A body falls freely. What is constant ?

A : For a particle moving in a straight line, its acceleration must be either parallel or antiparallel to velocity. R : A body moving along a curved path may have constant acceleration.

A body whose speed in a particular direction is constant

Name the type of motion in which a body has a constant speed but not constant velocity.

Assertion: A body having non zero acceleration can have a constant velocity. Reason: Acceleration is the rate of change of velocity.

Assertion : If there is no external torque on a body about its centre of mass, then the velocity of the centre of mass remains constant. Reason : The linear momentum of an isolated system remains constant.

Assertion: If linear momentum of a particle is constant, then its angular momentum about any point will also remain constant. Reason: Linear momentum remains constant if F_(n et)=0 and angular momentum remains constant if tau_(n et)=0
