What are balanced forces?

Back

Balanced forces are two or more forces acting on an object in such a way that they cancel each other out, resulting in no change in the object's motion.

Front

What are unbalanced forces?

Back

Unbalanced forces occur when two or more forces acting on an object do not cancel each other out, causing the object to accelerate in the direction of the net force.

Front

What is the force of gravity?

Back

The force of gravity is the attractive force between two masses, such as the Earth and an object, which pulls the object toward the center of the Earth.

Front

How does gravity affect falling objects?

Back

Gravity causes objects to fall towards the Earth at an acceleration of approximately 9.81 m/s², regardless of their mass.

Front

What is the relationship between force, mass, and acceleration?

Back

According to Newton's second law of motion, the relationship is described by the formula F = ma, where F is force, m is mass, and a is acceleration.

Front

What is the definition of force in physics?

Back

A force is a push or pull acting upon an object, which can cause it to change its velocity (speed or direction).

Front

What is the significance of direction in force?

Back

The direction of a force determines the direction in which an object will accelerate; forces have both magnitude and direction.

Front

What happens when forces are balanced?

Back

When forces are balanced, the object remains at rest or continues to move at a constant velocity, as there is no net force acting on it.

Front

What happens when forces are unbalanced?

Back

When forces are unbalanced, the object will accelerate in the direction of the net force, changing its speed or direction.

Front

Can you give an example of balanced forces in everyday life?

Back

An example of balanced forces is a book resting on a table; the force of gravity pulling it down is balanced by the normal force from the table pushing it up.
