1st Law of Motion and Friction flashcard

Front

What does Newton's First Law of Motion state?

Back

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

Front

What is inertia?

Back

Inertia is the tendency of an object to resist changes in its state of motion.

Front

Provide an example of Newton's First Law of Motion in everyday life.

Back

A soccer ball remains motionless until it is kicked by a player.

Front

What happens to objects in a moving vehicle when the vehicle suddenly stops?

Back

The objects will continue moving forward due to inertia and may slide toward the front of the vehicle.

Front

What is friction?

Back

Friction is a force that resists the relative motion of two surfaces in contact.

Front

How does increasing force affect the motion of an object?

Back

Increasing the force applied to an object will increase its acceleration, allowing it to move farther or faster.

Front

What is the relationship between mass and inertia?

Back

The greater the mass of an object, the greater its inertia, meaning it will resist changes in its motion more than a lighter object.

Front

What is the effect of friction on moving objects?

Back

Friction opposes the motion of moving objects, causing them to slow down or stop.

Front

What is the natural tendency of objects in motion?

Back

Objects in motion tend to keep doing what they are doing, maintaining their velocity unless acted upon by an external force.

Front

What role does a net external force play in motion?

Back

A net external force is required to change the motion of an object, whether to start, stop, or change its direction.
