Free Body Diagram Practice Flashcard

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 that surface.

Front

What is gravity?

Back

A force that attracts two bodies towards each other, commonly experienced as the force pulling objects towards the Earth.

Front

What is the weight force?

Back

The force exerted by gravity on an object, calculated as the mass of the object multiplied by the acceleration due to gravity.

Front

What is frictional force?

Back

A force that opposes the motion of an object, acting parallel to the surfaces in contact.

Front

What is tension force?

Back

A pulling force transmitted through a string, rope, or cable when it is pulled tight.

Front

What is an action-reaction pair?

Back

For every action, there is an equal and opposite reaction, as stated in Newton's third law of motion.

Front

How can the number of forces in a free body diagram vary?

Back

Different objects can experience different numbers of forces depending on their interactions with other objects.

Front

What is static friction?

Back

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

Front

What is inertia?

Back

The tendency of an object to resist changes in its state of motion.
