Physics 30 Unit 1
| Question | Answer |
|---|---|
| Mass*Velocity (mv) | Momentum |
| Mass*Acceleration (ma) | Force |
| ∆Velocity/∆Time (∆v/∆t) | Acceleration |
| Mass*Gravity (mg) | Weight |
| Force*∆Time (F*∆t) | Impulse |
| Mass*Gravity*Height (mgh) | Potential energy |
| 1/2mv^2 | Kinetic energy |
| Mass is measured in | Kilograms (kg) |
| Velocity is measured in | Metres per second (m/s) |
| Momentum is measured in | Kilogram metres per second (kg*m/s) |
| Acceleration is measured in | Metres per second per second (m/s^2) |
| Force is measured in | Newtons (N) |
| Energy is measured in | Joules (J) |
| Velocity is | The rate of change of an object's position |
| Force is | An influence on an object's motion |
| Momentum is | The product of the mass of an object and its velocity |
| Newton's first law | An object's velocity does not change without an external force |
| Newton's second law | The net force of an object is equal to the rate of change of its momentum |
| How is impulse found in a net force-time graph | By calculating the area under the graph |
| Elastic collisions are | Collisions where the objects in a system have the same initial and final kinetic energy values |
| Inelastic collisions | Collisions where the objects in a system have different initial and final kinetic energy values |
| Open systems are | Systems where outside forces act on the objects within |
| Closed systems are | Systems where outside forces can not act on the objects within |
| Impulse is | the product of the net force acting on an object during an interaction for a period of time |
