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 an unbalanced force.

Front

What is inertia?

Back

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

Front

What is an unbalanced force?

Back

An unbalanced force is a force that causes an object to change its state of motion, either by starting to move, stopping, or changing direction.

Front

What happens to a soccer ball at rest when no forces act on it?

Back

The soccer ball will remain at rest until an unbalanced force, such as a kick, acts on it.

Front

How does friction affect motion?

Back

Friction is a force that opposes the motion of an object, making it harder for the object to start moving or to keep moving.

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 an object with less mass.

Front

What is a balanced force?

Back

Balanced forces are equal in size and opposite in direction, resulting in no change in the motion of an object.

Front

Can an object be in motion if no forces are acting on it?

Back

Yes, an object can continue moving at a constant velocity if no net forces are acting on it.

Front

What is an example of Newton's First Law of Motion in everyday life?

Back

A soccer ball remains motionless on the field until a player kicks it.

Front

What is the effect of an unbalanced force on a stationary object?

Back

An unbalanced force will cause the stationary object to start moving.
