Question

How do we find the velocity, displacement, and acceleration from given values?

Answer 1

To find velocity, displacement, and acceleration from given values, you can use the following equations and principles:

1. Velocity:

   • Velocity is the rate of change of displacement over time.
   • If you have the initial velocity (u), the acceleration (a), and the time (t), you can calculate the final velocity (v) using the equation: v = u + at

2. Displacement:

   • Displacement is the change in position of an object.
   • If you have the initial displacement (s0), the initial velocity (u), the acceleration (a), and the time (t), you can calculate the displacement (s) using the equation: s = s0 + ut + 0.5at² (This equation assumes constant acceleration.)

3. Acceleration:

   • Acceleration is the rate of change of velocity over time.
   • If you have the initial velocity (u), the final velocity (v), and the time (t), you can calculate the acceleration (a) using the equation: a = (v - u) / t

These equations can be used to find the velocity, displacement, and acceleration of an object under different conditions. It's important to note that these equations assume constant acceleration. If the acceleration is not constant, more complex equations or numerical methods may be required.
