Back

Newton (N)

Front

What is inertia?

Back

Inertia is the property of matter that resists changes in its motion.

Front

What is the volume of an object if it is measured to be 25.0 cm³?

Back

The volume of the object is 25.0 cm³.

Front

What is acceleration?

Back

Acceleration is the rate of change of velocity of an object.

Front

What is the relationship between mass, force, and acceleration?

Back

According to Newton's second law, Force = Mass × Acceleration.

Front

What is the definition of velocity?

Back

Velocity is the speed of an object in a specific direction.
