A
AccelerationRate of change of velocity. | |
AssumptionA condition accepted when constructing a model. | |
Average accelerationTotal velocity change divided by the time interval. | |
Average velocityTotal displacement divided by total time. | |
B
Braking distanceDistance travelled while a vehicle slows after braking begins. | |
C
Constant velocityMotion with unchanged speed and direction. | |
D
Dimensional consistencyAgreement between the units of all terms in an equation. | |
Dimensional checkA comparison of units used to test whether an equation or answer is consistent. | |
DisplacementChange in position, including direction. | |
DistanceTotal length of the path travelled. | |
