1. What is Average Speed?

Average speed is the total distance traveled divided by the total time taken. However, for constant acceleration, it can also be calculated as the arithmetic mean of initial and final velocities.

2. How Does the Calculator Work?

The calculator uses the average speed equation for constant acceleration:

Where:

• \( v_{avg} \) — Average speed (m/s)
• \( v_1 \) — Initial velocity (m/s)
• \( v_2 \) — Final velocity (m/s)

Explanation: This equation provides the average speed when acceleration is constant throughout the motion.

3. Importance of Average Speed Calculation

Details: Calculating average speed is fundamental in physics for analyzing motion, solving kinematics problems, and understanding the relationship between distance, time, and velocity.

4. Using the Calculator

Tips: Enter both initial and final velocities in meters per second (m/s). The calculator will compute the average speed.

5. Frequently Asked Questions (FAQ)

Q1: Is average speed the same as average velocity?
A: No, average speed is a scalar quantity (magnitude only), while average velocity is a vector quantity (magnitude and direction).

Q2: When is this equation valid?
A: This equation is valid only when acceleration is constant. For variable acceleration, other methods must be used.

Q3: What are typical units for speed?
A: While we use m/s here, other common units include km/h, mph, or ft/s depending on the context.

Q4: Can this be used for instantaneous speed?
A: No, this calculates average speed between two points in time. Instantaneous speed is the speed at a specific moment.

Q5: How does this relate to distance traveled?
A: Distance traveled can be calculated by multiplying average speed by time (d = v_avg × t).
