1. Accuracy: Accuracy is a degree to which
the measurement represents the actual
value.2. Sensitivity: Sensitivity is the ability to
detect small change in a measurement.3. Consistency: Consistency is the ability to
register the same reading when a
measurement is repeated.4. Scalar quantity: he quantity which has
magnitude.!. "ector quantity: he quantity which has
magnitude and direction.#. "elocity: he rate o$ change o$
displacement.%. Acceleration: he rate o$ change o$
velocity.&. 'nertia: he tendency o$ an ob(ect to
maintain it state o$ motion in a straight line.). *omentum: he product o$ mass and
velocity.1+. 'mpulse: he change o$ momentum.
11. 'mpulsive $orce: he rate o$ change o$momentum.
12. ,ree $all: An ob(ect $alling under the $orce
o$ gravity.
