Speed, Distance, Time, Acceleration, Velocity

Speed- how fast- m/s or Km/s

Distance- how far- m or Km

Time- how long- s or min

Equations

1. Speed (m/s) = distance travelled (m) divided by time taken (s)

2. Time (s) = distance travelled (m) divided by speed (m/s)

3. Distance Travelled (m) = Speed (m/s) x Time (s)

acceleration= speed moving up

deceleration= speed slowing down

Acceleration (m/s/s)(m/s squared) = change in velocity (m/s) divided by time taken (s)

Deceleration = same as acceleration but in negative value
