Front

The force that opposes motion between two surfaces in contact with each other is called __________.

Front

What is Newton's First Law of Motion?

Back

An object at rest stays at rest, and an object in motion stays in motion unless acted upon by a net external force.

Front

What does inertia depend on?

Back

Inertia depends on the mass of an object.

Front

What is the unit of force in the International System of Units (SI)?

Back

Newton (N)

Front

What is the relationship between mass and acceleration in Newton's Second Law?

Back

Acceleration is directly proportional to the net force acting on an object and inversely proportional to its mass.
