If a hockey puck is made to slide along a straight line on a completely frictionless surface, which statement about the motion o
f the hockey puck is true? The hockey puck will come to a halt immediately. The hockey puck will continue moving with constant velocity along a straight line. The hockey puck will accelerate and continue moving in straight line. The hockey puck will continue moving in random direction. NextReset
The hockey puck will continue moving with constant velocity along a straight line.
Explanation:
Friction decelerates the motion of a moving body. In the absence of friction on smooth surface an object in moving with uniform velocity will continue to move in a straight line until acted upon by some force. A rough surface has a higher friction and it will decelerate a moving object such that the object will not be able to travel very far in a uniform velocity but quickly come to halt.
