Velocity Analysis
Example Calculations
Car Velocity (Distance-Time)
Scenario: Car travels 500 meters in 3 minutes
Distance: 500 m
Time: 3 min = 180 s
Calculation: v = 500 m ÷ 180 s = 2.78 m/s
Result: 2.78 m/s ≈ 10 km/h ≈ 6.2 mph
Acceleration Example
Scenario: Car accelerates from 0 to final velocity
Initial velocity: 0 m/s (starting from rest)
Acceleration: 6.95 m/s²
Time: 4 seconds
Calculation: v = 0 + (6.95 × 4) = 27.8 m/s
Result: 27.8 m/s ≈ 100 km/h ≈ 62 mph
Average Velocity Example
Scenario: Object changes velocity over time
Initial velocity: 10 m/s
Final velocity: 30 m/s
Calculation: v_avg = (10 + 30) ÷ 2 = 20 m/s
Result: 20 m/s average velocity
Types of Velocity
Average Velocity
Total displacement ÷ total time
Vector quantity with direction
Instantaneous Velocity
Velocity at a specific moment
Derivative of position function
Terminal Velocity
Maximum velocity in free fall
When drag equals gravitational force
Physics Tips
Velocity is a vector quantity (has magnitude and direction)
Speed is scalar (magnitude only), velocity includes direction
Negative velocity indicates opposite direction
Constant velocity means zero acceleration
Units: m/s (SI), km/h, mph, ft/s
Understanding Velocity in Physics
What is Velocity?
Velocity is the rate of change of an object's position with respect to time. It's a vector quantity, meaning it has both magnitude (speed) and direction. Velocity tells us not only how fast an object is moving but also in which direction it's moving.
Velocity vs Speed
- •Speed: Scalar quantity (magnitude only) - how fast
- •Velocity: Vector quantity (magnitude + direction) - how fast and which way
- •Two objects with same speed can have different velocities if moving in different directions
Velocity Formulas
Basic Velocity
v = d / t
where d = distance, t = time
Velocity with Acceleration
v = u + at
where u = initial velocity, a = acceleration, t = time
Average Velocity
v_avg = (u + v) / 2
where u = initial velocity, v = final velocity
Applications of Velocity
- •Transportation: Vehicle speed limits, aircraft navigation
- •Sports: Ball velocity in baseball, swimming speeds
- •Engineering: Fluid flow rates, machinery operation
- •Astronomy: Orbital velocities, escape velocity
Important Velocity Concepts
- •Relative Velocity: Velocity of one object relative to another
- •Angular Velocity: Rate of rotation around an axis
- •Escape Velocity: Minimum speed to escape gravitational pull
- •Terminal Velocity: Maximum falling speed due to air resistance
