Forces and Force Diagrams

What is the Net Force?

• The total weight of an object.

• The sum of all forces acting on an object, taking into account their direction.

• The force exerted by gravity on an object.

• The resistance an object encounters when moving through a fluid.

What is a force diagram?

• A visual representation showing all the forces acting on an object, including their direction and magnitude.

• A chart that lists all the forces without any visual representation.

• A diagram that only shows the direction of forces without their magnitudes.

• A graphical representation of the motion of an object over time.

What happens when forces are unbalanced?

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

• The object will remain at rest.

• The object will move at a constant speed.

• The object will change its shape.

What is an Unbalanced Force?

• When the forces acting on an object are equal, resulting in no acceleration.

• When the forces acting on an object are not equal, causing the object to accelerate in the direction of the net force.

• When an object is at rest and no forces are acting on it.

• When the forces acting on an object are balanced, leading to a constant velocity.

What does a free-body diagram represent?

• A diagram that shows all the forces acting on a single object, helping to analyze the object's motion.

• A graphical representation of the energy levels in a system.

• A chart that lists all the possible outcomes of an experiment.

• A visual tool used to represent the relationships between different variables.

What happens when forces are balanced?

• The object accelerates in the direction of the net force.

• The object remains at rest or continues to move at a constant speed in a straight line.

• The object changes direction suddenly.

• The object experiences an increase in mass.

How does friction affect motion?

• Friction increases the speed of an object.

• Friction has no effect on motion.

• Friction opposes the motion of an object, making it harder to start moving or to keep moving.

• Friction only affects objects at rest.

What is the significance of direction in force diagrams?

• It determines the color of the force arrows.

• It indicates how forces will affect the motion of the object, determining whether it will accelerate or remain at rest.

• It shows the magnitude of the forces involved.

• It is only important for static objects.

What is Air Resistance?

• A type of frictional force that acts against the motion of an object moving through air.

• A force that propels an object forward in a vacuum.

• A gravitational force that pulls objects towards the Earth.

• A type of energy that is released during combustion.

What is Normal Force?

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

• The force that opposes the motion of an object sliding on a surface.

• The gravitational force acting on an object in free fall.

• The force that causes an object to accelerate in the direction of the net force.
