| Acceleration = |
The rate at which velocity is changing. |
| Action Force = |
One of the pairs of forces described in Newton's 3rd Law of motion. |
| Force = |
Any influence that tends to accelerate an object. |
| Interaction = |
A mutual action between objects where each object exerts an equal and opposite force on the other. |
| Law = |
A general hypothesis or statement about the relationship of natural quantities that has been tested over and over again and has not been contradicted. |
| Newton's 3rd Law = |
Whenever one body exerts a force on a second body, the second body exerts and equal and opposite force on the first body. |
| Mass = |
A measure of an objects inertia and the measure of the amount of matter in an object.
|
| Motion = |
The act of an acceleration on an object. |
| Reaction Force = |
The force that is equal in strength and oppsiste in direction to the action force |
| Velocity = |
Speed together with the direction of motion.
|
| Weight = |
The force on a body due to the gravitational attraction of another body. |
