force diagrams

Front

What is a force diagram?

Back

A force diagram is a graphical representation that shows all the forces acting on an object, including their direction and magnitude.

Front

What does it mean for forces to be balanced?

Back

Forces are balanced when the net force acting on an object is zero, resulting in no change in motion.

Front

What is an unbalanced force?

Back

An unbalanced force is a force that causes an object to change its state of motion, resulting in acceleration.

Front

What is the normal force?

Back

The normal force is the force exerted by a surface to support the weight of an object resting on it, acting perpendicular to the surface.

Front

How does friction affect motion?

Back

Friction is a force that opposes the motion of an object, acting parallel to the surface in contact.

Front

What is the role of gravity in force diagrams?

Back

Gravity is a force that pulls objects toward the center of the Earth, acting downward in force diagrams.

Front

What is the difference between static and kinetic friction?

Back

Static friction acts on objects at rest and prevents them from moving, while kinetic friction acts on moving objects and opposes their motion.

Front

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

Back

The net force can be determined by vectorially adding all the forces acting on the object, taking into account their directions.

Front

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

Back

When the net force is not zero, the object will accelerate in the direction of the net force.

Front

What is the significance of direction in force diagrams?

Back

Direction is crucial in force diagrams as it indicates the way each force is acting on the object, affecting the net force and motion.
