Free Body Diagrams

What is a Free Body Diagram?

Back

A graphical representation used to visualize the forces acting on an object.

Front

What does the Normal force represent in a Free Body Diagram?

Back

The force exerted by a surface to support the weight of an object resting on it, acting perpendicular to the surface.

Front

What is the formula for calculating weight?

Back

W = mg, where W is weight, m is mass, and g is the acceleration due to gravity.

Front

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

Back

Newton (N)

Front

What does the coefficient of friction represent?

Back

A measure of how much frictional force exists between two surfaces in contact.

Front

What is the difference between static and kinetic friction?

Back

Static friction prevents motion between two surfaces, while kinetic friction acts on moving surfaces.

Front

How do you calculate the coefficient of static friction?

Back

Coefficient of static friction (μs) = Force of static friction / Normal force.

Front

What is the gravitational acceleration on Earth?

Back

Approximately 9.8 m/s².

Front

What is the spring force?

Back

The force exerted by a compressed or stretched spring, described by Hooke's Law: F = -kx.

Front

What is the role of the weight force in a Free Body Diagram?

Back

It represents the gravitational force acting downward on an object, equal to its mass times the acceleration due to gravity.
