Can the motion of a body be accelerated even when it is moving unifromly ?

Assertion : A body may be accelerated even when it is moving uniformly. Reason : When direction of motion of the body is changing then body may have acceleration

Assertion : Linear momentum of a body changes even when it is moving uniformly in a circle. Reason : In uniform circular motion velocity remain constant.

Assertion : Linear momentum of a body changes even when it is moving uniformly in a circle. Reason : Force required to move a body uniformly along a straight line is zero.

Say Yes or No: a. Can an object moving towards north have acceleration towards south? b. Can an object reverse the direction of its motion even thouth it has reverse the direcleration? C. Can an object reverse the derction of its acceleration even though it continues to move in the same dirction? d. Average speed is the magnitude of average velocity e. At any instant of time. the directions of change in velocity and acceleration are differnt.

What is the acceleration of a body moving with uniform velocity ?

What is the acceleration of a body moving with uniform velocity ?

Assertion- The speed of a body can be be negative. Reason- If the body is moving in the opposite direction of positive motion, then its speed is negative.
