Uniformly accelerated motion
Acceleration, speed and displacement under constant acceleration.
The entire theory of the lesson is collected here; you can read it without an account. In interactive mode, the same theory appears as cards, followed by questions. with checking the answer and task, and progress is saved.
Basic Concepts
Uniformly accelerated motion
Movement with constant acceleration.
Over equal time intervals, the speed changes by the same amount; The graph of speed versus time is straight.
Physical quantities
Acceleration
Speed of change of speed.
Unit: meters per second squared ·
Initial speed
The speed of the body at the initial moment.
Unit: meter per second ·
Lesson formulas
Acceleration
The acceleration modulus is equal to the change in speed divided by time.
Acceleration unit
Acceleration is measured in meters per second per second.
Speed at constant acceleration
The final speed is determined by the initial speed and the change in speed over time.
Moving through medium speed
Displacement is equal to average speed times time.
Moving through time
The displacement consists of the initial movement and the addition of acceleration.
Moving without time
Displacement relates initial and final velocities to acceleration.
