Free body diagrams 2

Front

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 do?

Back

It acts perpendicular to the surface and supports the weight of an object resting on it.

Front

What is the weight force?

Back

The force due to gravity acting on an object, calculated as mass times the acceleration due to gravity (W = mg).

Front

Define frictional force.

Back

The force that opposes the relative motion of two surfaces in contact.

Front

What is tension force?

Back

The force transmitted through a string, rope, or cable when it is pulled tight by forces acting from opposite ends.

Front

What is spring force?

Back

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

Front

What is buoyant force?

Back

The upward force exerted by a fluid that opposes the weight of an object immersed in it.

Front

What is applied force?

Back

The force that is applied to an object by a person or another object.

Front

What is static friction?

Back

The frictional force that prevents two surfaces from sliding past each other.

Front

What is kinetic friction?

Back

The frictional force that acts between moving surfaces.
