Constant Acceleration
When a particle experiences constant acceleration, its velocity changes by the same amount in equal intervals of time. This means that the velocity-time graph will be a straight line.
Distance Traveled
To determine the relationship between the distances traveled in the first 10 seconds (S1) and the next 10 seconds (S2), we need to consider the equations of motion.
The equation of motion that relates distance, initial velocity, time, and acceleration is:
S = ut + 0.5at^2
Where:
S = Distance traveled
u = Initial velocity
t = Time
a = Acceleration
Since the particle is starting from rest, its initial velocity (u) is 0.
Calculating S1
For the first 10 seconds, we can use the equation of motion to calculate S1:
S1 = (0)(10) + 0.5a(10)^2
= 0 + 0.5a(100)
= 50a
Therefore, S1 is directly proportional to acceleration (a).
Calculating S2
For the next 10 seconds, the particle continues to experience the same constant acceleration. We can use the equation of motion again to calculate S2:
S2 = (0)(10) + 0.5a(10)^2
= 0 + 0.5a(100)
= 50a
Therefore, S2 is also directly proportional to acceleration (a).
Conclusion
From the calculations above, we can conclude that S1 and S2 are both directly proportional to the acceleration (a). This means that if the acceleration is doubled, both S1 and S2 will also be doubled.
In summary, the relationship between S1 and S2 is that they are both directly proportional to the acceleration.
