Question

an astronaut in deep space throws a tool. according to newtons first law, what path will the tool follow? it will eventually slow down and stop as its force runs out. it will curve in a circle as it looks for gravity. it will stop immediately after leaving the astronauts hand. it will travel in a straight line at a constant speed, as there are no significant unbalanced forces acting on it.

Explanation:

Newton's First Law states that an object in motion will stay in motion with a constant velocity (in a straight line) unless acted upon by an unbalanced force. In deep space, there are no significant unbalanced forces (like air resistance or strong gravitational pulls in this context) acting on the tool after it leaves the astronaut's hand.

• The first option is wrong because there's no "force running out" concept in Newtonian mechanics for motion; objects move due to inertia.
• The second option is incorrect as there's no centripetal force (to make it move in a circle) mentioned or present in the deep - space scenario described.
• The third option is wrong because of the principle of inertia; the tool won't stop immediately just because it leaves the hand.

Answer:

It will travel in a straight line at a constant speed, as there are no significant unbalanced forces acting on it.
