Assertion : A lift is ascending with decreasing speed means acceleration of lift is downwards.
Reason : A body always moves in the direction of its acceleration.

(A): A lift ascending with decreasing speed means acceleration of lift is down wards. (R) : A body always moves in the direction of its acceleration.
