Free body diagrams

Front

What symbol do we use to represent a 'body' in a free-body diagram?

Back

A small dot.

Front

What is the direction of the force of gravity acting on an object?

Back

Straight down.

Front

How do you calculate the net force when given multiple forces acting in opposite directions?

Back

Subtract the smaller force from the larger force and indicate the direction of the larger force.

Front

If a box is moving to the left up a ramp, which way is the force of friction pointing?

Back

Down the ramp to the right.

Front

What is the NET FORCE if there are forces of 8 N to the left and 4 N to the right?

Back

4 N to the left.

Front

What does a free-body diagram illustrate?

Back

The forces acting on a single object.

Front

What is the role of normal force in a free-body diagram?

Back

It acts perpendicular to the surface and supports the weight of the object.

Front

What is the effect of balanced forces on an object?

Back

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

Front

What is the significance of the direction of forces in a free-body diagram?

Back

The direction indicates how the forces will affect the motion of the object.

Front

What happens to an object when the net force acting on it is not zero?

Back

The object will accelerate in the direction of the net force.
