Its changed because we now have more technology than 50 years ago or more. We now have far more advance technology and we can see the particles and more information which is more accurate

When does distance travelled by a particle is proportional to time?

The distance travelled by a particle is proportional to time when the particle moves with a constant velocity. This means that for every unit of time that passes, the particle covers a consistent amount of distance.


A particle is moving along the x-axis. The line graph shows the velocity of the particle over time. When is the instantaneous acceleration of the particle equal to 0?

The instantaneous acceleration of the particle is equal to 0 when the velocity of the particle is at a maximum or minimum. This occurs at the points on the graph where the slope of the velocity-time graph is horizontal or the velocity reaches a peak or trough.


How has ideas on particles changed over time?

Over time, the understanding of particles has evolved from ancient Greek concepts of indivisible atoms to the modern standard model, which describes particles as fundamental building blocks of matter. The development of quantum mechanics in the 20th century revealed the wave-particle duality of particles, challenging earlier notions of classical physics. Advancements in experimental techniques, such as particle accelerators, have allowed for the discovery of new particles and the confirmation of theoretical predictions.


Has the speed of light changed over time?

No, the speed of light has remained constant over time according to current scientific understanding.


Can particle with velocity or speed at zero be accelerating?

Yes, a particle can have a velocity of zero and still be accelerating if its speed is changing. Acceleration is the rate at which the velocity of an object changes over time, so even if the particle's velocity is momentarily zero, if it is changing, it is experiencing acceleration.
