Front

What are the four types of forces that can act on an object?

Back

Gravity, friction, normal force, tension.

Front

What is a free-body diagram?

Back

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

Front

How many forces are typically represented in a free-body diagram?

Back

It can vary, but each force acting on the object is represented.

Front

What is the normal force?

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 tension in the context of forces?

Back

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

Front

What does friction do in a force interaction?

Back

Friction opposes the motion of an object, acting parallel to the surface of contact.

Front

What is an interaction diagram?

Back

A diagram that shows the interactions between different objects, often including forces and their directions.

Front

What is the role of gravity in force interactions?

Back

Gravity pulls objects toward the center of the Earth, providing a downward force.

Front

How can you determine the number of forces acting on an object?

Back

By analyzing the free-body diagram and counting all the forces represented.

Front

What is air resistance?

Back

A type of frictional force that opposes the motion of an object through the air.
