What is the formula for calculating acceleration?
What is the formula for calculating acceleration?
- $a = \frac{u + v}{t}$
- $a = \frac{v + u}{t}$
- $a = \frac{u - v}{t}$
- $a = \frac{v - u}{t}$ (correct)

Study Notes
Motion and Forces
- The formula for calculating acceleration is a = Δv / Δt, where a is acceleration, Δv is the change in velocity, and Δt is the time over which the change occurs.
- The unit of force in the International System of Units (SI) is the Newton (N).
- A vector quantity is a physical quantity with both magnitude and direction, and force is an example of a vector quantity.
