facts or events in nature |
Scientific Theories | a set of statements or principles devised to explain a group of facts or phenomena, especially one that has been repeatedly tested or is widely accepted and can be used to make predictions about natural phenomena. |
Newton's Laws | set of three rules describing the relationships between objects and their motion |
net force | the resulting force determined by combining all of the forces acting on an object |
friction | a force that opposes the motion of a body across a surface or through a gas or liquid |
inertia | an object's resistance to a change in motion; Newton's idea that improved on Aristotle's descriptions of motion |
velocity | the speed and direction of moving objects |
law of conservation of energy | which states that energy is never created or destroyed. Energy can only change from one form to another |
