What is net force?

Back

Net force is the overall force acting on an object when all the individual forces are combined. It determines the object's acceleration.

What does it mean for forces to be balanced?

Back

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

What does it mean for forces to be unbalanced?

Back

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

How do you calculate net force?

Back

Net force is calculated by adding all the forces acting on an object, taking into account their direction. If forces are in opposite directions, subtract the smaller force from the larger one.

What is acceleration?

Back

Acceleration is the rate of change of velocity of an object. It occurs when an object speeds up, slows down, or changes direction.

What is the relationship between force and acceleration?

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).

What is gravitational force?

Back

Gravitational force is the attractive force between two masses. On Earth, it pulls objects toward the center of the planet.

What is the formula for calculating force?

Back

The formula for calculating force is F = ma, where F is force, m is mass, and a is acceleration.

What is 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 the book down is balanced by the normal force of the table pushing it up.

Front

What is an example of unbalanced forces in everyday life?

Back

An example of unbalanced forces is a car accelerating forward. The engine's force is greater than the frictional force opposing it.
