Kinematic Equations:
From: | To: |
Velocity is the rate of change of displacement with time, while acceleration is the rate of change of velocity with time. These fundamental kinematic quantities describe how an object's motion changes over time.
The calculator uses the kinematic equations:
Where:
Explanation: These equations describe motion under constant acceleration, connecting initial and final velocities with acceleration and time.
Details: Calculating velocity and acceleration is essential in physics, engineering, and various practical applications including vehicle dynamics, projectile motion, and mechanical systems analysis.
Tips: Enter initial velocity, final velocity, and time in appropriate units. Acceleration can be calculated automatically or provided as input. Time must be greater than zero.
Q1: What if acceleration is not constant?
A: These equations only apply for constant acceleration. For variable acceleration, calculus-based methods are required.
Q2: Can negative values be used?
A: Yes, negative values indicate direction. Negative acceleration means deceleration or acceleration in the opposite direction.
Q3: What are typical units for these quantities?
A: Velocity is typically measured in m/s or km/h, acceleration in m/s², and time in seconds.
Q4: How accurate are these calculations?
A: The calculations are mathematically exact for constant acceleration scenarios in ideal conditions.
Q5: When are these equations not applicable?
A: These equations don't apply to relativistic speeds (near light speed) or quantum mechanical systems.
