A
AccelerationThe rate of change of velocity. | |
Acceleration due to gravity(g) – Approximately 9.8 m/s2 downward near Earth's surface. | |
AccelerometerA sensor used to measure acceleration. | |
Air resistanceA drag force that opposes motion through air. | |
Average accelerationTotal change in velocity divided by the time taken. | |
B
Braking distanceThe distance travelled while a vehicle slows under braking. | |
C
Centripetal accelerationAcceleration directed toward the centre of circular motion. | |
Constant accelerationVelocity changing by the same amount each second. | |
Crumple zoneA vehicle structure designed to deform during a collision and help increase stopping time while managing energy. | |
Change in velocity(Δv) – Final velocity minus initial velocity. | |
