| Term | Definition |
|---|---|
| What is the size of an atom? | -15 1 X 10 M |
| What is the diameter of an atom? | -10 1 X 10 M |
| Density (Formula) | Mass Volume |
| Density is | Mass per unit Volume |
| Density of a... | Substance varies with sate but Mass doesn't |
| Specific Heat Capacity (formula) | Change in Thermal Specific Heat Change in = Mass(kg) X Capacity (J/kgC) X Temp Energy (J) |
| You need to Put in Energy to.... | Break Inter-molecular Bonds |
| Specific Latent Heat is.... | Energy needed to Change State |
| Specific Latent Heat (Formula) | Thermal Energy Specific Latent = Mass(kg) X Heat (J/kgC) for a Change in State |
| Colliding Gas particles... | Creates Pressure |
| Change in Temperature..... | Changes the Pressure |
| Speed, Distance & Time (Formula) | Distance = Speed (m/s) X Time (s) |
| Acceleration (Formula) | 2 Change in Velocity(m/s) Acceleration(m/s ) = Time (s) |
| Acceleration is.... | Rate of change of Velocity |
| Uniform Acceleration (Formula) | (final velocity2) - (initial velocity)2 = 2 X acceleration X distance (m/s)2 (m/s)2 (m/s2) (m) |
| Distance Time Graphs..... | Tell you how far something has travelled |
| Velocity Time Graphs... | Used to find Acceleration |
| Forces can be.. | Contact or non-Contact |
| Resultant Force... | Overall force on a point or object |
| Free Body Force Diagrams show... | All the Forces Acting on the Body |
| A Resultant Force of 0 mean.. | All the Forces are Balanced |
| A non-0 Resultant Force means... | The Forces are Unbalanced |
| Equilibrium | All the Forces on it are Balanced |
| Newton's First Law says.. | An object will remain stationary or at a constant velocity unless acted upon by an external force |
| Newton's Second Law say... | The force acting on an object is equal to its rate of change of momentum |
| Force (Formula) | Mass (KG) X Acceleration (m/s2) |
