| 16310187634 | acceleration | increase in the rate or speed of something. |  | 0 |
| 16310187635 | acceleration due to gravity | If gravity is the only force acting on an object, then we find the object will accelerate at a rate of 9.8m/s2 down toward the center of the Earth (this is often rounded to 10m/s2). |  | 1 |
| 16310187636 | air resistance | air resistance, a type of friction, or fluid resistance, another type of friction or fluid |  | 2 |
| 16310187637 | distance | an amount of space between two things or people. |  | 3 |
| 16310187638 | force | strength or energy as an attribute of physical action or movemen |  | 4 |
| 16310187639 | gravity | the force that attracts a body toward the center of the earth, or toward any other physical body having mass. |  | 5 |
| 16310187640 | gravitation potential energy | Gravitational potential energy is energy an object possesses because of its position in a gravitational field. |  | 6 |
| 16310187641 | inverse-square relationship | inverse square of the distance between the object and the source of the force. The magnitude of light, sound, and gravity obey this law, as do other quantities. |  | 7 |
| 16310187642 | kinetic energy | energy that a body possesses by virtue of being in motion. |  | 8 |
| 16310187643 | mass | a coherent, typically large body of matter with no definite shape. |  | 9 |
| 16310187644 | Newton's Law of Universal | Newton's law of universal gravitation states that a particle attracts every other particle in the universe using a force that is directly proportional to the product of their masses and inversely proportional to the square of the distance between them. Newton's law of universal gravitati |  | 10 |
| 16310187645 | Gravitation | movement, or a tendency to move, toward a center of attractive force, as in the falling of bodies to the earth. |  | 11 |
| 16310187646 | normal force | normal force F n {\displaystyle F_{n}\ } is the component, perpendicular to the surface (surface being a plane) |  | 12 |
| 16310187647 | Orbit | the curved path of a celestial object or spacecraft around a star, planet, or moon, especially a periodic elliptical revolution. |  | 13 |
| 16310187648 | potential energy | the energy possessed by a body by virtue of its position relative to others, stresses within itself, electric charge, and other factors. |  | 14 |
| 16310187649 | weigth | A measure of the force of gravity on an object |  | 15 |
