Force & Motion 2
| Question | Answer |
|---|---|
| Constant Speed | Constant speed means the speed does not change at all for each second of the motion. |
| Deceleration | the term used for acceleration that causes an object to slow down. |
| Gravitational force | a force that attracts any object with mass. |
| Inertia | a tendency to do nothing or to remain unchanged. |
| Newtons 1st Law Of Motion | state that an object at rest tends to stay at rest, with V=0m/s, and an object in motion tends to stay in motion with same speed and in the same direction unless acted upon by an unbalanced force. |
| Newtons 2nd Law Of Motion | The acceleration of an object as produced by a net force is directly proportional to the magnitude of the net force, in the same direction as the net force, and inversely proportional to the mass of the object. |
| Newtons 3rd Law Of Motion | The statement means that in every interaction, there is a pair of forces acting on the two interacting objects. The size of the forces on the first object equals the size of the force on the second object. |
| Relative Position | |
| Velocity | |
| Zero Net Force |
