Freebody diagrams

Front

What is a free body diagram (FBD)?

Back

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

Front

What does the net force represent in physics?

Back

The overall force acting on an object after all the individual forces are combined.

Front

How do you calculate net force?

Back

Net force is calculated by adding all the forces acting on an object, taking into account their directions.

Front

What is the formula for Newton's second law of motion?

Back

F_net = m * a, where F_net is the net force, m is mass, and a is acceleration.

Front

If an object has a mass of 2 kg and is accelerating at 3 m/s², what is the net force acting on it?

Back

6 N (calculated using F_net = m * a).

Front

What does it mean if the net force is zero?

Back

The object is in equilibrium, meaning it is either at rest or moving at a constant velocity.

Front

What forces act on a bookbag resting on the floor?

Back

The gravitational force acting downwards and the normal force acting upwards.

Front

What is the direction of the gravitational force on an object?

Back

Downward, towards the center of the Earth.

Front

What is air resistance?

Back

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

Front

What happens to the net force when an object is falling with no air resistance?

Back

The net force equals the weight of the object, acting downward.
