Balanced and Unbalanced Forces

Front

What is the definition of balanced forces?

Back

Balanced forces are forces that are equal in size and opposite in direction, resulting in a net force of 0 N, causing no change in the object's motion.

Front

What is the definition of unbalanced forces?

Back

Unbalanced forces are forces that are not equal in size or opposite in direction, resulting in a net force greater than 0 N, causing a change in the object's motion.

Front

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

Back

When the net force acting on an object is zero, the object remains at rest or continues to move at a constant speed in a straight line.

Front

How does friction affect the motion of an object?

Back

Friction opposes the motion of an object, acting in the opposite direction to the applied force, and can slow down or stop the object.

Front

What factors affect the amount of friction between two surfaces?

Back

The amount of friction between two surfaces is affected by the roughness of the surfaces and the normal force pressing them together.

Front

What is the normal force?

Back

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

Front

How can you determine if an object is in equilibrium?

Back

An object is in equilibrium if the sum of all forces acting on it is zero, meaning it experiences balanced forces.

Front

What is an example of balanced forces in everyday life?

Back

An example of balanced forces is a book resting on a table, where the gravitational force downward is balanced by the normal force upward.

Front

What is an example of unbalanced forces in everyday life?

Back

An example of unbalanced forces is a car accelerating forward, where the engine's force exceeds the frictional force opposing its motion.

Front

What is the relationship between mass and inertia?

Back

Inertia is the tendency of an object to resist changes in its state of motion, and it is directly related to the object's mass; greater mass means greater inertia.
