Explanation / Answer

Change in momentum -

(i) A planet is orbiting the sun in a circular orbit (Because each time its velocity is changing)

(ii) A car is holding a steady speed around a curve (Velocity is changing)

(iii) A ball is in freefall after being dropped from a high window. (Velocity is increasing)

(iv) A car is slowing down for a stop sign (velocity is decreasing)

(v) A car is speeding up after being stopped.

(vi) A planet is orbiting the sun in an elliptical orbit

Constant momentum -

(i) A car driving at 100 km/hr on a straight road (Because its velocity is constant).

(ii) A spaceship is coasting without engine power in deep space.

(iii) An elevator is going upward at constant speed.
