NMAT Review Physics Questions With
Correct Answers

Motion graphs - CORRECT ANSWER✔✔-When distance slope is
| | | | | | | |



INCREASING (and positive), velocity slope is POSITIVELY inclined, and
| | | | | | | | |



acceleration slope is POSITIVE and horizontal.
| | | | |




When distance slope is CONSTANT, velocity slope is HORIZONTAL line,
| | | | | | | | | |



and acceleration slope is ZERO
| | | |




When distance slope is DECREASING (but still positive), velocity slope is
| | | | | | | | | | |



NEGATIVELY inclined, and acceleration slope is NEGATIVE and horizontal
| | | | | | | |




When distance slope is HORIZONTAL, velocity slope is at ZERO.
| | | | | | | | |




When distance slope is NEGATIVE, velocity slope is in the NEGATIVE
| | | | | | | | | |




A FLATTENING distance curve means velocity slope is APPROACHING
| | | | | | | | |



ZERO
