Understanding Particle Motion
When analyzing the motion of a particle moving along a straight line with increasing speed, it's essential to understand the relationship between velocity, acceleration, and speed changes.
Key Points to Consider
- Acceleration and Speed
- If a particle's speed is increasing, it implies that the acceleration must be in the same direction as the velocity. Therefore, the acceleration is positive.
- Negative Acceleration
- Negative acceleration occurs when the particle is slowing down. Since the particle in this scenario is speeding up, its acceleration cannot be negative.
- Decreasing Acceleration
- It's possible for acceleration to be positive yet decreasing in magnitude. For example, if a particle speeds up but does so less rapidly over time, it still has positive acceleration but is experiencing a decrease in acceleration.
- Conclusion
- The correct interpretation of the situation is that the particle has positive acceleration (option 3). It may also have a decreasing acceleration (option 2) if the rate of speed increase is lessening over time. Therefore, both options 2 and 3 can be true in this context.
Final Answer
The best choice in this scenario is option (4) both (2) and (3). The particle has positive acceleration, but that acceleration can be decreasing as it continues to gain speed at a slower rate.
