1. What is the SUVAT Equation?

The SUVAT equations are a set of kinematic equations that describe the motion of objects under constant acceleration. The equation v = u + at calculates final velocity (v) from initial velocity (u), acceleration (a), and time (t).

2. How Does the Calculator Work?

The calculator uses the SUVAT equation:

Where:

• \( v \) — Final velocity (m/s)
• \( u \) — Initial velocity (m/s)
• \( a \) — Acceleration (m/s²)
• \( t \) — Time (seconds)

Explanation: This equation calculates the final velocity of an object after it has undergone constant acceleration for a certain time period.

3. Importance of SUVAT Calculations

Details: These calculations are fundamental in physics for solving problems related to motion, including projectile motion, vehicle acceleration, and free-fall scenarios.

4. Using the Calculator

Tips: Enter any three known values to calculate the fourth. All values should be in SI units (meters and seconds). Time must be positive.

5. Frequently Asked Questions (FAQ)

Q1: What does SUVAT stand for?
A: SUVAT is an acronym from the variables: Displacement (s), Initial velocity (u), Final velocity (v), Acceleration (a), and Time (t).

Q2: When can SUVAT equations be used?
A: Only when acceleration is constant. They don't apply to situations with changing acceleration.

Q3: What are typical units for SUVAT calculations?
A: Standard SI units: meters (m) for distance, seconds (s) for time, and meters per second squared (m/s²) for acceleration.

Q4: How is this equation derived?
A: It comes from the definition of acceleration as the rate of change of velocity with respect to time (a = (v-u)/t), rearranged to solve for v.

Q5: Can this be used for deceleration?
A: Yes, deceleration is just negative acceleration. Enter a negative value for 'a' when slowing down.
