Net Force Review

Front

What is the net force?

Back

The net force is the overall force acting on an object when all the individual forces are combined. It determines the object's motion.

Front

What does it mean if the net force is 0 N?

Back

If the net force is 0 N, it means that all the forces acting on an object are balanced, resulting in no change in motion.

Front

What is a balanced force?

Back

Balanced forces are equal in size and opposite in direction, resulting in no net force and no change in the object's motion.

Front

What is an unbalanced force?

Back

Unbalanced forces are not equal and opposite, resulting in a net force that causes a change in the object's motion.

Front

What is a force?

Back

A force is a push or pull exerted on an object that can cause it to accelerate, change direction, or change shape.

Front

What happens to an object when a net force is applied?

Back

When a net force is applied to an object, it will accelerate in the direction of the net force according to Newton's second law.

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

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.

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 will accelerate.

Front

What is friction?

Back

Friction is a force that opposes the motion of an object, acting in the opposite direction of the applied force.
