Different graphs for motion include speed increasing, decreasing, constant, and stationary, with corresponding graphs for acceleration increasing, decreasing, deceleration increasing, and decreasing. Terminal velocity is reached when speed and air resistance balance out, with weight equaling air resistance.
Insights
- The concept of terminal velocity occurs when speed and air resistance reach equilibrium, where weight equals air resistance. Momentum is defined as mass multiplied by velocity, with the direction determining whether momentum is positive or negative. The principle of momentum asserts that the total momentum before a collision equals the total momentum after, with impulse calculated as force multiplied by the time taken.
- Pressure in liquids rises with depth, determined by density, gravity, and height. Boyle's Law establishes an inverse relationship between pressure and volume, while temperature increments lead to higher pressure due to heightened kinetic energy and collisions. Various topics like refraction, diffraction, thermal physics, thermometer properties, heat transfer, light properties, magnetism, and atomic physics are also covered.
