Front

A substance that is applied to a surface to reduce the friction between the surfaces of 2 objects is called

Back

Lubricants are substances like oil or grease that help reduce friction between surfaces.

Front

Gravitational force increases as mass increases.

Back

True. The gravitational force between two objects increases as the mass of either object increases.

Front

The distance traveled divided by the time in which the motion occurred is called

Back

Speed is calculated as distance divided by time.

Front

What is inertia?

Back

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

Front

What is the difference between speed and velocity?

Back

Speed is a scalar quantity (magnitude only), while velocity is a vector quantity (magnitude and direction).

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 is the unit of force?

Back

The unit of force is the Newton (N).
