|---|---|---|---|---|---|
| potential energy | The mechanical energy that a body has by virtue of its position; stored energy
🗑
|
||||
| kinetic energy | The mechanical energy that a body has by virtue of its motion
🗑
|
||||
| Law of Conservation of Energy | The fundamental principle of physics that the total energy of an isolated system is constant despite internal changes
🗑
|
||||
| radiant energy | Energy that is transmitted in the form of (electromagnetic) radiation; energy that exists in the absence of matter

🗑
|
||||
| sun | The source of all the energy on Earth
🗑
|
||||
| force | A dynamic influence that changes a body from a state of rest to one of motion or changes its rate of motion.
🗑
|
||||
| Balanced force | Object does not move or moves at a constant unchanging rate when forces are this
🗑
|
||||
| Unbalanced forces | Object changes its velocity when forces are this
🗑
|
||||
| Acceleration | A change in velocity or the speed and/or direction of an object
🗑
|
||||
| Inertia | the tendency of a body to maintain is state of rest or uniform motion unless acted upon by an external force. A property of matter
🗑
|
||||
| Net force | 1.the combination of all the forces that act on an object.
🗑
|
||||
| Speed | How fast something is moving
🗑
|
||||
| Velocity | How fast and in what direction an object is moving
🗑
|
||||
| Gravity | the force of attraction between all masses in the universe; especially the attraction of the earth's mass for bodies near its surface
🗑
|
||||
| Joule | Unit used to measure work
🗑
|
||||
| Work | the transfer of energy from one physical system to another expressed as the product of a force and the distance through which it moves a body in the direction of that force
🗑
|
||||
| Newtons | Unit used to measure force
🗑
