Question

If a hockey puck is made to slide along a straight line on a completely frictionless surface, which statement about the motion of 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

Answer 1

The hockey puck will continue in the same speed in a continues straight line

Answer 2

Answer:

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.
