๐ŸงญVelocity vs Acceleration๐Ÿš€

Velocity and acceleration are linked but distinct. One describes motion itself; the other describes how that motion is changing.

๐ŸงญVelocity
  • โœ“Describes the rate of change of position
  • โœ“Measured in meters per second (m/s)
  • โœ“A vector with magnitude and direction
  • โœ“Constant velocity means no acceleration
  • โœ“Equal to displacement divided by time
๐Ÿš€Acceleration
  • โœ“Describes the rate of change of velocity
  • โœ“Measured in meters per second squared (m/sยฒ)
  • โœ“A vector that can speed up, slow down or turn motion
  • โœ“Zero acceleration means constant velocity
  • โœ“Linked to net force by Newton's second law

Verdict

Velocity tells you the current state of motion; acceleration tells you how it is changing. A car at steady speed has velocity but zero acceleration; pressing the pedal creates acceleration.

Frequently asked

Can an object accelerate without changing speed?+

Yes. Changing direction is acceleration. A car turning at constant speed is still accelerating.

What does negative acceleration mean?+

It usually means slowing down (deceleration), or speeding up in the negative direction.

How is acceleration related to force?+

Newton's second law states force equals mass times acceleration, so any net force produces acceleration.
