Question

newtons first law of motion states an object at rest will remain at rest and an object in motion will remain in motion unless acted upon by an unbalanced force on it.
inertia is the tendency of an object to resist a change in motion.
examples of newtons first law of motion:

• a ball rolling down a hill keeps rolling until another force stops it.
• a book is pushed across a desk and it keeps sliding until it reaches the edge or an outside force acts upon it.
• a soccer ball is at rest, and will remain at rest until another force acts on it, like a kick.

choose the correct answer
what is an example of newtons first law of motion?
a roller skater can skate faster than they can run.
a roller skater glides across a track until another force stops them.
a roller skater sitdown.

Explanation:

Newton's First Law states objects maintain motion/rest unless acted on by a force. The correct option describes a roller skater moving until stopped by another force, matching this law.

Answer:

A roller skater glides across a track until another force stops them.
