Answer 1

Answer:

In Second Blank it will be KINETIC FRICTION & In Third Blank it will come LESSER THAN

Answer 2

$\huge{\tt{\red{Answer:}}}$

$\rule{300}{2}$

Ans1-Zero

Ans2-Rolling

Ans3-More

$\huge{\tt{\orange{Explanation:}}}$

Ans1-According to first law of motion the object will remain in motion or will remain in rest if there is no external force is is acting on it.The force should be zero if the object have no change.

$\rule{300}{2}$

Ans2-As the wheels of trolley are round in shape they have have a less area of contact with the surface on which it is moving so friction also become less. Therefore, Rolling friction is Required Answer.

$\rule{300}{2}$

Ans3-Static Friction is more than sliding friction because when a object is at rest the irregularities become interlocked ,So we have to apply more force to overcome the force of friction but when we move a sliding object,the surface irregularities does not get much time to interlock with each other As a result, the friction decreases and have to apply less force as compared to moving a object from rest.
