Unbalanced Forces

Front

What is an unbalanced force?

Back

An unbalanced force is a force that causes an object to accelerate, change direction, or change its state of motion. It occurs when the total forces acting on an object are not equal.

Front

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.

Front

How do you calculate net force when multiple forces are acting on an object?

Back

To calculate net force, you must add the forces acting in the same direction and subtract the forces acting in the opposite direction.

Front

What is Newton's Second Law of Motion?

Back

Newton's Second Law states that 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 happens to an object when the forces acting on it are balanced?

Back

When the forces acting on an object are balanced, the object remains at rest or continues to move at a constant speed in a straight line.

Front

What is an example of unbalanced forces in everyday life?

Back

An example of unbalanced forces is when a person pushes a shopping cart; if the push is stronger than the friction, the cart accelerates.

Front

What is the difference between balanced and unbalanced forces?

Back

Balanced forces do not change an object's motion, while unbalanced forces cause an object to accelerate or change direction.

Front

If a car is accelerating, what can we say about the forces acting on it?

Back

If a car is accelerating, the forces acting on it are unbalanced, resulting in a net force in the direction of the acceleration.

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.

Front

What is the role of friction in motion?

Back

Friction is a force that opposes motion between two surfaces in contact. It can be balanced or unbalanced depending on the situation.
