23 FOCUSED TOOLS
Motion & kinematics calculators
Explore speeds, accelerations and ideal trajectories.
Choose the right calculation
Choose a reference direction before using signed velocities. Constant-acceleration models do not capture variable braking or drag. Projectile tools explicitly state launch and landing assumptions.

Speed Calculator
Find average speed from total distance and elapsed time.
Acceleration Calculator
Find constant average acceleration from a change in velocity.
Free Fall Time Calculator
Estimate fall time from rest under constant gravity without air resistance.
Constant Acceleration Distance Calculator
Find displacement from initial velocity, time and constant acceleration.
Final Velocity Calculator
Calculate velocity after a period of constant acceleration.
Stopping Distance Calculator
Find ideal braking distance from speed and a constant deceleration magnitude.
Reaction Distance Calculator
Find distance travelled at constant speed during a reaction delay.
Projectile Range Calculator
Find horizontal range for a projectile landing at its launch height without drag.
Projectile Maximum Height Calculator
Estimate rise above launch height in ideal projectile motion.
Centripetal Acceleration Calculator
Calculate inward acceleration for uniform circular motion.
Centripetal Force Calculator
Find net inward force needed for uniform circular motion.
Angular Velocity Calculator
Convert rotations per minute into angular velocity.
Tangential Speed Calculator
Find linear speed at a radius on a rotating object.
Average Velocity Calculator
Find average velocity along a chosen coordinate direction.
Velocity From Distance and Acceleration Calculator
Use the time-independent kinematic relationship to find a final speed magnitude.
Projectile Flight Time Calculator
Find ideal total flight time for a projectile returning to launch height.
Horizontal Projectile Time Calculator
Find time to fall for a projectile launched horizontally from a height.
Horizontal Projectile Range Calculator
Find horizontal travel before an ideal horizontally launched object reaches the ground.
Relative Speed Calculator
Find relative speed between two objects moving along the same line.
Catch Up Time Calculator
Find when a faster pursuer reaches a slower object ahead.
Meeting Time Calculator
Find time for two approaching objects to meet.
Rotational Period Calculator
Find time per full rotation from a rotational speed.
Angular Acceleration Calculator

Are displacement and distance interchangeable?
No. Displacement is the signed or directed change in position; distance counts the length of the path travelled.
