Describe initial and final velocity?
Initial and Final Velocity:
- What is Initial Velocity?
- What is Final Velocity?
- How to Calculate Initial and Final Velocity?
- Initial Velocity: It can be calculated by dividing the displacement by time and adding the acceleration multiplied by time. Mathematically, it can be represented as:
- Final Velocity: It can be calculated by adding the acceleration multiplied by time to the initial velocity. Mathematically, it can be represented as:
- Example:
- Initial Velocity (u) = 20 m/s
- Acceleration (a) = 4 m/s^2
- Time (t) = 5 s
- Final Velocity (v) = ?
- Using the formula:
- Substituting the values:
Initial velocity is the velocity at the beginning of the motion or the velocity with which an object starts moving.
Final velocity is the velocity at the end of the motion or the velocity with which an object stops moving.
Initial Velocity (u) = (Displacement (s) / Time (t)) - (Acceleration (a) * Time (t))
Final Velocity (v) = Initial Velocity (u) + (Acceleration (a) * Time (t))
Suppose a car is moving with an initial velocity of 20 m/s and accelerates continuously at 4 m/s^2 for 5 seconds. Find the final velocity of the car.
Final Velocity (v) = Initial Velocity (u) + (Acceleration (a) * Time (t))
Final Velocity (v) = 20 m/s + (4 m/s^2 * 5 s)
Final Velocity (v) = 40 m/s
