Newton's First Law Practice

Front

What is Newton's First Law?

Back

An object at rest will remain at rest, and an object in motion will remain in motion with a constant velocity, unless acted upon by an external force.

Front

What is inertia?

Back

The resistance of an object to any change in its motion.

Front

Which of the following is a real-world example of Newton's First Law?

Back

A car continuing to move forward after the driver takes their foot off the gas pedal.

Front

What did Galileo contribute to Physics regarding motion?

Back

A force is not needed to keep an object in motion.

Front

What happens to a ball rolling down a hill?

Back

It will eventually come to a stop due to external forces like friction.

Front

What is the relationship between mass and inertia?

Back

The greater the mass of an object, the greater its inertia.

Front

How does friction affect motion?

Back

Friction is a force that opposes motion, causing objects to slow down or stop.

Front

What is an example of an object at rest?

Back

A book lying on a table.

Front

What is an example of an object in motion?

Back

A car driving down the road.

Front

What is the role of an external force in motion?

Back

An external force can change the state of motion of an object.
