What is the formula for acceleration?
What is the formula for acceleration?
- Acceleration = s / t
- Acceleration = (v - u) / t (correct)
- Acceleration = (v + u) / t
- Acceleration = u + at
The formula for final velocity can be expressed as v = u + at.
The formula for final velocity can be expressed as v = u + at.
True (A)

Speed
Speed
The rate at which an object moves, calculated by dividing the distance traveled by the time taken.
Velocity
Velocity
Speed with a direction. It tells us how fast an object is moving and in what direction.
Acceleration
Acceleration
The rate of change of velocity over time. A positive value means speeding up, a negative value means slowing down.

Linear Motion Formulas
- Speed: Distance / Time
- Velocity: Distance / Time
- Average Velocity: (u + v) / 2 or s / t
- Acceleration: (v - u) / t
- Final Velocity (v): u + at
- Displacement (s): ut + 1/2at²
- Final Velocity² (v²): u² + 2as
- Slope (m): (y₂ - y₁) / (x₂ - x₁)
