(Un)Balanced Forces, Net Force, Free Body Diagram Flashcard

Front

The tendency of an object at rest to stay at rest unless it is acted upon by a force is called _____________.

Back

Inertia

Front

What is the net force?

Back

The sum of all forces acting on an object.

Front

If two forces are acting in the same direction, how do you calculate the net force?

Back

Add the magnitudes of the forces.

Front

What happens when the net force on an object is zero?

Back

The object is in a state of equilibrium and will not accelerate.

Front

What is a free body diagram?

Back

A graphical representation showing all the forces acting on an object.

Front

If a couch is pushed with 35 N to the right and 25 N to the right, what is the net force?

Back

60 N to the right.

Front

What is the difference between balanced and unbalanced forces?

Back

Balanced forces do not change an object's motion; unbalanced forces do.

Front

What is the unit of force?

Back

Newton (N)

Front

If a net force of 4000 N left is acting on an object, what can you say about the forces acting on it?

Back

There is a greater force acting to the left than to the right.

Front

What is the formula for calculating net force?

Back

Net Force = Force1 + Force2 + ... + ForceN.
