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.

The hockey puck will continue moving with constant velocity along a straight line.

Explanation:

As per Newton's first law we know that when there is no net force on an object then the velocity of object will always remains constant

Or we can say that the acceleration of an object will be zero when the force applied on the object is zero.

As per Newton's law we know

so we will have

a = 0

so object will continue in straight line with same uniform speed without any change in magnitude as well as any change in direction

so correct answer will be

The hockey puck will continue moving with constant velocity along a straight line.
