| Question | Answer |
|---|---|
| Momentum | The product of an objects mass and it's velocity |
| Formula for momentum | M=pv |
| Law of conservation of momentum | The total momentum of any group of objects remains the same unless outside forces also act on the objects |
| Force | A push or a pull that gives energy to an object |
| Units of force | Forces are measured in newtons;N |
| Net force | The total or all the forces acting on an object |
| Inertia | The tendency of matter to resist a change in it's motion |
| Balanced forces | The net force acting on an object is zero |
| Unbalanced forces | The net force acting on an object is not zero |
| Magnitude | The amount in size of measurement |
| Friction | A force that one Surface exerts on another when the two surfaces are in contact with each other |
| Static friction | Friction between non moving objects |
| Kinetic friction | Friction between moving objects |
| Sliding friction | Friction between objects that slide |
| Rolling friction | Occurs when an object rolls over a surface |
| Fluid friction | Occurs when an object moves through a fluid or a gas |
| Newtons first law of motion | Objects at rest will stay at rest & objects in motion will stay in motion at a constant velocity unless acted on by an unbalanced force |
| Newtons second law of motion | The net force acting on an object is equal to the product of the objects mass and acceleration |
| Newtowns third law of motion | For every action force there is a reaction force that is equal, but acts in the opposite direction |
| Law of universal gravitation | All objects in the universe are attracted to each other; strength of attraction depends on the objects masses and distances from each other |
| Freefall | The motion of an object when gravity is the only force acting on it |
| Terminal velocity | Greatest velocity of a falling object; occurs when the force of gravity is equal to the force of friction |
| Weight | A measure of a force of gravity on an object |
| Mass | The amount of matter in something |
| Centripetal force | The force that is pulling an object in circular motion towards the center of the circle |
| Geosynchronous orbit | Occurs when an object orbits another object and at a rate equal to the 2nd objects rate of rotation |
