Balanced / Unbalanced Forces

Front

What are balanced forces?

Back

Balanced forces are two or more forces acting on an object that are equal in size and opposite in direction, resulting in no change in motion.

Front

What are unbalanced forces?

Back

Unbalanced forces occur when two or more forces acting on an object are not equal, causing the object to accelerate in the direction of the net force.

Front

What is net force?

Back

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

Front

How does friction affect motion?

Back

Friction is a force that opposes motion between two surfaces in contact, affecting the speed and direction of moving objects.

Front

What happens to an object in motion if no net force acts on it?

Back

If no net force acts on an object in motion, it will continue to move at a constant speed in a straight line.

Front

What is inertia?

Back

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

Give an example of balanced forces in everyday life.

Back

A book resting on a table experiences balanced forces: the weight of the book (downward force) is balanced by the normal force from the table (upward force).

Front

Give an example of unbalanced forces in everyday life.

Back

A soccer ball being kicked experiences unbalanced forces: the force of the kick is greater than the opposing forces, causing it to accelerate.

Front

What is the relationship between mass and acceleration in unbalanced forces?

Back

According to Newton's second law, the acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass (F=ma).

Front

What is the effect of balanced forces on an object's motion?

Back

Balanced forces do not change an object's motion; the object remains at rest or continues to move at a constant speed.
