Front

What is a free-body diagram?

Back

A free-body diagram is a type of physical model that represents the forces acting on a system.

Front

What is the term for a force that equals the sum of two or more forces?

Back

The term used to describe a force that equals the sum of two or more forces is the resultant force.

Front

What is the definition of a newton?

Back

A newton is the force required to accelerate a one-kilogram mass by one meter per second squared.

Front

What does the kelvin scale measure?

Back

The kelvin scale measures absolute temperature, starting from absolute zero.

Front

What is the significance of significant digits in measurements?

Back

Significant digits indicate the precision of a measurement and help convey the certainty of the data.

Front

What is the difference between a scalar and a vector quantity?

Back

A scalar quantity has only magnitude, while a vector quantity has both magnitude and direction.

Front

What is the principle of equilibrium in physics?

Back

The principle of equilibrium states that an object is in equilibrium when the sum of the forces acting on it is zero.
