Front

What do free-body diagrams use to represent forces?

Back

Arrows are used to represent forces in free-body diagrams.

Front

If an object is gaining speed to the right, which type of free-body diagram would likely explain this motion?

Back

A free-body diagram that shows a net force acting to the right.

Front

What does a free-body diagram of an object on a table experiencing friction and accelerating to the right look like?

Back

It should show a force arrow pointing to the right (net force) and a friction force arrow pointing to the left.

Front

What type of force must be present for an object to accelerate?

Back

An unbalanced force is required for an object to accelerate.

Front

What is a free-body diagram?

Back

A free-body diagram is a graphical representation used to visualize the forces acting on an object.

Front

What does the length of an arrow in a free-body diagram represent?

Back

The length of the arrow represents the magnitude of the force.

Front

What is the difference between balanced and unbalanced forces?

Back

Balanced forces result in no change in motion, while unbalanced forces cause an object to accelerate.

Front

How do you determine the net force acting on an object?

Back

The net force is determined by vectorially adding all the forces acting on the object.

Front

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

Back

The object remains at rest or continues to move at a constant velocity.

Front

What is friction?

Back

Friction is a force that opposes the motion of an object.
