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

Back

Objects inside the vehicle will continue moving forward due to inertia.

Front

What is friction?

Back

Friction is a force that resists motion between two surfaces that are in contact.

Front

How does friction affect the motion of objects?

Back

Friction opposes the motion of objects, slowing them down or preventing them from moving.

Front

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

Back

A soccer ball remains at rest until kicked by a player.

Front

What is the relationship between mass and inertia?

Back

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

Front

What is an unbalanced force?

Back

An unbalanced force is a force that causes an object to change its state of motion.

Front

How does friction vary with different surfaces?

Back

Friction can be greater on rough surfaces and less on smooth surfaces.

Front

What is the effect of friction on a sliding object?

Back

Friction will cause the sliding object to slow down and eventually stop.
